Throughout grade school and high school, I was fortunate to participate in quality music programs. Our high school had a top Illinois state jazz band; I also participated in symphonic band, which gave me a greater appreciation for classical music. It wasn’t enough to just read music. You would need to sight read, meaning you are given a difficult composition to play cold, without any prior practice. Sight reading would quickly reveal how fine-tuned playing “chops” really were. In college I continued in a jazz band and also took a music theory class. The experience gave me the ability to visualize music (If you play by ear only, you will never have that same depth of understanding music construct.)
Both jazz and classical art forms require not only music literacy, but for the musician to be at the top of their game in technical proficiency, tonal quality and creativity in the case of the jazz idiom. Jazz masters like John Coltrane would practice six to nine hours a day, often cutting his practice only because his inner lower lip would be bleeding from the friction caused by his mouth piece against his gums and teeth. His ability to compose and create new styles and directions for jazz was legendary. With few exceptions such as Wes Montgomery or Chet Baker, if you couldn’t read music, you couldn’t play jazz. In the case of classical music, if you can’t read music you can’t play in an orchestra or symphonic band. Over the last 20 years, musical foundations like reading and composing music are disappearing with the percentage of people that can read music notation proficiently down to 11 percent, according to some surveys.
