I can't find any evidence to suggest that the numerical similarity is anything other than coincidence. On a related note, I sort of understand why the chromatic scale divides the range between 220 Hz and 440 Hz into 12 equal parts. Its one of the easiest scales to play and often will sound good with notes played in any order, as there are no half step (semitone) intervals in it which can cause dissonance. John Sloboda, a professor of music psychology at the Guildhall School of Music and Drama, explained that the tritone is particularly unnerving because the human brain is hardwired to find harmony and symmetry in music: When we hear something dissonant, it gives you a little bit of an emotional frisson, because it's strange and unexpected. or 12?

Youll commonly hear it used in all sorts of music genres in anything from classical, pop, jazz, and even heavy metal. This is a case where, because of the largeness of the numbers, none but a temperament-perverted ear could possibly prefer 45/32 to a small-number interval of about the same width. This is just a historical convention for naming musical intervals, which sort of originated by counting both endpoints in an interval. C-D-E-F-G-A-C: Andreas Werckmeister cites this term in 1702 as being used by "the old authorities" for both the tritone and for the clash between chromatically related tones such as F and F,[23] and five years later likewise calls "diabolus in musica" the opposition of "square" and "round" B (B and B, respectively) because these notes represent the juxtaposition of "mi contra fa". In the key of A, this would be A, C, D, E, and G. As you can see, its very similar to the natural minor scale but doesnt contain the 2nd and 6th degrees of the scale.

The pentatonic scale is used widely in a lot of different music genres. Early Indian Rig Vedic hymns were tri-tonic, sung in three pitches with no octave: Udatta, Anudatta, and Swarita. At any rate, avoidance of the interval for musical reasons has a long history, stretching back to the parallel organum of the Musica Enchiriadis. So, there are four notes per octave in all tetratonic scales. So the ratio 3:2 between frequencies sounds good (and, as noted, creates an interval called a perfect fifth), as well as the ratio 4:3 (the so-called perfect fourth). a) the 12 tones developed by the 7 fifths by Pythagoras.

Some composers flattened the B until it was a perfect fifth below the F, and others sharpened the F until it was a perfect fifth above the B, giving us our first two accidentals B flat and F sharp. However, in the above-mentioned naming convention, they are considered different notes, as they are written on different staff positions and have different diatonic functions within music theory. F sharp and B flat were the first ones, and they were invented to try and solve the problem of the tritone in music. But no, in the ancient Greek tunings, those smaller intervals are not exactly half the larger "whole tones." Containing tritones, these scales are tritonic. The dominant seventh chord in root position contains a diminished fifth (tritone) within its pitch construction: it occurs between the third and seventh above the root. (As I noted in comments, this overall can be thought of as a 12:9:8:6 ratio between four notes, which was how the Pythagoreans thought of it.).
