Chord Transposer Calculator

Transpose notes and chords up or down by any number of semitones

Frequently Asked Questions

How many semitones is a whole step?

Two semitones make a whole step. One semitone is a half step, the smallest interval between adjacent keys on a piano.

Does it move the chord quality too?

No. Only the root note moves. Suffixes such as m, 7, maj7, or sus4 stay attached, so the chord type is preserved when you transpose.

Why can the same note show as a sharp or a flat?

A pitch like A sharp and B flat sound identical, so the output follows your accidental toggle to spell every note consistently with sharps or with flats.

What does transposing up 12 semitones do?

Twelve semitones is a full octave, so the note names come back to where they started, just one octave higher in pitch.
