Here is a fun one. When I was in Highschool, I think 🙂 (It’s been a while) we had a concert with the orchestra, playing Bolero (Ravel). When we got on the stage and getting ready to play we noticed that our part was missing. We panic a bit for a few momnts. Obviously there was nothing we could do at that point. Lucky it was this piece to play, otherwise would have been quite embarassing trying to fake playing the whole piece.. So we literally tried to look at the desk in front of us and to figure out when the chords were changing (lucky most of it was pizzicatto :))) ) and of course listening everything around us, so we don’t do mistakes to look stupid. I guess that was one good lesson and a big stept towards becoming a professional. I will never forget that day.
