The key of G major on mandolin
G A B C D E F♯ — and everything inside it.
The key of G major on mandolin: the scale, the chord on every degree, the seventh chords and the pentatonics — drawn above, each a tap away. The row of chips over the mandolin is the key’s chords; the dropdown switches it to seventh chords or pentatonics, the shape menu draws a chord as one grip at a time, and a tap on any note finds the chords that hold it. For the why, read chords in a key.
