Larry, The BAS is as it was when it was published in 1987. As I pointed out it can be used with any band method book. Many band directors enjoy tailor making the BAS to the needs of their own program. This can be done in a variety of ways. The most common one is when the band director picks the page and exercise number for each Award. It can be made as easy or challenging as what is available. I have some plans to make the music theory more advanced on levels Five and Six. I would like to get the students involved in interval identification and basic chord ID also. We shall see!
