The other day I did a tuning of potential interest for a number of reasons and of course the video is very boring. Please forgive that. But it's there for anyone to take away from it what they want, even if it's how not to tune an instrument!
- High noise environment with cooling fan continuously, street noise and passing traffic, motorbikes roaring, people talking https://youtu.be/7rwP1TGhUps?t=4114
- Stability over a year even despite high temperature variations.
- Failure to account for Weinrich flattening and getting things right for the wrong reasons. https://youtu.be/7rwP1TGhUps?t=1024 I have half an idea why this is leading me to get good tunings in unequal temperament - although listening to the video I might have been more exact on a unison or two. Apologies. This isn't my best tuning in the best of conditions
- Bass ghosting https://youtu.be/7rwP1TGhUps?t=1616
- Tuning the 4th string aliquot. Mathematical doubling of pitch or matching 1st partial? https://youtu.be/7rwP1TGhUps?t=351
In relation to the aliquot string - it's a hideously impure note. If we tune to mathematical doubling might it nudge the 2nd partial of the struck string to be more harmonic? Or if we tune it to the 2nd partial does it absorb the inharmonic energy of the partial and make the note sound sweeter?
For anyone thinking of spending a lot of money on a pickup device to tune in high ambient noise environments perhaps watching the video might give a better idea as to whether a pickup device or any fancy microphone is worth the money. This ETD has brilliant discrimination against noise because it works on the basis of an oscilloscope. With a Scope the timebase frequency governs the speed at which the electron beam runs across the screen. The signal is then visible against that and it's very simple. The amplitude of the piano wave is represented by the brightness of the LED dots so that one can see nuances of harmonics on the wave if inharmonic and even to the extent here that I was able to tune the aliquot without the machine having to change to different note.
My approach to tuning, as can be seen, is cringeworthily rough and ready but the proof of the pudding is in the eating and my concert tunings, as anyone who's listened to my concert recordings on YouTube know, work rather well.
It's encouraging to have found even well respected and known PTG members on YouTube now questioning Equal Temperament and the OCD mindset of super-perfection of the deliberately all-at-sea nature of ET vibrations.
Greetings from Greece and best wishes,
