User:BudjarnLambeth/Substitute harmonic

A substitute harmonic is a more complex harmonic which is used to substitute for a simpler one.

For example, you could substitute the 3rd harmonic for the very similar 769th harmonic. By doing this, you could convert a 2.3.5 subgroup temperament into a 2.769.5 subgroup temperament. Or, you could convert a 3.5.7 combination product set into a 769.5.7 combination product set. The possibilities are vast.

Why do this? It could allow for a whole array of subtly different harmonic flavours of existing tunings, while preserving their broader melodic and harmonic structure.
