How to play Baug on ukulele

Shape 1, 0-3-3-2, reading from the G string on the left:

B: index finger, 2nd fret of the A string.
D♯: middle finger, 3rd fret of the C string.
F𝄪: ring finger, 3rd fret of the E string.
Leave the G string open: F𝄪.

If an open string sounds dead, a fingertip is leaning on it. Come down more on the tips, with your knuckles bent.
Strum with the pad of your index finger or thumb, all four strings, across the spot where the neck meets the body.

8-7-7-6: movable shape at the 6th fret, medium. Same notes, stacked differently, so it sounds a little different.
12-11-11-10: movable shape at the 10th fret, medium. Up the neck the chord gets thinner and brighter, a good contrast to the open version.

Changing from Baug to the chords around it

Songs rarely hold Baug for long. Here's what your hand does on the moves that come up most.

E (the raised fifth pushes up into the IV): Baug (0-3-3-2) to E (1-4-0-2): move the index finger to the G string, 1st fret, move the middle finger to the A string, 2nd fret, the ring finger goes to the C string, 4th fret. Nothing carries over, so drill it slowly, lifting and landing all fingers at once. Shared note: B. E on ukulele
F♯ (V in B major): Baug (0-3-3-2) to F♯ (3-1-2-1): your index finger lands on the C string, 1st fret, your middle finger lands on the A string, 1st fret, move the ring finger to the E string, 2nd fret, the pinky finger comes down on the G string, 3rd fret. No finger can stay, so practice lifting all of them together and landing the new shape as a unit. F♯ on ukulele
G♯m (vi in B major): Baug (0-3-3-2) to G♯m (4-3-4-2): your index and middle fingers stay put, your ring finger lands on the G string, 4th fret, the pinky finger comes down on the E string, 4th fret. B and D♯ carry over from one chord to the other. G♯m on ukulele

Baug is an augmented triad: two major thirds stacked, with a raised fifth. All 3 notes of Baug fit on the ukulele's four strings, with one of them doubled. On ukulele you hear it best picked slowly, string by string.

Getting Baug under your fingers

Pick shape 1 one string at a time, low to high: F𝄪, D♯, F𝄪, B. Every note should ring clearly; if one thuds, adjust that finger before you strum. Then switch to 8-7-7-6 and back four times without looking at your hand.
