While sitting First Chair is a great accomplishment, it is not the only goal or the end goal. I'm a lot more interested in a student's personal development along the way, and his/her ability to play beautifully. Flute playing should be enjoyable and low-stress most of the time! Private lessons teach students how to accomplish more in less time, which places them ahead of their peers, but they also receive training in overcoming performance anxiety, technique, and tone studies, all of which help them perform better, more consistently.
Congratulations, Marissa, and may you enjoy a lifetime of music making!
