I've found recently that our conductor's demands for more and more volume from the basses is almost completely destroying my tone as I play. I used to have a nice warm and fairly broad sound, albeit i had difficulty generating higher dynamics, and I could fine-tune notes with my lip rather well - something which was instilled in me very early on as it's so important on a big instrument. Now It seems I'm so focussed on trying to generate the volume asked for, my tone's become hard, thin and flat-sounding, I find it hard to lip the note in to those around me as blowing too hard compromises my (and their) tuning so I never know if I'm flat or sharp. Add to that my note production's gone to pot and I'm not having much fun playing at the moment. I can't seem to find a compromise that keeps me happy on quality, or him happy on volume. I know if I was sat in B&R or Grimey's bass section they'd barely notice I was there, compared with the noise that standard of player can generate, but I'm not expecting to reach that standard overnight (if ever!) How do I work on improving my volume without completely ruining my sound? It's really starting to annoy me not being able to find a good balance of the two.
