24 Tone: Also know as the quarter-tone scale, this scale
is used for variety but has no advantage in terms of
ratios that better approximate pure intervals.
31 Tone: In addition to intervals that better
approximate pure intervals, this scale also contains
good approximations to Indonesian pelog and slendro
scales.
53 Tone: Related mathematically to the cycle of fifths,
the 53-tone scale has very pure major and minor thirds,
and fifths and fourths.
Partch: Harry Partch is considered the father of modern
microtonality. This scale was devised by him and used in
instrument building and performances.
Carlos Alpha: Wendy Carlos performed extensive
computer analysis to devise a number of equal-tempered
scales with good approximations for the primary
harmonic intervals and their inversions. This scale is
good at approximating the primary intervals including
7/4. This scale divides the octave into 15.385 steps,
forming intervals of 78.0 cents.
Carlos Beta: This scale divides the octave into 18.809
steps, forming intervals of 63.8 cents.
Carlos Gamma: This scale achieves perfect purity of the
primary intervals 3/2, 4/3 and 5/4. This scale divides
the octave into 34.188 steps, forming intervals of 35.1
cents.
Harmonic (chromatic): This twelve-tone scale is
created in the partials in the fifth octave of the harmonic
series. The scale degrees that correspond to the classic
Just intervals are the major second, major third, perfect
fifth, and major seventh.
