Hi piano friends, I've made another free piano technician tool! (Open to feedback and feature fixes).

https://pitchraise.app/index.html

This web-based app enables customers to be able to check if they need a pitch raise as part of the appointment setting process. This runs in the web browser so any modern phone, iOS or Android can use it.

There are no downloads, no cost, no ads, no sign up's - send the link to your customer and let them measure the piano themselves. It's pretty simple. If you have pre-set limits on pitch raises (some techs say -10, others say -20, etc) - ask the customer to open the settings and change the pitch field to YOUR value. 

For tuners - if you enter "0000" in this field a new window will display - you can enter your name or business name and phone number - this generates a link you can copy with a "Deep Link" - when they open the link it will say your name or company, ie. "Denver Piano Service would like you to measure your piano to see if a pitch raise or additional tuning is needed" 

When the customer completes the testing it generates a button to text the results back to you. 

🚨GO LAND MORE PITCH CORRECTION BILLING!! 🚨

(There's a Venmo link on the bottom of the page if you think you'll use this tool or it makes you more money, buy me a ☕️)

Hi Sean

Great work on the app. I like the concept!

One small thought: since pianos can sometimes be sharp, "pitch correction" or "pitch adjustment" might be more flexible than "pitch raise." Just a thought.

Yes, and - the language is very specific - "your piano needs to be tuned, but doesn't need a pitch raise" (even if all 3 samples are "correct") 

the discerning customer isn't going to stop the thought process of needing to be tuned if the barrier for that tuning is a pitch raise or not. Not needing a pitch correction is a sigh of relief, in my opinion.

Sean, This is a very cool tool. I often get customers to play a note on their piano but sometimes the cell phone fidelity is hopeless. The only thing that might need clarification is whether our technician name and cell number is stored anywhere on the website or cloud.

Tremaine, I'm familiar with your work on Piano Scale - I'm honored you're participating in the conversation! The PTG is such an amazing resource… 

The entire app and logic are static html, no server calls or http requests. If you inspect the page, it's all there - the only call that saves data (on the tuner section) is a JavaScript helper to write your personal details to the cache on your local device (so the next time you open the link you don't have to type the details in again, just click copy).

My real goal is putting it into my own gazelle self scheduler and prompting customers to check before tuning. The first feedback as "I don't know what A4 means" - so I stripped out a lot of cool complexity and visual strobe tuner stuff - What's the most basic thing I need? A picture of a piano and audio samples across the midrange. We'll see how the next round of feedback comes in… 

Thanks for checking it out!

Steve - thanks, I totally agree about different customers and technical abilities (or desires to even try). 

these are great questions and I'll be honest - precision isn't particularly the main goal of the app (I'm not writing a replacement for iRCT).

The math is logical for a simple single page of html - how far off of the fundamental pitches of ~220, 440, and 880 are the notes? I'm guessing that discerning technicians will find this app to be unsuitable for ~5c readings. However, for a first-touch customer who doesn't know what's happening with the piano, knowing it's 20-100c flat is easily detectable. 

I appreciate you looking into it!

Sean, actually my question is how well does it do if there's a 10-15 cent spread between the 3 strings of a unison? This isn't a gotcha question, I'm just curious.

My Verituner seems to do some sort of summing thing and gives inaccurate readings that don't reflect any of the strings. I know that there's an ETD that can differentiate, but as you say this isn't a tuning device. If the unisons are wildly out of tune can you still get the relative information you need?

Steve - thanks, I totally agree about different customers and technical abilities (or desires to even try). 

these are great questions and I'll be honest - precision isn't particularly the main goal of the app (I'm not writing a replacement for iRCT).

Sean, I think this is a good idea though it might work better with some customers than others. I'm wondering how it deals with really bad unisons? And alternately, if it could have a module the evaluates unisons as well?

Tremaine, I'm familiar with your work on Piano Scale - I'm honored you're participating in the conversation! The PTG is such an amazing resource… 

The entire app and logic are static html, no server calls or http requests. If you inspect the page, it's all there - the only call that saves data (on the tuner section) is a JavaScript helper to write your personal details to the cache on your local device (so the next time you open the link you don't have to type the details in again, just click copy).

My real goal is putting it into my own gazelle self scheduler and prompting customers to check before tuning. The first feedback as "I don't know what A4 means" - so I stripped out a lot of cool complexity and visual strobe tuner stuff - What's the most basic thing I need? A picture of a piano and audio samples across the midrange. We'll see how the next round of feedback comes in… 

Thanks for checking it out!

Sean, This is a very cool tool. I often get customers to play a note on their piano but sometimes the cell phone fidelity is hopeless. The only thing that might need clarification is whether our technician name and cell number is stored anywhere on the website or cloud.

Yes, and - the language is very specific - "your piano needs to be tuned, but doesn't need a pitch raise" (even if all 3 samples are "correct") 

the discerning customer isn't going to stop the thought process of needing to be tuned if the barrier for that tuning is a pitch raise or not. Not needing a pitch correction is a sigh of relief, in my opinion.

I checked my piano. No pitch raise needed. I guess I'll put off the tuning since it's. It that bad.

Hi Sean

Great work on the app. I like the concept!

One small thought: since pianos can sometimes be sharp, "pitch correction" or "pitch adjustment" might be more flexible than "pitch raise." Just a thought.

Hi piano friends, I've made another free piano technician tool! (Open to feedback and feature fixes).

https://pitchraise.app/index.html

This web-based app enables customers to be able to check if they need a pitch raise as part of the appointment setting process. This runs in the web browser so any modern phone, iOS or Android can use it.

There are no downloads, no cost, no ads, no sign up's - send the link to your customer and let them measure the piano themselves. It's pretty simple. If you have pre-set limits on pitch raises (some techs say -10, others say -20, etc) - ask the customer to open the settings and change the pitch field to YOUR value. 

For tuners - if you enter "0000" in this field a new window will display - you can enter your name or business name and phone number - this generates a link you can copy with a "Deep Link" - when they open the link it will say your name or company, ie. "Denver Piano Service would like you to measure your piano to see if a pitch raise or additional tuning is needed" 

When the customer completes the testing it generates a button to text the results back to you. 

🚨GO LAND MORE PITCH CORRECTION BILLING!! 🚨

(There's a Venmo link on the bottom of the page if you think you'll use this tool or it makes you more money, buy me a ☕️)

------------------------------

Sean, I can see now that the link created has the Tech Name and Phone added to the link to be parsed out server side.

In creating my Tech profile and sending the link to my iPhone, testing my piano, I do not receive a text report. Can you replicate this? I am on an iPhone 6S (I know old - so am I and my tuning lever)

Also, I'm more likely to buy you a cup of coffee if you have both: a Venmo and PayPal option. (grin)

Sean, actually my question is how well does it do if there's a 10-15 cent spread between the 3 strings of a unison? This isn't a gotcha question, I'm just curious.

My Verituner seems to do some sort of summing thing and gives inaccurate readings that don't reflect any of the strings. I know that there's an ETD that can differentiate, but as you say this isn't a tuning device. If the unisons are wildly out of tune can you still get the relative information you need?

Steve - thanks, I totally agree about different customers and technical abilities (or desires to even try). 

these are great questions and I'll be honest - precision isn't particularly the main goal of the app (I'm not writing a replacement for iRCT).

The math is logical for a simple single page of html - how far off of the fundamental pitches of ~220, 440, and 880 are the notes? I'm guessing that discerning technicians will find this app to be unsuitable for ~5c readings. However, for a first-touch customer who doesn't know what's happening with the piano, knowing it's 20-100c flat is easily detectable. 

I appreciate you looking into it!

Steve, Not feeling like a 'gotcha' - I just wanted to clarify the use of the tool... But after you messaged this I'm currently looking at unisons and how they're interpreted by software - the logic is tough! 

What i tested on my own piano (you folks who click the link are all the beta testers!) - I knocked an A4 unsion out of tune and left A3 and A5 clean - it registered a bad note, but because all three weren't bad, it gave a passing grade. if I knocked another the A3 unison out by roughly the amount of the # in the settings box, and it registered 2 out of 3 bad notes and got a provisional pass. 3/3 failures determines the messaging to the customer that yes - 3 notes across your piano are not right.

 As I spend time this evening looking at how to parse beating unisons through data, my head begins to hurt, haha!

Sean, This is a very cool tool. I often get customers to play a note on their piano but sometimes the cell phone fidelity is hopeless. The only thing that might need clarification is whether our technician name and cell number is stored anywhere on the website or cloud.

Yes, and - the language is very specific - "your piano needs to be tuned, but doesn't need a pitch raise" (even if all 3 samples are "correct") 

the discerning customer isn't going to stop the thought process of needing to be tuned if the barrier for that tuning is a pitch raise or not. Not needing a pitch correction is a sigh of relief, in my opinion.

I checked my piano. No pitch raise needed. I guess I'll put off the tuning since it's. It that bad.

Hi Sean

Great work on the app. I like the concept!

One small thought: since pianos can sometimes be sharp, "pitch correction" or "pitch adjustment" might be more flexible than "pitch raise." Just a thought.

Hi piano friends, I've made another free piano technician tool! (Open to feedback and feature fixes).

https://pitchraise.app/index.html

This web-based app enables customers to be able to check if they need a pitch raise as part of the appointment setting process. This runs in the web browser so any modern phone, iOS or Android can use it.

There are no downloads, no cost, no ads, no sign up's - send the link to your customer and let them measure the piano themselves. It's pretty simple. If you have pre-set limits on pitch raises (some techs say -10, others say -20, etc) - ask the customer to open the settings and change the pitch field to YOUR value. 

For tuners - if you enter "0000" in this field a new window will display - you can enter your name or business name and phone number - this generates a link you can copy with a "Deep Link" - when they open the link it will say your name or company, ie. "Denver Piano Service would like you to measure your piano to see if a pitch raise or additional tuning is needed" 

When the customer completes the testing it generates a button to text the results back to you.

OK, The first few times I did not realize that the Send Text to Tremaine Parsons was a button that needed to be pressed. Maybe tweek the wording or make the button more 3D. I incorrectly assumed that the info would send automatically after the test. When pressing the Send Text to... it stuffs my phone number and the information string into the To: portion of the text. It does not parse and put the info string in the text body and text will not send until adding something to body and then send fails due to extra string in To: window. See the screenshot below.

I realize sampling wild unisons is certainly a challenge. Some other beta thoughts are: Could you include voice prompts Play A above Middle C, Play A below Middle C. Or additional helpful text for users to find the notes. I think the app has great potential. iOS 15.8.3

Steve, Not feeling like a 'gotcha' - I just wanted to clarify the use of the tool... But after you messaged this I'm currently looking at unisons and how they're interpreted by software - the logic is tough! 

What i tested on my own piano (you folks who click the link are all the beta testers!) - I knocked an A4 unsion out of tune and left A3 and A5 clean - it registered a bad note, but because all three weren't bad, it gave a passing grade. if I knocked another the A3 unison out by roughly the amount of the # in the settings box, and it registered 2 out of 3 bad notes and got a provisional pass. 3/3 failures determines the messaging to the customer that yes - 3 notes across your piano are not right.

 As I spend time this evening looking at how to parse beating unisons through data, my head begins to hurt, haha!

Sean, actually my question is how well does it do if there's a 10-15 cent spread between the 3 strings of a unison? This isn't a gotcha question, I'm just curious.

My Verituner seems to do some sort of summing thing and gives inaccurate readings that don't reflect any of the strings. I know that there's an ETD that can differentiate, but as you say this isn't a tuning device. If the unisons are wildly out of tune can you still get the relative information you need?

Steve - thanks, I totally agree about different customers and technical abilities (or desires to even try). 

these are great questions and I'll be honest - precision isn't particularly the main goal of the app (I'm not writing a replacement for iRCT).

The math is logical for a simple single page of html - how far off of the fundamental pitches of ~220, 440, and 880 are the notes? I'm guessing that discerning technicians will find this app to be unsuitable for ~5c readings. However, for a first-touch customer who doesn't know what's happening with the piano, knowing it's 20-100c flat is easily detectable. 

I appreciate you looking into it!

Tremaine, I'm familiar with your work on Piano Scale - I'm honored you're participating in the conversation! The PTG is such an amazing resource… 

The entire app and logic are static html, no server calls or http requests. If you inspect the page, it's all there - the only call that saves data (on the tuner section) is a JavaScript helper to write your personal details to the cache on your local device (so the next time you open the link you don't have to type the details in again, just click copy).

My real goal is putting it into my own gazelle self scheduler and prompting customers to check before tuning. The first feedback as "I don't know what A4 means" - so I stripped out a lot of cool complexity and visual strobe tuner stuff - What's the most basic thing I need? A picture of a piano and audio samples across the midrange. We'll see how the next round of feedback comes in… 

Thanks for checking it out!

Sean, I think this is a good idea though it might work better with some customers than others. I'm wondering how it deals with really bad unisons? And alternately, if it could have a module the evaluates unisons as well?

Tremaine, I'm familiar with your work on Piano Scale - I'm honored you're participating in the conversation! The PTG is such an amazing resource… 

The entire app and logic are static html, no server calls or http requests. If you inspect the page, it's all there - the only call that saves data (on the tuner section) is a JavaScript helper to write your personal details to the cache on your local device (so the next time you open the link you don't have to type the details in again, just click copy).

My real goal is putting it into my own gazelle self scheduler and prompting customers to check before tuning. The first feedback as "I don't know what A4 means" - so I stripped out a lot of cool complexity and visual strobe tuner stuff - What's the most basic thing I need? A picture of a piano and audio samples across the midrange. We'll see how the next round of feedback comes in… 

Thanks for checking it out!

Sean, This is a very cool tool. I often get customers to play a note on their piano but sometimes the cell phone fidelity is hopeless. The only thing that might need clarification is whether our technician name and cell number is stored anywhere on the website or cloud.

Yes, and - the language is very specific - "your piano needs to be tuned, but doesn't need a pitch raise" (even if all 3 samples are "correct") 

the discerning customer isn't going to stop the thought process of needing to be tuned if the barrier for that tuning is a pitch raise or not. Not needing a pitch correction is a sigh of relief, in my opinion.

Hi Sean

Great work on the app. I like the concept!

One small thought: since pianos can sometimes be sharp, "pitch correction" or "pitch adjustment" might be more flexible than "pitch raise." Just a thought.

Hi piano friends, I've made another free piano technician tool! (Open to feedback and feature fixes).

https://pitchraise.app/index.html

This web-based app enables customers to be able to check if they need a pitch raise as part of the appointment setting process. This runs in the web browser so any modern phone, iOS or Android can use it.

There are no downloads, no cost, no ads, no sign up's - send the link to your customer and let them measure the piano themselves. It's pretty simple. If you have pre-set limits on pitch raises (some techs say -10, others say -20, etc) - ask the customer to open the settings and change the pitch field to YOUR value. 

For tuners - if you enter "0000" in this field a new window will display - you can enter your name or business name and phone number - this generates a link you can copy with a "Deep Link" - when they open the link it will say your name or company, ie. "Denver Piano Service would like you to measure your piano to see if a pitch raise or additional tuning is needed" 

When the customer completes the testing it generates a button to text the results back to you. 

🚨GO LAND MORE PITCH CORRECTION BILLING!! 🚨

(There's a Venmo link on the bottom of the page if you think you'll use this tool or it makes you more money, buy me a ☕️)

I'll give it a try today - maybe it would help to sound the note that should be played first? That might help someone to realize if they are playing the wrong note?

Peter - great observation, I am not personally tied to the A's - it feels like a cybertuner thing (especially how I go A4 -> A3 ->A5 … now that you've said it, that feels more like a tic in my head. 

Its not sampling stretch as RCT does, so the cleanest, easiest option for a customer is the only goal. 

I'm curious if others would prefer/agree - on the customer-facing side - is middle C the starting point?

Possible suggestion: more people know where (and what) "middle C" is, vs A4 or A-440. Just an observation.

Steve, Not feeling like a 'gotcha' - I just wanted to clarify the use of the tool... But after you messaged this I'm currently looking at unisons and how they're interpreted by software - the logic is tough! 

What i tested on my own piano (you folks who click the link are all the beta testers!) - I knocked an A4 unsion out of tune and left A3 and A5 clean - it registered a bad note, but because all three weren't bad, it gave a passing grade. if I knocked another the A3 unison out by roughly the amount of the # in the settings box, and it registered 2 out of 3 bad notes and got a provisional pass. 3/3 failures determines the messaging to the customer that yes - 3 notes across your piano are not right.

 As I spend time this evening looking at how to parse beating unisons through data, my head begins to hurt, haha!

Sean, actually my question is how well does it do if there's a 10-15 cent spread between the 3 strings of a unison? This isn't a gotcha question, I'm just curious.

My Verituner seems to do some sort of summing thing and gives inaccurate readings that don't reflect any of the strings. I know that there's an ETD that can differentiate, but as you say this isn't a tuning device. If the unisons are wildly out of tune can you still get the relative information you need?

Steve - thanks, I totally agree about different customers and technical abilities (or desires to even try). 

these are great questions and I'll be honest - precision isn't particularly the main goal of the app (I'm not writing a replacement for iRCT).

The math is logical for a simple single page of html - how far off of the fundamental pitches of ~220, 440, and 880 are the notes? I'm guessing that discerning technicians will find this app to be unsuitable for ~5c readings. However, for a first-touch customer who doesn't know what's happening with the piano, knowing it's 20-100c flat is easily detectable. 

I appreciate you looking into it!

Ron, I also wondered about "pitch Raise" and considered "pitch correction" which will add 5 characters of screen real estate.

If the pitch level exceeds the 10 cent threshold the return text indicates +-amount sharp or flat. 

I knocked A4 and A3 noticeably out with left string flat and right string sharp and A5 good and the sampling handled all three. Sean, if you worked on this good job. Otherwise I think it is pretty good grabbing a bad unisons

I have a few suggestions which will follow in another post.

This is a cool idea, I'd like to play around with it some later. Concerning the suggestions of the starting note, is it possible to program a full keyboard with lighted up notes or something?

I'll give it a try today - maybe it would help to sound the note that should be played first? That might help someone to realize if they are playing the wrong note?

Peter - great observation, I am not personally tied to the A's - it feels like a cybertuner thing (especially how I go A4 -> A3 ->A5 … now that you've said it, that feels more like a tic in my head. 

Its not sampling stretch as RCT does, so the cleanest, easiest option for a customer is the only goal. 

I'm curious if others would prefer/agree - on the customer-facing side - is middle C the starting point? 

Possible suggestion: more people know where (and what) "middle C" is, vs A4 or A-440. Just an observation.

Steve, Not feeling like a 'gotcha' - I just wanted to clarify the use of the tool... But after you messaged this I'm currently looking at unisons and how they're interpreted by software - the logic is tough! 

What i tested on my own piano (you folks who click the link are all the beta testers!) - I knocked an A4 unsion out of tune and left A3 and A5 clean - it registered a bad note, but because all three weren't bad, it gave a passing grade. if I knocked another the A3 unison out by roughly the amount of the # in the settings box, and it registered 2 out of 3 bad notes and got a provisional pass. 3/3 failures determines the messaging to the customer that yes - 3 notes across your piano are not right.

 As I spend time this evening looking at how to parse beating unisons through data, my head begins to hurt, haha!

Sean, actually my question is how well does it do if there's a 10-15 cent spread between the 3 strings of a unison? This isn't a gotcha question, I'm just curious.

My Verituner seems to do some sort of summing thing and gives inaccurate readings that don't reflect any of the strings. I know that there's an ETD that can differentiate, but as you say this isn't a tuning device. If the unisons are wildly out of tune can you still get the relative information you need?

Steve - thanks, I totally agree about different customers and technical abilities (or desires to even try). 

these are great questions and I'll be honest - precision isn't particularly the main goal of the app (I'm not writing a replacement for iRCT).

The math is logical for a simple single page of html - how far off of the fundamental pitches of ~220, 440, and 880 are the notes? I'm guessing that discerning technicians will find this app to be unsuitable for ~5c readings. However, for a first-touch customer who doesn't know what's happening with the piano, knowing it's 20-100c flat is easily detectable. 

I appreciate you looking into it!

Sean, I think this is a good idea though it might work better with some customers than others. I'm wondering how it deals with really bad unisons? And alternately, if it could have a module the evaluates unisons as well?

Tremaine, I'm familiar with your work on Piano Scale - I'm honored you're participating in the conversation! The PTG is such an amazing resource… 

The entire app and logic are static html, no server calls or http requests. If you inspect the page, it's all there - the only call that saves data (on the tuner section) is a JavaScript helper to write your personal details to the cache on your local device (so the next time you open the link you don't have to type the details in again, just click copy).

My real goal is putting it into my own gazelle self scheduler and prompting customers to check before tuning. The first feedback as "I don't know what A4 means" - so I stripped out a lot of cool complexity and visual strobe tuner stuff - What's the most basic thing I need? A picture of a piano and audio samples across the midrange. We'll see how the next round of feedback comes in… 

Thanks for checking it out!

Sean, This is a very cool tool. I often get customers to play a note on their piano but sometimes the cell phone fidelity is hopeless. The only thing that might need clarification is whether our technician name and cell number is stored anywhere on the website or cloud.

Yes, and - the language is very specific - "your piano needs to be tuned, but doesn't need a pitch raise" (even if all 3 samples are "correct") 

the discerning customer isn't going to stop the thought process of needing to be tuned if the barrier for that tuning is a pitch raise or not. Not needing a pitch correction is a sigh of relief, in my opinion.

Hi Sean

Great work on the app. I like the concept!

One small thought: since pianos can sometimes be sharp, "pitch correction" or "pitch adjustment" might be more flexible than "pitch raise." Just a thought.

Hi piano friends, I've made another free piano technician tool! (Open to feedback and feature fixes).

https://pitchraise.app/index.html

This web-based app enables customers to be able to check if they need a pitch raise as part of the appointment setting process. This runs in the web browser so any modern phone, iOS or Android can use it.

There are no downloads, no cost, no ads, no sign up's - send the link to your customer and let them measure the piano themselves. It's pretty simple. If you have pre-set limits on pitch raises (some techs say -10, others say -20, etc) - ask the customer to open the settings and change the pitch field to YOUR value. 

For tuners - if you enter "0000" in this field a new window will display - you can enter your name or business name and phone number - this generates a link you can copy with a "Deep Link" - when they open the link it will say your name or company, ie. "Denver Piano Service would like you to measure your piano to see if a pitch raise or additional tuning is needed" 

When the customer completes the testing it generates a button to text the results back to you.

I liked the simple, basic app.

When encountering a piano, I would do more than just play 3 notes before deciding how to tune. I would choose those notes as my impression of the piano developed and I formed questions about it. That is a professional skill and judgement, and I don't think a simple customer operated app could be absolutely certain. 

It is a primary test, and I think customers could understand this with the right evaluation phrase. "Based on this information..."

But it would be especially useful in the more extreme 5 -10-15 years since last tuned.

Ron, I also wondered about "pitch Raise" and considered "pitch correction" which will add 5 characters of screen real estate.

If the pitch level exceeds the 10 cent threshold the return text indicates +-amount sharp or flat.

Sean, Here is my pitchraise.app wish list:

Make the "A above Middle C" prompts same font and boldness as "Note 1 of 3 Play and hold" for each sampled note. I missed these prompts initially.

Change final screen to: Tap to Text result to Littleton Piano (add Tap - I originally missed that I was supposed to tap this button - I Did not realize it was a button)

Consider replacing the words Pitch Raise with Pitch Correction (screen space permitting)

I think I am probably more likely to make use of this with a single note Middle C option. Why not have both. So:

Add a line in the Technician Options Setup: Use 1 or 3 Test Notes [1] or [3] (or radio buttons/dropdown) and include one more parameter (&testnotes=1) passed in created the link

If testnotes = 3
  execute current  3 note screens for A's
else
  execute 1 note screen for Middle C
endif

Middle C Prompt like: The key below a black note and above a white note (space permitting)

"Based on this information . . ."  I like that. 

I liked the simple, basic app.

When encountering a piano, I would do more than just play 3 notes before deciding how to tune. I would choose those notes as my impression of the piano developed and I formed questions about it. That is a professional skill and judgement, and I don't think a simple customer operated app could be absolutely certain.

 As I spend time this evening looking at how to parse beating unisons through data, my head begins to hurt, haha!

Sean, actually my question is how well does it do if there's a 10-15 cent spread between the 3 strings of a unison? This isn't a gotcha question, I'm just curious.

My Verituner seems to do some sort of summing thing and gives inaccurate readings that don't reflect any of the strings. I know that there's an ETD that can differentiate, but as you say this isn't a tuning device. If the unisons are wildly out of tune can you still get the relative information you need?

Steve - thanks, I totally agree about different customers and technical abilities (or desires to even try). 

these are great questions and I'll be honest - precision isn't particularly the main goal of the app (I'm not writing a replacement for iRCT).

The math is logical for a simple single page of html - how far off of the fundamental pitches of ~220, 440, and 880 are the notes? I'm guessing that discerning technicians will find this app to be unsuitable for ~5c readings. However, for a first-touch customer who doesn't know what's happening with the piano, knowing it's 20-100c flat is easily detectable. 

I appreciate you looking into it!

Sean, I think this is a good idea though it might work better with some customers than others. I'm wondering how it deals with really bad unisons? And alternately, if it could have a module the evaluates unisons as well?

Tremaine, I'm familiar with your work on Piano Scale - I'm honored you're participating in the conversation! The PTG is such an amazing resource… 

The entire app and logic are static html, no server calls or http requests. If you inspect the page, it's all there - the only call that saves data (on the tuner section) is a JavaScript helper to write your personal details to the cache on your local device (so the next time you open the link you don't have to type the details in again, just click copy).

My real goal is putting it into my own gazelle self scheduler and prompting customers to check before tuning. The first feedback as "I don't know what A4 means" - so I stripped out a lot of cool complexity and visual strobe tuner stuff - What's the most basic thing I need? A picture of a piano and audio samples across the midrange. We'll see how the next round of feedback comes in… 

Thanks for checking it out!

Sean, This is a very cool tool. I often get customers to play a note on their piano but sometimes the cell phone fidelity is hopeless. The only thing that might need clarification is whether our technician name and cell number is stored anywhere on the website or cloud.

Yes, and - the language is very specific - "your piano needs to be tuned, but doesn't need a pitch raise" (even if all 3 samples are "correct") 

the discerning customer isn't going to stop the thought process of needing to be tuned if the barrier for that tuning is a pitch raise or not. Not needing a pitch correction is a sigh of relief, in my opinion.

I checked my piano. No pitch raise needed. I guess I'll put off the tuning since it's. It that bad.

Hi Sean

Great work on the app. I like the concept!

One small thought: since pianos can sometimes be sharp, "pitch correction" or "pitch adjustment" might be more flexible than "pitch raise." Just a thought.

Hi piano friends, I've made another free piano technician tool! (Open to feedback and feature fixes).

https://pitchraise.app/index.html

This web-based app enables customers to be able to check if they need a pitch raise as part of the appointment setting process. This runs in the web browser so any modern phone, iOS or Android can use it.

There are no downloads, no cost, no ads, no sign up's - send the link to your customer and let them measure the piano themselves. It's pretty simple. If you have pre-set limits on pitch raises (some techs say -10, others say -20, etc) - ask the customer to open the settings and change the pitch field to YOUR value. 

For tuners - if you enter "0000" in this field a new window will display - you can enter your name or business name and phone number - this generates a link you can copy with a "Deep Link" - when they open the link it will say your name or company, ie. "Denver Piano Service would like you to measure your piano to see if a pitch raise or additional tuning is needed" 

When the customer completes the testing it generates a button to text the results back to you. 

🚨GO LAND MORE PITCH CORRECTION BILLING!! 🚨

(There's a Venmo link on the bottom of the page if you think you'll use this tool or it makes you more money, buy me a ☕️)

Firstly, thank you all for your incredible feedback!

For anyone asking or finding this tool in the future - you can absolutely use it on websites or text it around!! 

• Removed all "pitch raise" messaging from the app, "correction" and "based on this check" are in, adding emphasis on a longer appointment window. The main thing now is the fact that the web URL is literally "pitchraise.app" - it was available 🤷‍♂️. If people are buyin' coffee - i can register a different domain name. I'm personally agnostic on "pitch raise" language.

• The tuner settings now provide options to choose between C's or A's and one note or three. 

• Updated language on the checking notes process for less-musical folk (with keyboard picture and identified note)
• • A4: "Find a group of THREE black keys near the middle of the piano. Press the white key between the last two black keys of that group."
  • C4: "Find a pair of TWO black keys near the middle of the piano. Press the white key just to the LEFT of those two black keys.
    
    
    

Keep the feedback coming, and thanks again!

Sean, Here is my pitchraise.app wish list:

Make the "A above Middle C" prompts same font and boldness as "Note 1 of 3 Play and hold" for each sampled note. I missed these prompts initially.

Change final screen to: Tap to Text result to Littleton Piano (add Tap - I originally missed that I was supposed to tap this button - I Did not realize it was a button)

Consider replacing the words Pitch Raise with Pitch Correction (screen space permitting)

I think I am probably more likely to make use of this with a single note Middle C option. Why not have both. So:

Add a line in the Technician Options Setup: Use 1 or 3 Test Notes [1] or [3] (or radio buttons/dropdown) and include one more parameter (&testnotes=1) passed in created the link

If testnotes = 3
  execute current  3 note screens for A's
else
  execute 1 note screen for Middle C
endif

Middle C Prompt like: The key below a black note and above a white note (space permitting)

"Based on this information . . ."  I like that. 

I liked the simple, basic app.

When encountering a piano, I would do more than just play 3 notes before deciding how to tune. I would choose those notes as my impression of the piano developed and I formed questions about it. That is a professional skill and judgement, and I don't think a simple customer operated app could be absolutely certain. 

It is a primary test, and I think customers could understand this with the right evaluation phrase. "Based on this information..."

But it would be especially useful in the more extreme 5 -10-15 years since last tuned.

Ron, I also wondered about "pitch Raise" and considered "pitch correction" which will add 5 characters of screen real estate.

If the pitch level exceeds the 10 cent threshold the return text indicates +-amount sharp or flat. 

I knocked A4 and A3 noticeably out with left string flat and right string sharp and A5 good and the sampling handled all three. Sean, if you worked on this good job. Otherwise I think it is pretty good grabbing a bad unisons

I have a few suggestions which will follow in another post.

This is a cool idea, I'd like to play around with it some later. Concerning the suggestions of the starting note, is it possible to program a full keyboard with lighted up notes or something?

I'll give it a try today - maybe it would help to sound the note that should be played first? That might help someone to realize if they are playing the wrong note?

Peter - great observation, I am not personally tied to the A's - it feels like a cybertuner thing (especially how I go A4 -> A3 ->A5 … now that you've said it, that feels more like a tic in my head. 

Its not sampling stretch as RCT does, so the cleanest, easiest option for a customer is the only goal. 

I'm curious if others would prefer/agree - on the customer-facing side - is middle C the starting point? 

Possible suggestion: more people know where (and what) "middle C" is, vs A4 or A-440. Just an observation.
