I got to play my concerto for the first time with the orchestra on Tuesday. To be honest, I was brimming with excitement and a bit of nerves, and was wondering how it was all going to sound, so I didn't play my best. We rehearsed it at the end of rehearsal, too, and I didn't do a good warm-up routine that day, so it all culminated into fatigue, which resulted in some things not going so well. But enough did go well for me to not be too upset. Today I rehearse again, and I'll have much fresher and better chops to tackle it. I'm ready for it, and plan to record the rehearsal with my Zoom H4n. Granted it all goes well, plan on me posting the recording on this site.
Take care and value music.
