Name riffs and chords, and tune up, straight from your mic.
Every fret is one semitone. Count up from the root to find each note. Shaded boxes are the major scale, which is where the numbers 3, 5 and 7 come from.
Each button changes the chord by one note and plays before and after, so you can hear what that note does.
Tap a string to hear its note and lock the tuner to it. Tap it again to go back to auto.
