Chords and harmony, made easy!
As a ukulele and bass player, I've always found it easier to learn theory and explore ideas on a piano. But I never had the skills to play it fluently... That's when the nerd in me stepped up and said, "Why not build an app to simplify this?" And so, Chordi was born—a powerful idea box app for musicians like you! 😎

🎨 Creative Modes
Take your creativity even further with these powerful modes:
- Free Mode – Play freely—just tap notes or build chords without any restrictions.
- Key Mode – Select a scale and key, and let Chordi guide you through fitting chords. From triads and sevenths to secondary dominants and modal interchange, you'll always have the right options at your fingertips. Chordi even suggests what to play next based on chord progression rules.
- Replay Mode – A creative alternative to traditional loopers—perfect for those who find the red record button intimidating. Any notes played in Free Mode or Key Mode are automatically stored. Enter Replay Mode to revisit your ideas, delete individual events, add a gap at the end for a smooth loop, or export your session as a MIDI file. Capture inspiration without pressure and refine your ideas with ease. Beware, leaving that mode starts recording again.
🎵 Rhythm Modes
Explore chord rhythms and experiment with musical textures in these modes:
- Normal Mode – Play single notes or full chords with available modifiers.
- Arpeggiator Mode – Transform chords into arpeggios. (Experimental)
- Strummer Mode – Strum your chords like a guitar or harp. (Experimental)
