I have Boismortier 6 concerti for alto recorder, all duets. I've learned much of this, although it will keep me busy for a while learning both parts of each piece. I play a Sammartini (sp.) sonata that's also a duet--and that's it for duets. Any suggestions for something in my intermediate range? As long as there's one alto in the mix, I suppose trios or other small ensemble pieces would be welcome too. But it's hard enough finding just one other recorder player (the players I know are all much more advanced than me and I don't want to make them suffer.)
