There a many (good) trumpet routines especially the Bill Adam routines in my opinion. But I decided to write a routine myself for my students (at the Amsterdam University of the Arts). I used some material from Herbert Clarke, Max Schlossberg, James Stamp and added some exercises I collected and composed in the past which I’m practicing on and off for 30+ years now.
I called the routine “The Magnificent 10” as a variation on another routine played by L.A. studio musicians like Gary Grant, Jerry Hey, Larry Hall, etc. So it has 10 exercises with some variations in it.The-Magnificent-10-Trumpet-Routine-1
