I realize you should do what works best for you, but I'm curious to know what kind of warm up routine everyone here in the TM community does. Do you do the same one everytime? What do you focus on most?
I'll start off by saying I always try to start off just on the mouthpiece. I slur from a mid staff G whole note to an F# whole note and then back to the G. I then rest for a whole measure and do the same thing starting on an F# to an F, etc.
After I get down to the C# to C or so, I put the the MP in the horn and work on oter various slur methods ranging from low G below the staff to the G sitting on top.
Once I'm finished with several slur exercizes, I move on to double and triple tonguing; just a couple of the studies within arbans.
To finish the routine I usually end up performing some of the numbers in my clarke book, just to keep my fingers sharp in all of the keys I must play.
That's it; nothing to write home about. It has worked for me through my trumpet playing career... I'm anxious to know what you guys do!
EDIT: Also, sorry if this is in the wrong section. This looked like the most appropriate place to ask!
