Playing the ukulele is very similar to playing a guitar. The strumming and picking of the right hand translates easily between the two, as well as the fretting and chording that the left hand does. In fact, the way the notes are separated from string to string on the ukulele are the same intervals as the notes from string to string on a guitar. You can think about it like this: If you capo a guitar on the 5th fret and play the top 4 strings, those are the same notes as a ukulele! You can do all the same chord shapes and scale patterns that work on a guitar on your uke.
