🎵 Semitone Calculator
Calculate the number of semitones between two notes or transpose a note up or down by a specific number of semitones. Useful for musicians, songwriters, singers, producers, and music students.

A semitone is the smallest commonly used interval in Western chromatic music. There are 12 semitones in an octave.
For equal temperament, the frequency ratio between two notes is:
2(semitones ÷ 12)

A Semitone Calculator helps musicians, singers, songwriters, producers, and music students determine the distance between notes in semitones, also known as half steps. It can also be used to transpose a note upward or downward by a specific number of semitones.
In Western chromatic music, a semitone is the distance between two adjacent notes on a piano keyboard, such as C to C♯ or E to F. There are 12 semitones in an octave.
Semitone calculations are particularly useful when transposing songs, changing keys, adjusting vocal melodies, analyzing intervals, programming MIDI, and working with samples. For example, moving a melody up 3 semitones changes every note by the same chromatic distance while preserving the melodic interval relationships.
The calculator also shows the corresponding chromatic interval and the equal-tempered frequency ratio between the notes.
Tip: When transposing a song, remember that every note needs to move by the same number of semitones. For example, transposing a song 2 semitones higher moves C to D, E to F♯, and G to A. This is useful for adjusting a song to better fit a singer's vocal range.
