Can anyone give me a little advice on using the third valve slide compensator, I have very small hands and no matter what my teacher and myself try I can't seem to get it moving. I am very happy with my teacher, as comeback player I'm progressing nicely. The problem is when I was first playing the Cornet my then teahcers attitude was " What do you want those modern things for use your lip" and I can to a great extent on the Cornet. Even when I first got manky school instruments the third slide ring was often missing. At the moment I have my third finger in the slide ring but when I try to move it I often end up moving the whole horn (the slide is plenty free). Obviously I know when it should be used its just the doing it.
