Chordzilla — A Compact App for Creating Chord Progressions and Melodies

Chordzilla is a compact songwriting app that lets you create chord progressions and melodies directly on your smartphone.

Build chord progressions, compose melodies with Piano Roll editing, and export your work as WAV or MIDI. Capture musical ideas quickly with a simple and intuitive workflow.

Chord Progression Editor

Simply choose a key and scale to receive suggestions for the next chord.

Explore diatonic chords, substitute chords, borrowed chords, tritone substitutions, subdominant minor chords, and more. Even without extensive music theory knowledge, you can build natural-sounding chord progressions with ease.

Save your progressions as sections to build your own reusable chord library.

Piano Roll Melody Editor

Create melodies by tapping directly on the Piano Roll.

Premium users can also enter notes using the on-screen piano keyboard.

Melody examples matched to your chord progression are available to help inspire new musical ideas.

Includes over 18 presets, with more planned in future updates.

The generated text can be copied and used with compatible music production tools and external services.
