Key Transposer
Select a key and shift it by any number of semitones. See the transposed result in musical key, Camelot, and Open Key notation -all at a glance.
How Key Transposition Works
In Western music, there are 12 semitones in an octave. Transposing shifts every note by the same interval -so a track in A minor transposed up 3 semitones becomes C minor. The mode (major/minor) stays the same; only the root note changes.
On the Camelot wheel, this relationship is less intuitive because Camelot is arranged by fifths, not chromatic steps. One semitone up doesn't move you to the next Camelot number -it jumps 7 positions. This tool handles the conversion so you don't have to count manually.
Common Use Cases
- Pitch shifting without key lock: When you change the speed on vinyl or a CDJ with Master Tempo off, the key shifts. Use this tool to find the new key after a pitch adjustment.
- Mashup preparation: If an acapella is in a different key than your instrumental, transpose one to find a compatible key match.
- Creative mixing: Deliberately transpose a track to create a harmonic bridge between two songs that wouldn't normally mix well.
- Production: When sampling or remixing, find the key of a pitched-up or pitched-down sample.
Semitones and Pitch Fader
Without key lock, approximately every 6% change in pitch fader position shifts the key by one semitone. So +6% ≈ +1 semitone, +12% ≈ +2 semitones, and so on. Use our pitch & tempo calculator to find the exact BPM change, then use this tool to see the resulting key shift.
