But first, a little context and history...

Jazz was forged in the creole crossroads of late-19th-century New Orleans, where ragtime's syncopation met the blues' bent notes and brass-band discipline met funeral-march grief. It was the first music to treat improvisation not as ornament but as the point.

To improvise is to compose at the speed of feeling. The theory — ii-V-I, the modes, tritone substitution — is not a cage but a vocabulary. You learn it so thoroughly that, in the moment, you forget it and play what you hear.

For the adult learner, jazz offers a particular gift: it rewards a lifetime of listening. The forty years of records you already carry are not a deficit; they are the raw material.

“Jazz is the sound of practice forgetting itself.”
