rowuk sez: I find all of the advice in principle good, but none of it will probably help here. The chances of someone figuring out how to "structure" their development all by themselves with no formal trumpet training, is plain old pot luck. ----------------- Unfortunately, its just plain old pot luck even with formal training. You know as well as I that there are tons of people who have been exposed to formal training that still have no structured method of keeping in shape (which means they basically possess minimal skills). Life and learning is one big bowl of pot luck.
