    I've been using the offsets for your Well Temperament and I've found it to be a smooth or maybe beat canceling effect. Seems to me it works especially well on spinets that need some calming down since they tend to be too bright and have high inharmonicity. I like it! What would the offsets be for your Final Temperament?

    Scott - thanks so much - this is really helpful and great news as it's what my harmonic analysis predicted. It's great to have verification of both Roshan's work and of my harmonic analysis methodology.

    I told Roshan that really we need to test his temperament on a really good instrument but your confirmation that it's helpful even to small instruments us brilliant.

    Best wishes

    David - I have used it on a couple nice Yamaha C2 grands and an older Yamaha C7 and I really liked the effect on them too. The C7 is in a chapel and they've really wanted to mellow or dampen the sound (someone before me voiced the hammers down) so this temperament will help with that issue. 
    It's interesting to see it on a tuning curve. In PianoMeter (formerly Easy Piano Tuner) the curve is right there and, as you'd expect, it makes it look like a sawtooth, so when I first used it I was surprised that it had a calming effect and not a brightening effect.

    Thank you very much for confirming this, Scott!

    My Well Temperament is available here for anybody that is interested in using it:

    "It is a modern well temperament rather than a traditional well temperament."

    What definition are you using for "modern well temperament", please?

    I must confess that when I tried out the temperament I wasn't sure what to expect. Not being a total aural tuner sometimes I don't trust my perceptions of how a tuning does or should sound. I mean, I know what I like and as I play a piano after I've tuned it I hear octaves and unisons that are off and I get a general idea of what's going on but this experience has given me more confidence that I can trust my ear.

    I just charted this "final" temperament, and it is a true well temperament very much like (and between) the Coleman 11 and Coleman 16. Traditional key color will show in this temperament. http://www.rollingball.com/images/Kakiya-Final.gif

    Scott,

    I have added the offsets in cents from 12-TET for my Final Temperament in my original post.

    My Final Temperament makes a variety of key colours available. Additionally, as shown on the image in my original post, its Circle of Fifths is symmetrical around C-G and Gb-Db.

    "My Final Temperament makes a variety of key colours available. Additionally, as shown on the image in my original post, its Circle of Fifths is symmetrical around C-G and Gb-Db."

    Isn't well temperament about the creation and placement of mildly tempered M3rds? Hasn't well temperament generally been arranged for the slowest-beating M3rds to be C-E?

    Your temperament's slowest M3rds are A#-D and F-A.

    Wouldn't it be better (and easily accomplished) to shift the temperament to arrange the slowest M3rds to be C-E and G-B?
