The links to the LEFT will lead you to some interesting information and web sites for learning to play and teach the trombone. Though I've divided the material into "tenor trombone," "bass trombone," and "jazz trombone," you will find useful material in each section. Some of the material gets pretty advanced so search for exercises that fit the level of your playing or teaching. As usual, don't hesitate to contact me with questions or if you need clarification. If you don't find the material you want or that addresses the problems you are having, let me know what the problem is and I'll write some material for you that will addresses your specific issues.
