About this calculator

Use this calculator to transpose a pitch in hertz by a whole number of equal-tempered semitones. Enter the starting frequency and how many semitones to move (negative goes down).

out = Hz × 2^(n/12). 440 Hz up 7 semitones is about 659.2551 Hz (E5). MIDI note numbers belong on a note-frequency tool, not here.

Hz: Starting frequency.

Semitones: Interval; negative is down.

Hz: Shifted frequency.
