As most of you guys know, I am about as new to the whole arco orchestra thing as they come, so I have been woodsheding bigtime this year, as it is my first effort at classical string bass performing. In all modesty, I am pretty amazed at the overall sound I have been getting, but there are a few places where it still sounds like a cat in a trash can. One of the pieces we are performing is Vivaldi's Gloria. Overall, it isn't the toughest thing in the world, but there is a passage that makes a octave jumps on the eights. C-c-C-C-C-c-C-C-C, then on the G. It's marked at 120 but I think the conductor is taking it about 130 or better. The nice thing is there are rests before and after this passage so I can set up the bow however will best get me through this. Any tips on how to approach this? I am really struggling to stay on the pulse of the music. Many thanks in advance.
