Play the melody or chords on the piano below — or on your computer keyboard (A–;) or a MIDI keyboard. Notes you repeat count more, so play the song through once.
Type chords with spaces between them. Slash chords (C/E), 7ths, sus and dim all work.
Play or sing the song for 20 seconds or more.
Play the song out loud near your device, or sing the melody. Give it 20 seconds or more for a steady answer. Works best with headphones off and the volume up.

Tap Start, then slide your voice slowly from your lowest comfortable note up to your highest, like a siren. Tonic keeps the lowest and highest notes you hold steady for a moment. Stay comfortable — don't strain.
Voice types are a rough guide. Where your voice feels easy and sounds best matters more than the lowest and highest notes.
