>>11499854>Add in electrical amplification and you have a plethora of circuit analysis and signal processing.That is electronics, not music.
>Sound alone can be described as a complex waveform propagating through some medium.This is irrelevant for any musical property. To illustrate how waveforms are disconnected from musically meaningful properties: One can invert the polarity of a recording, play it back, and no appreciable distortion results.
