How to play F♯9 on ukulele

Shape 1, 1-4-2-1, reading from the G string on the left:

Put your index finger on the G string at the 1st fret, which is G♯.
Put your middle finger on the A string at the 1st fret, which is A♯.
Put your ring finger on the E string at the 2nd fret, which is F♯.
Put your pinky finger on the C string at the 4th fret, which is E.

The pinky takes a note here. Keep it curved and close to the fretboard between chords so it has less distance to travel.
The shape stretches across four frets. Bring your thumb lower behind the neck to open the hand up.
On ukulele you strum all four strings. The top G string is tuned higher than the C, which is why ukulele chords sound bright and close.

Other ways to play F♯9

9-8-6-9: movable shape at the 6th fret, medium. Use it when the next chord sits nearby on the neck.
11-10-12-11: movable shape at the 10th fret, medium. A high voicing for when the low version is taken by another instrument.

Playing F♯9 with a capo

A capo turns an open chord into F♯9: capo on the 6th fret and play the open C9 shape (0-2-0-1). Handy when the rest of the song's chords also have open shapes in that position.

Changing from F♯9 to the chords around it

The chords F♯9 usually goes to, and what changes under your fingers.

B (dominant, pulls to the chord a fifth below): F♯9 (1-4-2-1) to B (4-3-2-2): move the index finger to the E string, 2nd fret, the middle finger goes to the A string, 2nd fret, your ring finger lands on the C string, 3rd fret. No finger can stay, so practice lifting all of them together and landing the new shape as a unit. The two chords share F♯, which is why the change sounds smooth. B on ukulele
Bmaj7 (I in B major): F♯9 (1-4-2-1) to Bmaj7 (3-3-2-2): move the index finger to the E string, 2nd fret, move the middle finger to the A string, 2nd fret, the ring finger goes to the G string, 3rd fret. Nothing carries over, so drill it slowly, lifting and landing all fingers at once. Shared notes: F♯ and A♯. Bmaj7 on ukulele
G♯m7 (vi in B major): F♯9 (1-4-2-1) to G♯m7 (1-3-2-2): your index finger stays put, move the middle finger to the E string, 2nd fret, the ring finger slides across to the A string at the same fret, your pinky finger lands on the C string, 3rd fret. F♯ and G♯ carry over from one chord to the other. G♯m7 on ukulele

F♯9 is a dominant ninth: F♯7 with the ninth on top. With four strings, shape 1 leaves out the perfect fifth (C♯); the ear fills it in, and the chord still reads as F♯9. The usual guitar shape, 2-4-2-3-2-4, has room for all of them. Play it once strummed and once picked to hear the difference.

Practice F♯9 in two minutes

Before strumming, play 1-4-2-1 note by note: G♯ then E then F♯ then A♯. A dead note tells you exactly which finger to fix. Finish by moving between 1-4-2-1 and 9-8-6-9 to learn two positions of the same chord.

G♭9 is another spelling of F♯9. Same shape, same sound.
