<<<<<<<<<<<<<<<<<<<<< To the tuning list, As I told you, I cannot check what kind of chords produces the second scale derived from an array of squares that I give you below because I don't have a tone adjustable instrument. However, in this case I presume that they are reasonable good. The following data show good features to me: -- Seven perfect fifths plus five fifths that are close to 1.5 -- Eleven major thirds with suitable values (403.4, 396, 397.2, 400.4), plus F major fifth with 406.5 cents which might cause beating. -- Tone intervals sequence: C#/C --101.95 cents D/C# -- 100.7 Eb /D -- 99.7 E/Eb -- 101.95 F/E --- 94.6 F#/F -- 101.95 G/F# -- 101.95 Ab /G -- 101.95 A/Ab -- 100.7 Bb/A -- 99.7 B/Bb -- 101.95 2C/B -- 94.6
------------------ FIFTHS G/C -- 1.5 Ab/C# -- 1.5 A/D -- 1.5 Bb/Eb -- 1.5 B/E -- 1.5 2C/F -- 1.5 2C# /F# -- 1.5 1.4989..... 1.496..... 1.497..... 1.49..... 1.49.....

<<<<<<<<<<<<<<<<<<<<<<<< I hope one of you can test and evaluate this scale and send me the results Mario Lima, May 20, 2011
