Chords, key and tempo for any song, worked out on one machine. Ask and you will be let in, or not.

Drop in a song. It is analysed on this machine's GPU — tuning, beats, key and chords — and then you can scrub anywhere and read the chord at the top, with the fingering to play it.
Every song is analysed on one machine at home, and that machine is not answering right now. Nothing is lost — come back when it is on.
Drag the chord lane or the waveform to scrub. Click any chord to jump to it.
