1. You are a genius and a talent.
2. How can anyone play all these instruments at a high level.
My answer to number two is I play them well and I know how to perform just about all the technical things that a top notch player can perform. Even more important for the student is that I can teach them at a level of the top ten percent of the teaching scale. I taught a student on one of my weaker instruments how to play better than I did. This is possible because I know what to do but I just didn’t play this instrument as much as this student through the years but could do a lot more on my stronger instruments. I do not play all the instruments at a level that a professional person playing one instrument several hours a day all their lives can. An example of how this works is an olympic teacher teaching world class performers because he was there and knows what to do form the past. The student is a better performer than the teacher because the teachers has retired from competition and the student is the one that is practicing the routines at that point. This early twenties student lived and breathed playing his instrument. He practiced playing 3 hours a day. He was a student that was with me for five years and had already had been playing on this instrument before coming to me. I eventually decided to recommend him to a world class player that I knew on the instrument he played. When I asked him how things were going a few months latter he told me that lessons were going well and that this teacher told him that he was one of the most advanced players he ever taught that came from another teacher. There is a good chance that this teacher could not have done the prior work I did as good as I did. I am very successful at what I do due to my lessons plan, foresight, hard work, at improving what I do and my creativity as a player and teacher.
Many of my students through the years took lessons on two and three instruments from me and continued to play them after they stopped their lessons.
