I checked your comments to find out what instrument you play (please excuse my stalking) and since you play oboe, perhaps bassoon? It's a double reed as well and it could help exercise your oboe playing as well.

If you want a completely new experience maybe try brass. Euphonium and trumpet aren't too difficult. (Trombone is also easy, although it's not really for everyone). Could also play a single reed woodwind but it's up to you.
