The parts in these arrangements are designed for players from expert to advanced beginner; each song includes parts for two or three playing levels. The Conductor’s Score shows all of the parts, so players can see how the parts fit together. If there are more than three parts, the score's standard music notation make the note patterns easy to see.
The individual parts have a staff with standard notes and a staff with tablature that shows the rhythms.
Ukulele I often has more single notes than the other parts, and usually carries the melody and the most complex rhythms if there is syncopation. Ukulele I can expect to play higher on the fretboard than the other instruments, so, generally speaking, the player needs to feel comfortable above the 3rd fret.
Ukuleles II and III usually play single notes that accompany the melody; the notes and rhythms are easier than Ukulele I’s part.
Chords part. Sometimes there is a part with chords and strums only. Tablature and/or chord diagrams spell out the chord notes; using the belt and suspenders method, sometimes there is standard notation, also. Everyone in the ukulele ensemble needs to be able to change chords smoothly and in rhythm.
Baritone ukulele may play single notes, accompaniment chords or, sometimes, the melody. For some pieces there is a Bass part.
