>>11427700Are you trying to tell me that the harmonic series of overtones does not occur on a piano? What are you talking about? Every single acoustic instrument has overtones, even a xylophone. It is a product of the physical universe, bud. It goes like this: begins with an octave, followed by a 5th, and then up to next octave, then M3rd, the 5th again, and then b7. Then go up to next octave, the 9th, major 3rd, #11, 5th, 13, b7, major 7, and finally another octave. This is the natural overtone series whether you like it or not, and our 12 tone equal temperament is based entirely around trying to approximate it best:

That’s the only one. There are waveforms that have overtones that are not modeled after the harmonic series order of intervals that occurs in our physical universe, but they still have overtones, usually in a pattern. A saw wave has all integer harmonics whereas a square only has odd integer harmonics. Some synths let you draw in overtones and adjust each one like a mixer, but it’s always the same principle: a fundamental and its overtones (except for sine wave only)
