🎸 Chord & Note Transposer

Enter notes or chords and shift them up or down by semitones — with a capo hint for guitarists.

Transposed

D A Bm G

Guitar: to sound 2 semitone(s) higher, use a capo on fret 2 and play the original shapes.

Shifts every note or chord root by the same number of semitones (12 = one octave). Chord qualities (m, 7, maj7, sus4) are preserved. A capo on fret N raises pitch N semitones, so the same shapes sound N semitones higher. 🔒 In your browser.

How the chord & note transposer works

The tool moves each note or chord root by the number of semitones you choose, wrapping around the 12-note chromatic scale (12 semitones is a full octave). Chord qualities like m, 7 and maj7 are preserved. You can spell the result with sharps or flats, and it shows the equivalent guitar capo position.

Transposing changes the key without changing the tune — handy for matching a singer's range or an easier set of chord shapes. On guitar, a capo on fret N raises everything N semitones, so you can keep familiar open-chord shapes while playing in a higher key.

Frequently asked questions

How do I transpose a song to a different key?

Shift every chord and note by the same number of semitones. To go from C to D, move up 2 semitones: C→D, G→A, Am→Bm, F→G. Enter your chords and set the semitones and the tool rewrites them.

How does a capo change the key?

A capo on fret N raises the pitch by N semitones, so the same shapes sound higher. To play in a key that's N semitones up while using easy open chords, capo on fret N and play the original shapes.

How many semitones between keys?

Count up the chromatic scale: C to D is 2 semitones, C to E is 4, C to G is 7. An octave is 12. The transposer handles the counting and wrapping for you.

Does transposing keep the chord type?

Yes — only the root moves. A minor chord stays minor, a 7th stays a 7th. So Am transposed up 2 semitones becomes Bm, and G7 becomes A7.

Should I use sharps or flats?

It depends on the target key's key signature, but for a quick transpose either spelling is fine. Toggle flats if the result reads more naturally that way (e.g. B♭ rather than A♯).
