Good websites for studying jazz?(r/Jazz)
Learn how to use google site search to search those forums for topics that you’re currently working on.
musictheory.net – use the lessons and exercises because you have to know the basics of reading and memorize the key signatures, etc.
I urge you to check out Hal Galper and Mike Longo’s books/videos. They are at the forefront of Jazz Education and their material is a rite of passage for beginning jazz musicians.
Here’s a playlist of Galper’s masterclass videos: www.youtube.com/playlist?list=PL7iWyGibrnPOQPEuUL4…
The best general jazz chord-scale theory text I’ve seen (I’ve seen them all) is probably the Berklee book,
Chord Scale Theory and Jazz Harmony;
However, even better would be the Bert Ligon books, because they go into more detail about how to actually put it into practice:
Connecting Chords with Linear Harmony
Jazz Theory Resources Volume 1
Jazz Theory Resources Volume 2
Comprehensive Technique for Jazz Musicians
P.S. this subreddit is geared more towards jazz listeners and may not have that many musicians.
