A harmonic spectrum is a spectrum containing only frequency components whose frequencies are whole number multiples of the fundamental frequency; such frequencies are known as harmonics. "The individual partials are not heard separately but are blended together by the ear into a single tone." In other words, if ω {\displaystyle \omega } is the fundamental frequency, then a harmonic spectrum has the form { … , − 2 ω , − ω , 0 , ω , 2 ω , … } .
