Change a song’s key without changing its tempo.
Shift a song up or down by up to 24 semitones — the tempo stays exactly the same. Tap the ♭ and ♯ buttons to move a semitone at a time, or use the slider to fine-tune in cents. Great for singing in a comfortable key or matching a differently tuned instrument.
Back to the original key: when the pitch is shifted, its value above the slider is marked with ↺ — tap it to return to the original key. You feel a light tap whenever the pitch reaches the original key.
Pitch practice
In a practice you can step the pitch up or down automatically with each loop — a great way to master a part in every key. As the pitch changes, the chords shown follow along, so you always see the chords for the key you’re hearing.
Change the speed while you practice: use the − and + buttons above the play button to go 5% slower or faster — double-tap the value to return to 100%. The new speed starts with the next loop, so the tempo never jumps in the middle of a phrase.
💡 Tip: Learn a tricky part in an easier key first, then move it back one semitone at a time until you’re at the original.
