ChordBloom turns music theory into a garden. Chords bloom as petals around the key you're in โ€” tap to hear them, wander to neighboring keys, and watch harmony make sense visually. EXPLORE HARMONY BY TOUCH Diatonic chords, the circle of fifths, relative and parallel keys, tritone substitutions, modal interchange โ€” each view lays the theory out as petals you can play. Long-press to cycle extensions (7ths, 9ths, 13ths), choose close, open, or spread voicings, and phrase chords as blocks, strums, or arpeggios. REAL SYNTHESIS, ON DEVICE A full SuperCollider synth engine runs right on your phone alongside classic synth voices โ€” warm pads, plucks, bells, keys, and ambient textures. Every note is synthesized live, and it all works completely offline. AI IMPROVISATION Let the built-in improviser play melodies over your chord changes while you drive the harmony. SAVE YOUR PROGRESSIONS Collect chords into palettes and build progressions you can come back to. MIDI OUTPUT โ€” OPTIONAL UNLOCK Turn ChordBloom into a chord controller for your whole studio: a one-time in-app purchase unlocks BLE MIDI to hardware synths and CoreMIDI to DAWs and other iOS music apps. No account. No ads. No data collected.
