Tutti is a free tool that analyzes a YouTube link or audio/video file to detect the key, tempo (BPM), time signature and chord progression, then builds guitar chord charts and TAB. Results are shown with a playback cursor so you can play along.
A chord progression lists the chords in the order they change. At each chord name (e.g. G, Em, C), fret that chord and strum in time.
