This is a collection of tracks from different albums that are not released on Bandcamp.
432 Hz is part of a higher-level tuning system:
This tuning system is based on the basic reference frequency of
1 Hz (128 Hz).
This is the key of C.
And this is the origin of the 432 Hz music.
432 Hz frequency is unique.
If you build the pure tuning on the 432 Hz frequency, not only all octaves result in the cross sum 9, but also every note of the chromatic 12 scale.
There is no other scale that has this property.
