### noun

physics music a component of a periodic quantity, such as a musical tone, with a frequency that is an integral multiple of the fundamental frequency. The first harmonic is the fundamental, the second harmonic (twice the fundamental frequency) is the first overtone, the third harmonic (three times the fundamental frequency) is the second overtone, etc
music (not in technical use) overtone: in this case, the first overtone is the first harmonic, etc

### Noun

Periodic motion whose frequency is a whole-number multiple of some fundamental frequency. The motion of objects or substances that vibrate or oscillate in a regular fashion, such as the strings of musical instruments, can be analyzed as a combination of a fundamental frequency and higher harmonics.♦ Harmonics above the first harmonic (the fundamental frequency) in sound waves are called overtones. The first overtone is the second harmonic, the second overtone is the third harmonic, and so on.
