I feel that including that information here, for free, where others have paid for it, is a conflict of interests. But there is a range related subject which I do not cover enough in that book. That is the subject of familiarity. I do discuss it in my book, but only in passing. Here I will cover this subject more completely.
Familiarity plays a key role in a great many aspects of music and trumpet playing.
Certainly it makes sense that we do things better when we are more familiar with them. If you play a song once and then try to perform it, you will not sound nearly as good as if you have been playing that song for ten years of your life. If you have a piece of music which requires double tonguing and you have only tried to double tongue once or twice before, then you won't play that piece as well is you would if you have been double tonguing for many years. A lot of things in music are this way. That's why repetition is so extremely important.
