Now that orchestra sessions just about over I'm going to buy some solo strings. I want to learn the Bach cello suite number 1, the Rabbath edition I think. I always thought it was played on solo strings but now I'm not sure. And I see a lot of people play it with a 5th string but I can't tell if they actually use it or not. I see a lot of threads about this but no one asks the easy questions. So my questions are simply, are there versions that use solo tuning? And, do I need a 5th string to play the first movement?
