A geometrical waveform having a curve defined by the function y= sin x. In theory there are no other partials present and it can therefore be considered as the basic component from which (by combination) all other waveforms are made. It is the basic building block of all sound. Sometimes used quite incorrectly to describe pure tones irrespective of waveform. See also See also Pulse Wave, Ramp Wave, Square Wave, Triangle Wave.
