Ten (more or less) most important things I learned from other teachers, in no particular order.....
One should have “reverence” for every note. A quote from Uan Rasey, said in a lesson with Dusty McKinney
Lip bends, to help locate the center of the sound..... lip a low C down, then up again to where the air goes through the easiest and the sound is best. Then lip up a low C as best you can, and then lip it back down to where the air goes through the easiest. That’s where you’ll find the center of the sound. - Clifford Lillya
The shape of muscles formed underneath the lips should be an inverted “C”. This led me to develop the notion that we should think about having three “points of strength”. One at each corner of the lip, and a third which is located at the bottom of the chin. Imagine a string is attached to the bottom of the chin. On the bottom of the attached string is a weight, which gets heavier the higher you play. This is in order to keep the proper shape of the muscle structure. Essentially to keep the lower lip from rolling in, which is one of the things Phillip Farkas talks about in his excellent book, “The Art of Brass Playing”.
Organize your daily lesson routine and those for your students, and adapt any exercise to meet your needs. - Claude Gordon
“As you go up, stay down, and as you go down, stay up.” - Jimmy Stamp
from Tom Stevens - high standards
from Bob Karon - proper breathing techniques as taught to him by Arnold Jacobs.
From Rob McGregor - how to phrase. When we were both in college, Rob would play recordings for me of the great artists, and point out how someone like Maurice André could play such beautiful phrases.
From Frank Kaderabek - can’t be a first trumpet player and be shy about it!
Mannie Klein - have fun with life, and with music
Control the instrument, and not to let the instrument control you! For example, learn to play with and without vibrato - Timofei Dokshizer
Caruso Studies - one lesson with Harry Kim introduced me to the beauty and simplicity of these studies for help with upper register and endurance.
