Harmonic

A concentration of sound wave energy that relates to a fundamental frequency.

A Sine WaveThe purest of sounds, looking like a sequence of hills and troughs, the sine wave (or sinusoid) creates the sound of a single frequency with no harmonics or interference.More infoSine Wave is a simple sound and a concentration of soundwave energy at a single frequency.

Harmonic sounds are made up of a number of sine wave type components, making a complex sound. If the individual sine wave components within a single sound are related to one another by simple mathematics (whole number multiples of a fundamental frequency (f), for example: f2, f3, f4, f5,) they can be described as having a harmonic relationship. The root of this harmonic relationship is called the fundamental frequency.
