Richard, my sustains are about 2 sec per attack. That is more than enough. Kent Swafford liked the demo and gave me the feedback before I made the SoundCloud posting. I also played for 4 pro tuners in my house on my Fazioli F308 and every single one of them said it was the best and most in-tune piano they have EVER heard. Every one of them were late-60's early 70's age and all had 30+ years of pro tuning. One of them said that my piano virtually sounded 'inhuman' and 'beat-less' on the 5ths, octaves, 12ths. --- Steve

Mr. Roberts contrasts recently tuned WT and ET by demoing chromatic 3rds so you can hear the effect/contrast of what's going on in both temperament styles more easily. He also discusses the 5ths. He seems open to exploring UT more in the future. Perhaps David P. did this tuning?
Steve Norsworthy's demo of the P12 is played so fast I don't really hear or appreciate it as much as I should.
I'm well familiar with the P12, since I adopted it
when Mr. Stopper first introduced it or early on,
anyhow. There was much discussion and buzz about it
at that time.
As regards Franz Mohr, from discussion here in the past, I believe it was claimed that he once stated that he didn't stretch the treble much. I'm pretty sure he was an aural tuner and did not rely on ETDs. I'm familiar
with his work through recordings and live performances.
I would not call his tunings sound the same as what we're hearing with P12.
There is one video of him tempering
4ths vs 5ths as advocated by Steinway.
I'm following this discussion and will begin using
the new mic I purchased soon. I appreciate all the
good points made by each and every tuner commenting.

>>Ed and Dennis,
ANY temperament can be described as a weighted linear equation of various ratios of partials.
Steve<<
Of course they can, just as facial recognition software proves that any face on this planet can be described by a chunk of computer code. However, no program is able to tell if that face will be seen as beautiful or ugly. While the scientist may find some attraction to a set of numbers, what the music listener hears is described by something else.
The pursuit of a mathematical description of an unequal temperament, (which is a far more complex arrangement of the intervals than ET), is perhaps of interest to the scientist, but is a useless endeavor to the tuner that is tailoring it to the pianist that wants it. And the ability of one tuner to transmit the information to another tuner so that a particular unequal tuning can be replicated is a fairly simple matter. Perhaps there would be a fraction of a cent difference, but that easily falls below the 'just noticeable threshold" that human perception is capable of, so I submit it is a moot consideration.
Even if you have the numbers for a 'perfect' equal temperament, down to the .1 cent tolerance, that is of little import to the actual production of that tuning, as pianos' overall stress changes as the strings' tension is changed, as well as the fact that pianos 'breathe' on a continual basis, even in closely held environrments. To attempt clinical perfection on a concert stage where lights change, audiences change, and HVAC systems change is a doomed effort, so the perfection that a numerical description might indicate isn't really what one will end up with, regardless of effort.

Not intuitive, esthetic. And, it is easily 'cloned' with today's advanced ETD's. There is certainly no mathematical foundation to the beauty of musical expression as the contrast of a triad with an 18 cent third resolving into a triad with an 8 cent third creates a musical result that cares not a whit about math, instead, relying on the listeners emotional response to determine the value of the change.
Our brains evolved with an exquisite ability to detect and respond to varying levels of dissonance as a survival skill. That particular circuitry goes to sleep when the level of dissonance is unchanging. There are many studies of the psycho-emotive response that show that we respond to varying levels of consonance with corresponding levels of engagement. How this applies to musical composition is familiar to those of us that have employed a variety of tuning styles and listened to our customer's feedback.
"never, superiority, totally, fundamental", all extreme words indicating a desire to make a black and white straw argument. Steve, do you tune? Have you any practical experience with the various systems? Have you worked with artists in these systems ?

Greetings,
The stretch, in my use, affects the octaves' relationships. It doesn't change the effects of temperament, other than increasing the stretch increases the speed of the thirds. What is more germane is that the more highly tempered thirds of a UT will be more consonant farther down the keyboard than those in ET, as there is the consideration of the critical band being wider, which allows a lower limit to acceptable dissonance.
The major difference in musical effect of a UT diminishes as one goes above the fifth octave, as we do not hear the beat rate speeds the same as when they are produced in the middle of the keyboard. Once past 15 BPS we don't hear it as tempering, anymore. However, there can be distinct differences in the sound of a 17th or greater, as the more highly tempered keys will often produce a beating that is no unlike an operatic voice with coloratura.
It is difficult to transmit much useful information intellectually when the subject is sensual in nature. All the words in the world will not tell a person what a banana tastes like if they have never tasted one. All the history and logic in the world will not teach a person what the different interpretation of a Beethoven sonata in a Young temperament feels like. It has to be experienced. It is for this reason I don't hold that one or another temperament is superior, but never investigating the various ways to tune a piano is a recipe for a limited appreciation of any of them. Perfect science doesn't automatically mean perfected art.

Many modern compositions are damage-free when performed on a tuning that contains a palette of tonal resources. The loss of perfect equality isn't even discernible (except to the tuners in the audience), while reinforcing the harmonic contrasts in the Classical compositions. In my years a the university, the well-tempered D on stage was chosen more often than the ET one. Even though I switched the tuning from one to the other to remove any influence the individual piano might exert, the Victorian tuning was the one that spoke to the majority of visiting pianists. (No one was ever told that the pianos were in different temperaments, so these were blind choices) >>Some may disagree and wish we harkened back to the late 18th century way of tuning unequal temperament. It becomes an emotional argument with them and all I can say is they have the right to like this but it is not the main stream for today. Many of us harken back to the mid 19th century's style of tuning, which alters the thirds by a very small amount that gives a coloration to the keys. I think it is fallacy to believe that anything other that 'perfectly equal' is restrictive, as numerous performances have shown. Equal temperament has its place as a great resource for convenience, however, it does the same thing to harmony that a click track does to tempo; it makes it perfectly even, easy to synchronize, universal, and often boring to those that expect music to breathe. There is nothing magical about the sound of a 14 cent third, and many pianists who have developed a recognition of the alternatives find the complete regularity of equal temperament to be stultifying. For them, music is an emotional event, and a temperament that offers a variety of emotional stimulation (thirds) makes for a deeper emotional response when listening. Regards, Regards, |

Hi Dennis,
If we simply use the Pure12th method as taught by Kent Swafford, then we get the perfect balance between the 5ths at -1.2347¢ and the octaves at +1.2347¢ and then the 3rds take care of themselves automatically. We cannot independently adjust the 5ths, octaves, and 3rds. They are all interdependent. That simply does not work mathematically. However, I am 'yet' to hear anyone say that Pure12th tuning is anything but musically spectacular from a subjective point of view. It provides a special clarity or bell-like sound from being so consonant.
'Equal' means that there is absolutely no bias for any key. 'Tuning Is Math', one of my slogans that says that anything we do to tune an instrument can be described by a mathematical relationship between the notes. If we tune intuitively, it is not duplicatable and requires us to be cloned as human beings! A little humor to make the point.
Furthermore, the 'high tech' tools allow us to have a nearly 'perfect' implementation that we humans cannot quite achieve, so we don't have to clone ourselves to have others achieve the same great result. That is the breakthrough of high-tech tuning that was not previously available. One of the top aural tuners in the country is a friend of mine, and I told him that we no longer need to clone him (LOL) because we can apply modern high-tech apps and sensors and make a piano sound better in tune than we could even dream of in the past aurally. He did not particularly 'like' that but could not refute it either, especially when I demonstrated it with the most up-to-date advanced app and sensor.
The turn of the 20th Century led to the end of traditional 'tonality' as we knew it in Western Classical Musical Traditions, requiring us to be more 'equal' in our treatment of the notes, ending the notion of key signatures. Subjectively speaking now, a concert pianist has to play a wide variety of material on a program and needs this 'equality' to pull it off. Some may disagree and wish we harkened back to the late 18th century way of tuning unequal temperament.

Steve-
I appreciate your enthusiasm and agree that the P12 tuning style works nicely, especially for ET. No argument, however I think we can agree it is the 3rd that provide color, and that is also an important part of our musicological history. It doesn't have to be either/or. One thing that wasn't mentioned is that P5ths also imply equal beating triads, which is part of the improved clarity. However, if we blend that with a subtle variety of color, which is consistent with compositional styles of the majority of music people play on the piano, then in my opinion it takes the whole experience to a even higher musical experience. It's not good or bad though, it's all good. The reason I got away from P12 tuning is because it can stretch the 10ths in black keys a little more than my comfort level.
thanks,
Dennis.

Fred,
I would call myself a 'disciple' of Kent Swafford. We talk nearly every week. He 'converted' me to the Pure 12th. I can really hear the difference using it. Kent listened to my recordings after tuning and really approved of what it achieved. Pianoscope's IH and tuning curves are what I use, along with the sensor of course. That combination nails the 12th so well that it sounds 'hollow' and totally beat-less. The rest of the piano sings with a bell-like clarity that it never did before. Kent and I looked at my tuning curves in Pianoscope. We jointly determined that due to the extremely low IH of this Fazioli, that it was the ideal candidate for the 3:1 only, and set the curve to 3:1, and turned off the 6:2 and 9:3, and it was a wise choice. My 3:1 is nearly perfectly flat.
Thanks for the references.
I think some on the PTG who read my essay will appreciate the motive of offering a musicology perspective. Most tuners don't have formal music education and degrees. I have gotten to know now about 100 tuners in the past 6 months. Only one has a Masters Degree in Keyboard and is an active performer. I love to teach, it was my 'calling' from a young age. I do not mean to 'talk down' to anyone with the essay. I hope it added perspective to those who have not thought as much about the musicology of pitch perception in music history.
Best and kind regards,
Steve

A guy named Jean-Jacques Rameau wrote much the same thing back in 1722 in his
Traité de l'Harmonie, Reduit a ses Principes Naturels, ranking the intervals Unison, Octave, Fifth and Fourth, Third and Sixth, and deducing that they should have the same order of precedence as to their purity (hence advocating for ET, defined as a circle of fifths, each of which is slightly narrowed to the same degree).
Later tuners of stringed instruments, wanting to make their fifths more precisely equal in size, added listening to thirds, sixths, and various chords to the tuning process (
Claude Montal was prominent among them).
In March 1982, Gary Shulze wrote an article (Influences of Inharmonicity on Aural Tests in Equal Temperament) describing both 3:1 and 6:1 (ie, perfect twelfth and perfect 19th) tuning as an approach that balanced inharmonicity and stretch very well. He gave preference to 6:1. [His name was misspelled Schulze in the Journal, hence appears that way in the Journal Index).
In 2006, Bernhard Stopper began writing publicly in English about perfect 12th tuning (he wrote me that he had first published the ideas in 1988, trademarking "StopperStimmung"). He later developed a software program (Tunic OnlyPure) as a means to achieve that tuning by electronic means. He promised publication of data showing why perfect 12th tuning was clearly superior, but, as far as I know, never followed through. (He also described his "perfect 12th" as "sweet-spotted," which he clarified, in my discussion with him, as somewhat wide, balancing 3:1, 6:2, 9:3).
In 2017-2018, Kent Swafford published a series of 14 articles on the subject of Twenty-First Century Style, in the course of which he described in great detail the perfect 12 temperament style.
This may help readers in establishing the historical precedence of some of these tuning ideas :-)

IT'S ALL ABOUT THE PERFECT 5th: A Musicological Perspective
I am writing this little essay 'for piano tuners' but 'from the perspective of a musicologist.' Let's talk about what is actually important in music regarding the intervals we use and how we tune.
Overall, perfect fifths are fundamental to the structure and sound of Western music, playing a key role in harmony, chord construction, tuning systems, tonal relationships, and overall musical expression.
The intervals of the octave and the perfect fifth have remained the two most important building blocks in Western music; the octave providing the framework of stability and repetition; and the fifth, generating the primary harmonic driving force, the dominant to tonic cadence.
The 'perfect fifth' is more consonant (consonance vs. dissonance), or stable, than any other interval except the unison and the octave. In some sense, it is even more important than the octave, which I will explain. It occurs above the root of all major (and minor) chords (triads) and their extensions. Until the late 19th century, it was often referred to by one of its Greek name, diapente. Its inversion is the perfect fourth. The octave of the fifth is the twelfth, hence, the 'Pure-12th Piano Tuning' achieves the musical goal of a 'Perfect 5th.' Violina, violas, and cellos are tuned in 5ths. The 'Circle of 5ths' is a fundamental concept. So, it wasn't by accident that the first steps towards harmony in Western music, started with the first intervals of the overtone series. The early polyphony of the middle ages consisted in one or more voice parts accompanying the cantus firmus, often in parallel motion using the interval of the octave, fifth or fourth (the first intervals found in the overtone series).
Harmony: Perfect fifths are considered one of the most consonant intervals in music. When two notes are played a perfect fifth apart, they sound pleasing and stable to the ear. This stability forms the foundation of harmony in Western music.
Chord Building: Perfect fifths are essential for building chords. In traditional Western music theory, chords are often constructed by stacking notes in intervals of a third (major or minor). The perfect fifth is a common interval found in many chords, such as the power chord (used in rock music) and the perfect fifth interval itself forms the basis of the dominant triad in tonal music.
Tuning Systems: Perfect fifths are crucial in tuning systems. In the context of equal temperament tuning (the tuning system commonly used in Western music), the perfect fifth is the interval that is tempered or adjusted to allow all keys to be played equally well. This compromise is necessary to ensure that music can be played in all keys without sounding out of tune.
Functional Harmony: In tonal music, the perfect fifth plays a significant role in establishing tonal centers and creating harmonic tension and resolution. For example, the perfect fifth relationship between the tonic and dominant is fundamental in establishing tonality and creating a sense of resolution when moving from the dominant back to the tonic.
Melodic and Harmonic Context: Perfect fifths are prevalent in melodies and harmonies across various musical genres. They provide a sense of stability, direction, and resolution, contributing to the overall structure and coherence of musical compositions.
On a personal note, in my early years as an orchestral trombonist, it was obvious trombone section's importance included providing underlying support chords. Three trombones can provide a triad chord. The section member who had the 5th had to be 'perfect', even more so than the member who had the 3rd, since half the literature is in a minor key.
Now, let's look at the math. An octave-based equal temperament puts the 5th at
2^(7/12) = 1.4983,
where the perfect 5th is 1.5.
Therefore, the 5th is 1.955 ¢ flat, since
1200*log2(1.4983 / 1.5) = -1.955 ¢ or nearly 2 cents flat.
Now let's examine the 5th using the 'Pure 12th System'
3^(7/19) = 1.4989
1200*log2(1.4989 / 1.5) = -1.2347 ¢
Therefore, 1.955 – 1.2347 = 0.7203 ¢, or in other words, the Pure 12th System produced a 5th that is ¾ ¢ better to being a perfect 5th. But, more importantly, it produces a Perfect 12th, so that 5th above the octave IS A PERFECT 5th!
Now ask yourself, why would a piano tuner, from a musicological perspective, want to even consider tuning using 3rds, 10ths, 17ths and counting beats from these 3rds? Yes, historically, it is easier to 'count beats' of progressive 3rds, but we now have 'new technology' that eliminates the need for this. The musicologist is telling us about the fundamental importance of the Perfect 5th! We now can achieve it with the 12th!
