Sometimes I hear Sonatas described as stuffy, serious music for snobby classical music audiences, as opposed to crowd-pleasing showpieces. Perhaps it's because of the whole "knowing when to clap" issue that arises during a multi-movement piece (I say, clap whenever you want to!), or because of the concentration it takes to appreciate a sonata in its entirety that I am warned not to program too many of them. But I really love the violin/piano Sonata repertoire, and I often program more than one when I give a recital. I love the filling out of a musical idea across three or four movements, as well as the partnership between the instruments. Plus, there are so many good ones to choose from!
In no particular order:
2. Beethoven's "Kreutzer"
7. Mozart Sonata No. 10 in B flat, K. 378
8. Beethoven "Spring"
9. Beethoven No. 7 in C minor
Neglected on my list are the wonderful Baroque sonatas of Bach, Handel, Corelli and Tartini. Also worth mentioning are several other French works including those by LeClaire, Faure, and Debussy. In short, what you are actually seeing here is music that I hope to program someday, if I haven't already!
