In the spring semester, I teach a class in secondary trombone for music ed. majors. As I go over the basics, I find myself double-checking my trombone majors for those little basic details.
Here's one that comes up at times: slide grip. Some of my students end up holding the slide in some odd way other than at the pads of the finger tips. Of course I point this out and some of them ask, "What does it matter? This way is comfortable."
Here's a new explanation to consider: when you write with a pen, don't you use the tips of your fingers for fine control?
Try signing your name by holding the pen closer to your knuckles instead. How does it look?
How would John Hancock's signature have looked had he been holding the pen close to his knuckles.
