Many years ago I was told by one of my teachers to get a copy of the book Stick Control by George Lawrence Stone. Although I found at the time some of the stickings useful, I actually found the work quite boring. The reasons for this were that I (on anybody else for that matter) didn't know how to use the book, and also that everything eminated from the snare drum (which I must add is important, but with a difference).
The book, at the time, was known as one of the Berklee Bibles and it compares in degree of difficult with the Arban tutor for cornet (ask any cornet player!). If you don't own a copy of this classic book, I thoroughly recommend you treat yourself to one. I would like to share with you some of the possibilities of this fascinating book if you have not thought of it already.

I am not saying "this is what you have to do". They are only ideas. The important thing is that if you are into something go and paint your own pictures.
