15 Hz – B – chromatic

B is a meeting of (almost) all keys of the 12 reference frequencies. An “overtone” in which they are all gathered together:
256, 270, 288,300,320,352,360,384,400,432,450,480 HZ.

In general, a ratio of 45/32 is assumed for the augmented fourth. This would be an F in the key of B, but then has a frequency of 337.5, which also sounds good in chromaticism.
With a ratio of 22/15, the tone F has a frequency of 352 Hz. If the augmented fourth has a ratio of 45/32, then the reference frequency for the F octave tone row is omitted.
But still: 11 keys are always present. That is unique.
