Any of you that have studied music know which instrumentalists spent the most time in the shed - and it for the most part was not the trumpet players. If I think back to my education, the jazz wind players with the most time were the saxophones and SECOND trumpet players. Scales, intervals, patterns. The classical musicians were lead by the clarinets and flutes in practice time. The trumpeters were way down in hours compared to them. In many cases the trumpeters were gigging more which in my book is different than playing exercizes to "master" the instrument.
