On my way to teach a bunch of kids that really have trouble reading music... Don't get me wrong they're a great little bunch of violinists but they really have trouble sightreading.
So why do we hold such value in written music? If it weren't for the fact that they are meant to be taking grade exams fairly soon I would seriously consider scrapping written music altogether and teaching them by ear... More fun... Easier and allows you to concentrate on what is important, that is actually playing the violin.
I think in some ways it can get in the way. Then again, as a Classically trained violinist who plays in Orchestras and chamber groups (sometimes with very little rehearsal) music is vital for me.
For working out the wishes of Composers long dead it's great.
But for new music? The cutting edge? Is it just a waste of time?
