People have their own interests and they want to play a certain kind of music. People want to play in orchestras. They want to play on Broadway. Those that want to play traditional jazz and have no interests in the ideas of improvisation. So in spit of the fact that there are fifty violin players, you might only narrow it down to ten and within those ten, there might only be three who have the right kind of background and credentials to deal with what you need to deal with. Everybody's got their own special thing that they are after and a lot of times you don't have time to be training people.
