11/10: OH MY GOD. Got some "real life" experience with the concert I did last night. Due to a tragic loss of a family member for our English horn player, I got a second oboe part for Mahler's Totenfeier at 2pm yesterday, had half an hour to look at it before the dress rehearsal, and then played it on the concert at 8pm. It was a HIGH STRESS SITUATION. Good news was that I got a helluva lot more right notes in the concert than I did in the dress rehearsal.
Apparently the fear was all over my face, visible from the audience, lol. I must say though, the guy who originally had the part who was then switched to English horn... SOOO MANY KUDOS. Much harder parts, much more exposed solo passages, and he *nailed* it.
We were both sweating A LOT.
