Below is the first movement of Beethoven's first Violin Sonata, for Violin and Piano. For private use you may print the full score, or individual Violin and Piano parts. Beethoven wrote 10 such Violin Sonatas and this one is a good starting point. Although called Violin Sonatas with the violin playing the starring role, such sonatas by Beethoven and other composers are effectively duets with the piano acting as an equal partner. There are many recordings of the complete set, a recent such recording (on 4 CDs) features the dream team of Itzhak Perlman and Vladimir Ashkenazy. On Amazon.co.uk and Amazon.com you can hear the opening of this movement as it should be played.
Here is the corresponding Download MIDI file of the complete piece. If you don't always have a partner to play with, here are additional Midi files of the Piano alone and the Violin alone. These are handy to play along with as practice aids, but if you can it is much better to play along with another musician.
