Strumming treats all four strings as one unit. Fingerpicking separates them - each finger plays one string, so you can build melody and rhythm at the same time. The key is consistency: the same finger always plays the same string.
The standard assignment is p-i-m-a. Each letter stands for the Spanish name of the finger: pulgar (thumb), índice (index), medio (middle), anular (ring). Here's how they map to the ukulele strings in standard GCEA tuning:
p (thumb) - G string (4th, lowest pitch)
i (index) - C string (3rd)
m (middle) - E string (2nd)
a (ring finger) - A string (1st, highest pitch)
Your First Pattern
Hold a C chord and pick each string in order from low to high: G (thumb), C (index), E (middle), A (ring finger). That's it. One cycle, four notes, four fingers. Do it again. Keep going.
The goal for now is not speed. It's consistency - making sure the same finger goes to the same string every time, and that each note sounds clear and even in volume. Speed comes from repetition, not from trying to move fast.
Nail, Flesh, or Both?
Most beginners use the flesh of the fingertip. That's fine. Players who want a brighter tone grow the nail on their picking fingers and strike with the nail edge. Either works - pick one and stay consistent for now.
Adding Am
Once you can do four clean repetitions on C without looking at your right hand, switch to Am. Same pattern: G-C-E-A in order, one string per finger.
The chord change is a left-hand problem. Keep your right hand moving in the same rhythm even during the chord change - the pattern doesn't pause.
Practice
Alternate between C and Am, four picks per chord. Hold each chord for the full four picks before switching. Start slow enough that you can hear each note clearly. Build to a tempo where the pattern feels automatic - then you're ready for more complex patterns.
Questions and Answers
What is PIMA in ukulele fingerpicking?
PIMA (pulgar, índice, medio, anular) is a standard notation for assigning fingers to strings. On ukulele in standard GCEA tuning, the thumb (p) plays the G string, index (i) plays C, middle (m) plays E, and ring finger (a) plays the A string. Consistent finger-to-string assignment is what makes fingerpicking patterns reliable.
How do I keep fingerpicking notes even in volume?
The thumb and ring finger naturally produce more volume than the index and middle fingers. Practice deliberately softening the thumb and ring finger strokes while strengthening the index and middle. Slow, focused repetition evens out the differences over time.
