Original Wikitext content:
**Harmonics** are the basic building blocks of periodic sounds. They may also be referred to as partials or overtones, but these words can have different meanings in the same context. //Harmonic// usually refers to the sine wave components which make up a sound, which are whole-number multiples of the fundamental frequency (lowest tone). //Overtones// consist of all harmonics except for the fundamental; thus the 1st overtone is actually the 2nd harmonic, and so on. Unlike harmonics, //Partials// do not need to be related by whole-number multiples, but may instead be completely inharmonic. Harmonic oscillators such as a bowed violin or the human voice contains a nearly-infinite amount of harmonics, starting with 1f, 2f, 3f, 4f... where f is the fundamental frequency. Each of these harmonics has a distinct amplitude, generally decreasing as the 'height' of the harmonic increases. The span between any two of these harmonics is called a [[Gallery of Just Intervals|just interval]]. The ancient Greeks called these harmonics "multiples," and considered them to be a unique interval class separate from [[superparticular]] and [[Superpartient|superpartient]] intervals. http://en.wikipedia.org/wiki/Harmonic
