Anyway, I worked with the first violin section for a concert on October 26. The repertoire was pretty ambitious (which is great for this age group); Mendelssohn's Hebrides Overture and Beethoven Symphony 5. But the students were very excited to play those masterworks and it was so rewarding to work with this group. I coached four sectionals and sat in all ensemble rehearsals, giving them advices. We had fun, I like working with teenagers closely (I like to try to connect with them) and I hope the students learned a lot in the eight weeks we worked together.
The most interesting thing was that most of the help they needed were about their bow use, where in the bow and how much bow they should play, and setting bow on a string before playing. That made me realize that many violinist, including myself, focus a lot on the left hand technique but the right hand (the bow hand!) is even more important, especially when it comes to orchestral playing.
So, here is my secret weapon... frog stickers! To remind kids play at the "frog" of the bow (near the bow grip, to play strong), I use those. I also have "tip" stickers (money stickers) for the opposite reminder.
