    Bb7M(9) chord on cavaquinho, shape 2: from fret 7, notes Bb, D, A, C

The Bb7M(9) has 5 notes, and on cavaquinho only 4 fit at a time. The shapes on this page leave out: 5th (F). That is standard practice: the 5th goes first (it barely changes the sound) and, if a string is still missing, the root, which the bass player usually covers.

Numbers are fingers: 1 index, 2 middle, 3 ring, 4 pinky. x = do not play the string, o = open string. The coloured dot is the root (B flat).
