At least from where I attended school, things do not appear to have changed much in the last 40 or so years. I attended an elementary school way out in the sticks, as we used to say. We had two grades in a classroom, and a total of three teachers in the school. A visiting music teacher dropped by twice a week, but she only taught stringed instruments. The classroom teachers organized the students into a choir, and we sang songs a couple of times a week. I couldn't join a band until I entered the 7th grade and got bused "into town" to attend junior high and high school. In junior high, my band director was a French Horn player, and my high school band director had at one time played cornet. He had not touched a horn in years to actually play one. Neither of these teachers ever gave me a single pointer about how to play trumpet. They did, however, teach me a great deal about music appreciation. In high school we also had a symphony orchestra, whose conductor played both sax and violin. He taught me more than all the other teachers combined. He made us listen to ear training tapes every day. He made us sight read every day. He made us learn scales. Etc. And he not only taught orchestra, he also lead the stage band. He taught me how to improvise, such as I do. He was a great teacher. But he couldn't teach me much about trumpet per se, because he was a reed player. If it had not been for my self-taught Dad at home, who showed me what he could, I probably wouldn't have stayed with trumpet at all. But Dad taught me how to count, how to finger the notes, and saw to it that I practiced. Come to think of it, he taught me how to transpose also. He used to make me play out of a church hymnal all the time and transpose the music by sight. Mostly what he taught me was to practice each and every day-a valuable lesson. And he bought me a set of Mendez playing Arban single tongue exercises, which I used to play along with every day, when I was 10 or 11 years old. And he bought me a ton of Mendez solos (every time Mendez came out with a new album) to try to play by the time I was 12 or 13. At least he set some pretty high goals for me to try to reach. But my band directors just took advantage of what I was learning off campus and of my practice habits. They surely did not contribute anything to my trumpet knowledge. I think band directors had better discipline, and demanded more from students in band, when I was in school. We played some pretty hard music back then. But at least in my case, they didn't really teach you how to play your instrument. You had to have an outside source of instruction for that. Fortunately, when I got to college, I had an excellent instructor.
