Your voice
Define your comfortable vocal range. We'll use it to find the best key for any progression.
↓ C3↑ G4
We'll capture your range in two steps: lowest note, then highest.
Detect a song's key
Hum a melody for ~10 seconds and we'll guess the key. The Copilot can take it from there — listen to candidate progressions and pick the one that matches.
Capture a sung melody
Sing a short phrase and capture the note order, rhythm, rests, and likely key. This creates a draft melody for Copilot to harmonize or continue.
