Chordzilla — Create chord progressions and melodies, all in one compact app

Build a chord progression, layer a melody on top, then hand it off to AI. Chordzilla lets you complete that entire creative flow from a single smartphone. We'll keep improving and adding features with future updates.

Chord Progression Editor

Just pick a key and scale, and Chordzilla suggests chords that fit naturally next. Diatonic chords, substitute chords, borrowed chords, tritone substitutions, subdominant minor, and more — you can build rich harmonies without knowing any music theory. Save your chord progressions as sections and build your own personal chord library.

Melody Editing in the Piano Roll

Tap to draw melodies right on top of your chord progression. Piano keyboard input is also available (premium feature). Auto-generate a sample melody that fits your chord progression — perfect for sparking inspiration when you're stuck.

Genre Presets

When starting from scratch feels overwhelming, kick things off with a template. Includes 18+ presets across a variety of genres. More improvements coming in future updates.

AI Integration

Automatically generate prompts to feed your chord progressions into music generation and lyric-writing AIs. Key, scale, BPM, section structure, and chord progression are all bundled into a single AI-ready block of text. Pair it with your exported WAV file, copy, paste — and get AI compositions that sound exactly the way you envisioned.

MIDI Export

Export your chord progressions and melodies as MIDI files. Import them into a DAW to take your arrangement to the next level.
