I have been told many times (by reputable teachers) "the chops are like any other muscle - exercise every day and they will become stronger" and yet this appears to be a complete fallacy. For a start, the chops are not like any other muscle. More importantly, every athlete can tell you that in fact if you want to build up a muscle for either endurance or strength, recovery is just as important as exercise. Any sports training programme that only includes hard effort every day without adequate rest periods will only result in overtraining and underperformance. Is this method based on the assumption that no-one is diligent enough to actually practice hard every day? Further to this, in most physical performance disciplines it is usually accepted that preparation must involve working towards defined peaks or goals within a 'season', building up through phases of overloading and then tapering off to freshen up and fine-tune for the event. Most brass bands that I know of simply prepare more and more feverishly leading up to an event, finishing off with a third accepted no-no... Preparing for a contest by practicing once per day, in the evening, and then throwing that out on contest day by playing twice, in the morning and afternoon (or whatever). All method books I have read or heard about seem to ignore at least some obvious scientific fact in order to strongly push one particular philosophy - always based on small refinements to some accepted wisdom or other, and usually endorsed by people whose (undoubted) talent appears to be largely natural rather than based on rigid adherence to the method in question.
