Hear the strings in order
A common soprano, concert, or tenor ukulele setup uses G, C, E, and A from the fourth string to the first. With high G, the fourth string sounds above the C and E strings rather than below them. This is called reentrant tuning. Pluck each open string slowly and sing the contour. The pitches do not rise in one continuous staircase across the instrument. That matters when you choose a bass note or assume the first string touched by a downstroke must supply the lowest sound.
Check the tuning your instrument actually uses
Some ukuleles use low G, and baritone ukuleles commonly use a different tuning altogether. Confirm your own setup with a tuner and the instrument's string specifications before following a diagram. A shape intended for one tuning may produce a different chord in another. Do not tighten an unfamiliar string toward a guessed pitch without checking what it was designed for. Once the tuning is known, play a familiar chord and identify its lowest audible note rather than relying only on the physical order of the strings.
Arrange with the available register
On a high-G instrument, use the lively upper register to support rhythm and chord color. A picking pattern can move between strings in a way that creates a close, ringing texture rather than a conventional low bass followed by high notes. When using AudioChords ukulele diagrams, verify that the shapes suit your tuning and listen to how they support the melody. If the recording contains a deep bass line, preserve its harmonic direction through chord choices or collaborate with a lower instrument. Your ukulele version can remain convincing without pretending to occupy the same register as the original production.
