If you plan on playing some orchestral and classical music on your ukulele, you have to be prepared to be particularly good at playing. It is possible because the ukulele also plays the same notes that can be played in all forms of music but expect that everything is going to be very complicated.
There are also some classic songs that will sound better in the ukulele as compared to other classical songs. You have to be familiar with all of these so that you can decide which songs you would like to try playing. One tip: look for classical songs that were originally written to be played for the guitar. These songs will probably sound great when played in the ukulele.
