Frequently Asked Questions
- How do I change the key of a song?
- Upload it, set the semitone shift, and Process. Semitones map directly to keys: +1 moves C to C♯, +2 moves C to D, -2 moves C to B♭. The tempo stays the same with Preserve Speed on.
- What key shift is best for singing?
- If a song sits just above your range, dropping it 1-3 semitones usually makes the high notes reachable without the track sounding altered. Combine with our vocal remover to build a custom-key karaoke track.
- Is transposing the same as pitch shifting?
- Technically yes — a key change is a pitch shift by a whole number of semitones with the tempo preserved. Musicians say 'transpose' or 'change key'; the underlying operation is identical.
