Chord Progression Manager

Build and play chord progressions in seconds. Explore new musical ideas with an AI music assistant and a built-in synthesizer. Your creative songwriting companion.

Chord Progression Manager is the fastest way to build, play, and save chord progressions on iPhone, putting a live, playable chord lane right in your pocket.

— BUILD YOUR PROGRESSION — Pick a root note, chord type, and tension, then add it to your progression with a single tap. Reorder or delete chords freely. Use the voicing editor to fine-tune individual notes on an interactive piano roll and craft exactly the sound you want.

— PLAY IT BACK — Hear your progression immediately with the built-in synthesizer. Adjust tempo and transpose the entire progression up or down by semitone — no need to rebuild from scratch when you change keys.

— SAVE & ORGANIZE — Save as many progressions as you like and keep your favorites just a tap away. Reopen any saved progression into the editor and keep building.

— AI MUSIC ASSISTANT — Stuck on what chord comes next? Ask the built-in AI chat. Get suggestions for chord substitutions, borrowed chords, reharmonization ideas, and more — powered by any OpenAI-compatible endpoint you configure.

Chord Progression Manager is free to download and use. AI chat features require your own LLM API key.
