Harmonics

Harmonics are components of a periodic waveform at whole-number multiples of its fundamental frequency. The second harmonic is at twice that frequency and the third at three times it.

An exactly repeated single-cycle waveform contains harmonic components. A sawtooth's harmonic amplitudes fall roughly as 1/n, while a square wave contains odd harmonics. Changing the harmonic amplitudes across frames changes the table's timbre.
