How do you get into the LSO?

Answer 1

I will assume you mean the London Symphony Orchestra. Call their main office, and inquire as to when they will have their next open audition (if they even have open auditions). They can give you any pertinent information. If you do get to audition for membership in the orchestra (and even getting to audition would be a terrific achievement) they will have a list of pieces, or perhaps certain orchestra passages, that they will want to hear you play - you'll usually know what those are beforehand. They will also have you do some sight-reading You won't know what those are beforehand. Good luck.
