I played Trumpet obsessively for about 8 years (was in 4 bands and MN Brass Senior Drum and Bugle Corps) Then I got married and had kids and playing became a thing of the past. A few months ago I decided I was going to get back into the swing of things and started practicing religiously every day except I found that my lips got sore (even cut on the inside from pressure against teeth) and the musculature support for the embouchure just wasn't there. It's been about three months with an average of 1-2 hours of practice EVERY BLESSED DAY and I still tire and can't hit notes after a mere 45min to an hour of practice. . . I just don't know what to do to help increase endurance. I love to play and find myself pushing it because I still want to practice more. . . I don't remember going through this when I first learned to play way back when :-? Oh well Any tips or suggestions would be greatly appreciated.
