if a newbie doesn't live in an urban area of the USA what alternatives are there to learn some foundation and get started?
Before the internet the alternative was Jazz records, a phonograph, and the will.
Back in the text-only internet, Marc Sabatella's Jazz Improvisation Primer Gave me a solid foundation
That sounds more like Rick Beato's older content.Where's the stuff about uses of the whole tone scale in classic rock and why phrygian mode crushes everything?
