## About

> Sing your melody, find the key and work out the chords. Play it anywhere an idea finds you. Real chords, real voicings and real songwriting.
> 
> This was built to be a compact, portable instrument for musicians and songwriters of all levels.

Experts will appreciate the alternate chord voicing, offline use and the ability to work on songs anywhere.
> 
> Free to use. No email or account signup necessary.
> 
> How it works:
> 1. Tap to start, then sing or hum a melody.
> 2. Hold each note for a moment and Polychrome Computer will identify the key, then the eight chords of that key appear.
> 3. Work out the chord progression that fits your melody with the eight chord buttons and shift chord voicings as you go.
> 4. Or work without key detection and find the key and octave that suits you best.
