 Some noted brass pedagogues prefer to instruct the use of the embouchure from a less analytical point of view.Arnold Jacobs, a tubist and well-regarded brass teacher, believed that it was best for the student to focus on his or her use of the air and musical expression to allow the embouchure to develop naturally on its own.Other instructors, such as Carmine Caruso, believed that the brass player's embouchure could best be developed through coordination exercises and drills that bring all the muscles into balance that focus the student's attention on his or her time perception.
