This document discusses using pentatonic scales on the ukulele. It notes that the ukulele has just four strings, making it easy to learn. It explains that pentatonic scales use five tones and sound good, even when played randomly. Common songs that use pentatonic scales are listed. The open strings on the ukulele form a pentatonic scale, so accidentally hitting them usually sounds fine. Finger patterns for the C major and minor pentatonic scales are shown. The document emphasizes learning the finger patterns rather than note names and provides examples of "little dipper" and "big dipper" finger patterns that can be moved to different keys.
