Fundamental Frequency

Term Category: Acoustics

The Fundamental Frequency, or Fo, is more commonly referred to as pitch. The difference between the fundamental frequency and a pitch is that a pitch created by a singer, or most instruments, contains multiple frequencies including the fundamental frequency and overtones. The fundamental frequency is typically the lowest frequency that is being produced as seen in the image below the fundamental frequency was approximately 250Hz.

In singers, the frequency corresponds with the speed that the true vocal folds open and close. To sing A440 the true vocal folds open and close 440 times per second.
