What notes are in the Caug chord?
The Caug chord is built from three notes: C, E and Ab (the root, major 3rd and augmented 5th). On the ukulele the C is doubled, so you get a nice full sound. That raised fifth gives an augmented chord an eerie, unsettled shimmer, like the music is about to lift somewhere unexpected.

When that feels good, work on switching between chords faster. When you are ready, try some easy ukulele songs.
