    F#9 chord on cavaquinho, shape 4: from fret 6, notes F#, A#, E, G#

The F#9 has 5 notes, and on cavaquinho only 4 fit at a time. The shapes on this page leave out: 5th (C♯). 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 (F sharp).
