Harmonics are the geometric multiples created by the vibration of a specific object.

In acoustics and telecommunication, the harmonic of a wave is a component frequency of the signal that is an integer multiple of the fundamental frequency.
Sample for a harmonic series:

1f 440 Hz fundamental frequency first harmonic
2f 880 Hz first overtone second harmonic
3f 1320 Hz second overtone third harmonic

Harmonic – A sinusoidal quantity having a frequency that is an integral multiple of the frequency of a periodic quantity to which its related. A harmonic series of sounds is one in which the basic frequency of each sound is an integral multiple of some fundamental frequency (halves, thirds, fourths, and so on). The name exists for historical reasons, even though according to the usual mathematical definition such frequencies form an arithmetic series. An ideal string ( or air column ) can vibrate as a whole or in a number of equal parts, and the respective periods of vibration are proportional to the lengths. These increasingly shorter lengths or periods form a harmonic series (2:1, 3:1, 4:1, and so on). 1
