So I only have a few measures of a first movement but I hope to expand this into a full 4 movement string quartet. Thing is, I find it hard to get the combination of being in sonata form and still being interesting when it gets past duets into trios and quartets. I know it should be easier because I have more freedom with a string quartet than with a piano sonata but no, I have always found piano sonatas easier to compose.Here is my first draft. You can see that I go from a Tutti to the cello playing solo which really brings out the warm sound of the cello. I plan on having the other instruments come back one by one until I reach Tutti again. So here is the link:https://musescore.com/user/50070/scores/5453458

Transcription to C-instrumentsI own the partiture of 'Sax in the City of Alain Crepin' inclusive all parts and the altsaxophone solo for saxophone-orchester (Es and Bes instruments). I want to play the altsaxophone-solo with my accordeon-ensemble (all C-instruments). How can I transcript all the music to C-instruments (exclusive the Alt-saxophone solo)? Can someone help me?
