FAQ
Good questions.
How accurate is the chord detection?
It gets the progression of most pop, rock and folk songs right. Dense jazz harmony and fast changes can come out simplified, so treat it as a strong first draft and check by ear.
Does it show chords for piano?
Chords are shown by name, with guitar diagrams. The names work for any instrument.
Can I transpose the chords?
You can change the song's key, and play along in the new key.
