Is this the concerto movement that Brahms never wrote? You can make your own mind up about that! The Brahms clarinet sonatas have long been a staple of the clarinet repertoire and I felt this movement would transfer well for a chamber orchestra. I made this arrangement with a pupil in mind. Although she could take on something more challenging, I had to bear in mind what the school orchestra could reasonably manage. To maintain the integrity of the original clarinet part, the strings have ended up playing in a slightly tricky key, however, the steady tempo should make it manageable. I would suggest cl, fl, 3x vln 1, 3x vln 2, 2x vla, vc, db would make a suitable balance, but there is no reason why a larger group should not tackle this piece as long as care is taken with balance.
