For those who have a difficult time focusing on their trumpet studies during the summer months, I have a suggestion that has worked for me for years. If you're a "half-full" kind of person, list all of your abilities on the trumpet broken down into 15-20 categories, with the strongest being number one and the 20th being your weakest. Turn the list upside down. Take the first five and make them your list for the summer. Those five things will be what you focus on when choosing etudes and exercises. Don't worry, you won't lose your original top 5. They will always remain. You might have to blow some dust bunnies off, but fear not, they will be there when you need them. If you're a "half-empty" person, go straight for the jugular and pick your five weakest abilities. That is your list for the summer, so get to it! The point is that most of us practice in the same order every day, month after month and most times never make it to those last 5 or so things on "the list". Those are parts of our playing that are probably available, but could stand some polishing. This is a way to constantly polish our playing. Every summer the list will be a bit different as awareness shifts and different challenges arise. That is a good thing and keeps us from getting stale. It also allows us to check in with our playing more objectively. Just thought I'd share.
