Chords in the key of A minor on ukulele
The key of A minor has seven diatonic chords: Am, B°, C, DmDmDmDm, EmEmEmEm, F and G. As sevenths: Am7Am7Am7Am7, Bm7b5, Cmaj7Cmaj7Cmaj7Cmaj7, Dm7Dm7Dm7Dm7, Em7Em7Em7Em7, Fmaj7Fmaj7Fmaj7Fmaj7 and G7G7G7G7. They come from the A natural minor scale, A, B, C, D, E, F and G, one on each note. On ukulele, the shapes below are the seventh chords of every degree, and the tonic one has C in the bass.
On the ukulele, the high reentrant G makes every shape light — and with four strings, every note is exposed. Its soft nylon strings sound warm and mellow, light enough to float gently over a song.
