We're currently trying to play the first movement of Beethoven's duet No. 1 (originally written for clarinet and bassoon, but we're adapting an adaptation for violin and viola). Here's the score I've prepared - all the notes are there now (I hope), but dynamics aren't quite complete yet (requires Flash -but I can email PDF file on request):
If you click play above, you'll get a computer-sound version - but here is how it should sound like when it's played by proper musicians.
PS: an amazing and growing list of repertoire for cello and flute is here.
PPS: We played this at the Oxford Music Festival in January 2013. The adjudicator used words like "brave" and "challenging" a lot, but we made it to the end, so I count that as a success. We're now moving on to the third movement of the same piece, which appears to be a little bit easier (hoping I can get my head round the triplets). After writing up around 40 bars, I realised that a version of Movt. 2 and 3 playable with our instruments is actually published in the book:
Duets for Violin and Violoncello for Beginners, Vol 2
(Arpad Pejtsik & Lajos Vigh, eds.)
Editio Musica Budapest Z. 14062
so we'll work with that at the moment, maybe finish the draft on noteflight later.
