A roll is a chord dealt out one string at a time: hold a grip you already know, assign one finger per string, and let the fingers take turns. On a reentrant ukulele the result is disproportionately pretty — the four strings live so close together in pitch that a rolled chord shimmers like a small harp rather than climbing like a guitar arpeggio. If you can hold C, you can start this page today.
The hand
Classical finger names, which every fingerstyle resource uses: p is the thumb, i the index, m the middle, a the ring. On GCEA the standard assignment is one finger per string: p takes the fourth (G) string, i the third (C), m the second (E), a the first (A). The thumb strokes down, the fingers pull up toward the palm; fingertips stay close to the strings, and the hand itself does not bounce. Yes, the thumb plays the uke’s high reentrant G — that inversion is precisely why rolled ukulele chords sparkle instead of plod, and why this technique leads so naturally into campanella playing.
The drills
One column per note, all on the open C grip. The forward roll (p–i–m–a) is the fundamental: four even notes, each string ringing into the next, no finger louder than its neighbors — evenness is the entire game, and the ring finger will be the weak one; feature it rather than hiding it. The backward roll (a–m–i–p) reverses the deal and is noticeably harder to keep even. The pinch-and-roll — thumb and ring striking the outer strings together, index and middle filling the inside — marks the beat like a heartbeat and is the pattern behind half of recorded fingerstyle uke.
Using it in songs
Any song you can strum, you can roll: keep the left hand’s changes exactly as they are and replace each bar’s strums with one forward roll per beat — the changes themselves come from the chord reference, and every progression in the progression reference works rolled. Verses rolled, choruses strummed is the oldest arrangement trick in the book, and it needs nothing but this page and strumming patterns. When the fingers are even at a walking tempo, graduate: the campanella scale maps ask these same four fingers to carry an actual melody, and rolls are how they train for it.
