The lowest allowed frequency, n , is called the fundamental frequency of vibration. Integral multiples of the fundamental frequency are called the harmonics, the fundamental frequency being the fundamental or 2n , the third harmonic is 3n , and so on. The higher allowed frequencies are called the overtones.
