How to Transpose Music Between Keys
Transposing shifts all chords by the same number of semitones. There are 12 semitones in an octave. To transpose from C to G, shift up 7 semitones.
Common reasons: adapting for a singer's range, using a guitar capo, converting for transposing instruments like Bb trumpet.
Enter chords separated by spaces. The transposer handles sharps, flats, and preserves all suffixes (m, 7, maj7, dim, sus4).
Frequently Asked Questions
How to use a capo?
A capo on fret N raises pitch by N semitones. To play in G with capo on fret 2, use chord shapes from F.
Do chord qualities change?
No. Major stays major, minor stays minor. Only the root note changes. Am up 2 semitones = Bm.
How to transpose for Bb instruments?
Bb instruments sound 2 semitones lower. To write Bb parts from concert pitch, transpose up 2 semitones.
What is the circle of fifths?
Keys arranged by ascending fifths: C-G-D-A-E-B-F#-Db-Ab-Eb-Bb-F. Adjacent keys differ by one sharp or flat.
