ORCHESTRA?!

Well seeing as how I've ran out of other topics, such as running and tennis, I've resorted to talking about orchestra, and playing the violin, and how that relates to physics.  Well, everyday in class our teacher tells us to warm up by stretching with our instruments.  We have to lift them up, left, right, and even twist them around to make sure we don't pull a muscle while we play (cause those hurt).  Sometimes our teacher will tell one of us that we don't play with enough power, and she will grab our bow and push down on it with extreme force, sending clouds of rosin into the air.  Let's see, what else...  Oh yeah, often times when playing fast music, the velocity of your fingers must be very high, yet constant, otherwise your timing will be off.  Shifting up and down the fingerboard also changes the displacement of your hand, but it can be difficult to make sure your displacement is a certain distance every time.  Although the movement of your fingers and your bow can be very minimal at times while playing the violin, it takes great accuracy and precision to master such an instrument.  All other instruments also require the same type of precision in order to be played well, which makes playing music such a wonderful joy (hahaha).
