Artificial Harmonics - Compound
Introduction
Compound artificial harmonics are achieved much in the same way as regular artificial harmonics but with the addition of another node point place exactly midway between the node and the fundamental.
The effect of this is that the number to which the pitch relates on the relevant harmonic series is doubled, for example: if the original partial was the fourth, then the addition of the midway node point results in the 8th partial.
Compound Artificial harmonics using the fifth partial are not given here as the same pitch can be produced using a minor 3rd partial.
Notation
The notation of compound artificial harmonics presents a problem as the middle node point is often at a point which would require microtonal notation and becomes convoluted when using 3rd partial harmonics. I have therefore suggested the following notation to clarify that the pitch is a compound artificial harmonic:
4th Major 3rd Minor 3rd
