Understanding ukulele chords for beginners is essential. Every beginner ukulele player should start with C, Am, F, and G, four chords that use one or two fingers each and appear together in hundreds of songs.
Standard ukulele tuning is G-C-E-A, read from the top (thickest) string to the bottom (thinnest) string. The G string is usually re-entrant, meaning it's tuned an octave higher than you'd expect, which gives the ukulele its bright, chimey sound.
