After playing the bass clarinet for going on 3 months now, I've found that I'm still having difficulty playing high F - C (haven't even tried going any higher). I've finally managed to get the D and E at the top of the staff under control But F and up is very difficult to play, with the high B and C almost impossible to sound. Maybe I'm just being much too impacient? I'm also having difficult playing staccato notes throughout the low end of the bass clarinet. I'm playing on a Vandoren B-45 and a B-40 (testing them both out right now, not sure which one I favor) with vandoren 2.5 or 3 traditional reeds. Any tips/comments/suggestions would be appreciated!
