From a hum to a harmony
No music theory needed. If you can hum it, Alchemy can work out what goes with it.
Sing, hum or play
Tap record and perform your idea. Your pitch draws live as you go, from your voice or any instrument.
See the key
Alchemy picks out every note and finds the key, including Dorian and Mixolydian modes.
Choose your chords
Get a progression that fits your melody. Tap any chord to hear what else would work.
Made for songwriters
Everything you need to catch an idea before it slips away, then grow it into a song.




What's inside
Careful listening and real harmony, in an app that stays out of your way.
Accurate note detection
Follows your notes through vibrato, slides and drifting pitch, and hears quiet singing too.
Your chord style
Simple triads, extended chords with 7ths, sus and add9, or chromatic colour with borrowed chords.
Your pace
Change chords every two bars, every bar, every half bar or on every beat.
Layers and count-in
Record harmonies, instruments or beats over your take, with a count-in and loop recording.
Lock to the beat
Tighten the timing of your melody, and gently tune your voice if you like.
MIDI export
Send melody, chords and bass to GarageBand, Logic or any DAW. Or share a chord chart as text.
