I do seem to be going through a lot of pieces on the violin these days. It might be worth getting pieces from the library to learn than to buy books, but unfortunately my local library is a bit small. Currently learning the Rondeau from Purcell’s Abdelazar which is really rather cool. (You’ll probably more familiar with it’s use as the theme to Britten’s Young Person’s Guide to the Orchestra.) Also trying to learn the Neapolitan Song from Tchaikovsky’s Swan Lake, which might be cool as well, but it’s rather difficult!
