How to Calculate Overtones
Vibrating air causes all sound. The vibrations can be measured in frequencies, usually in Hertz (Hz). One Hertz is one vibration per second. The main vibration is called the fundamental tone, but we also hear overtones, which are fractions of the fundamental sound. For example, middle C on a piano has a frequency of 262 Hz.
