Hello all. My friend and I have really enjoyed tackling the Crusell duo in D minor and I gather there are two more - in F and C. Does anyone know how these compare in technical challenge to the D minor one? I want to get my friend some clarinet music for Christmas and thought these might fit the bill. Also any other ideas of duets of moderate difficulty that we could try?

Still haven't got round to trying new instruments but will do so shortly. Someone suggested that I should perhaps try replacing the mouthpiece first to see if that makes a difference to the sound.
