Figure 1.b Comparison Tone frequencies (in Hz) of (a) the Equal Temperament Scale and (b) the Scale of Twelve Fifths for concert pitch A=440Hz, A=432Hz
The A440 Equal Temperament Scale also shares sacred geometric harmonic ratios in their whole number derivations. For the diatonic notes:
C, D, E, F, G, A, B, C, the harmonic ratios are:
1, 9/8, 81/64, 4/3, 3/2, 27/16, 2, for both tunings.
In A = 432 Hz as a tuning, harmonic intervals are shown, revealing primary sacred geometric relationships like the square root of two.
That the overall harmony and pleasing consonance revealed in the sacred geometric ratios across the scale tuned to 432 Hz may be one reason why this tuning creates an overall positive healing effect on the listener and seeker of healing.
