Last year, you guys helped my out quite a bit for my debut in a community theatre pit orchestra for Secret Garden. This year, I'm playing in a chamber orchestra of 4 violins, 2 violas, 2 cellos, 1 bass (me) and for at least one piece 2 oboes, 2 french horns, flute and piano. One piece is actually written for bass and is short and simple. The other two are bass/cello parts and they're tough for me in spots. One is Vivaldi's Spring. The other is Mozart's Symphony No 29 in A major. Two basic questions. First, on the doubled bass/cello parts do some bassists simplify the higher/quicker parts to help keep them cleaner? Or is there another way of dealing with these parts besides laying out for a measure here and there? Second is a question of bows. I play French style and have two. One is an older (probably German) bow with black hair. The other is a newer Asian import with white hair. I've asked about these recently in the Bows forum here, because the black hair is much darker sounding. Which bow would be more appropriate for the chamber orchestra setting? I'm worried that the white hair bow would show intonation problems more obviously, but perhaps that can be managed by playing closer to the fingerboard on exposed parts? Thanks for any suggestions to help make my debut more successful...I have three weeks to learn the parts. We have only one rehearsal the night before the performance in a local church.
