Identifying the A-family Chords on Your Ukulele
In playing chords in the A family on your ukulele, you use the everyday A, Bm, D, and E7 chords. And, in addition to those chords, you use the slightly trickier C♯m and F♯m chords:
C♯m uses the Am moveable shape (familiar from Bm) moved up so that you’re barring across the fourth fret. The four at the top-right corner in the chord diagram indicates that, rather than starting at the nut, the diagram starts at the fourth fret.
F♯m is just the A chord with the E-string played at the second fret with your ring finger.Diagrams of the A chord family.
The A family of chords works particularly well for blues songs.
