Re: From Pianos to Amps

Compressive third harmonic is when the 3 rd harmonic is phased to REDUCE the amplitude of the top of the sine wave. This is the normal third harmonic generated by analog tape compression, etc. Expansive third can actually cancel compressive 3'rd, so it is interesting for this reason. It is more difficult to generate. Thanks for the input on the piano, and good reading of that 2/3 of a century old book that I recommended. I think that you will like it.
