Semitone Interval Calculator

Intervals between frequencies

Dave KobrenskiReference-Charts, Flute-Making-Tools Jun 17

An interval is the difference between two musical notes: the distance between two frequencies, often expressed in semitones (or cents). The below tool calculates the exact number of semitones between any two given frequencies, or, given a frequency and an interval, will calculate the note required to achieve that interval. Some facts: A semitone is equal to 100 cents. The twelve-tone equal temperament scale divides an octave into 12 semitones (of 100 cents each). A theoretical model of an equidistant heptatonic scale, where all the intervals of the seven-note scale were perfectly equal, would result in an interval of 1.714 semitones each.
