Since school started and the entire family is back on a regular schedule, I've been able to practice for close to a solid hour, Mon-Fri, in the mornings between dropping off the squids and hitting the office. I've been working a lot in Arban's, along with some of Clarke's Technical Studies. Working on a lot of stuff, setting aside specific days to hit intervals, tonguing, and one day a week for range/high notes, but I find that a significant hole in my game continues to be endurance. My question is two-fold. First of all, am I even putting in enough practice time to build endurance? If so, are there specific exercises or practice techniques that can foster endurance? As an aside, I just 'discovered' the Characteristic Studies in the back of Arban's, and those are quite fun and challenging. Page 295, I believe. Not sure why, but I somehow don't believe I'd ever seen them before last week. Weird.
