Chords in every key
The seven chords of every major and minor key, for mandolin. In a major key the chords run major, minor, minor, major, major, minor, diminished (I ii iii IV V vi vii°); in a minor key minor, diminished, major, minor, minor, major, major (i ii° III iv v VI VII). Pick a key to hear its chords, see their shapes and play progressions in it.
How to use the table
Find the key of a song in the first column: its row holds the chords the song is most likely to use, and the numerals at the top say what each does. The same progression in another key is the same numerals in another row, which is how to move a song to a key that suits your voice. Each major key shares its chords with the minor key three half steps below it, its relative minor: C major and A minor, G major and E minor.
Each chord opens with every way to play it on mandolin. Also: every mandolin chord, the mandolin tuner, and every key on guitar, bass, ukulele and banjo.
