I've just started the trumpet in my later years (56), having taken lessons for about 2 and a half months now and away from music for 40 years (recorders in chamber music group when I was young). Challenging to say the least but really enjoying it. I'd like to calibrate my progress, never having realized beforehand that going up the staff is a climb. I am fairly comfortable at this stage up to "C" on the staff, up to "B" on the staff is very solid, and can hit "D" on a good day when my chops aren't too fatigued. I have no feel for how I'm doing in my two month "journey", except my trumpet teacher says I am doing very well, with steadily improving, consistent tone. Any thoughts from all you "pro's" would be appreciated.
