Over the past several months we have been working on the jazz history diagram, and we're scheduled to complete it in 2019. You have to a website member to sign in, so many of you can't see it currently. But here's the topics we've covered so far:
Development of bebop
Early days of soul jazz
That puts us around halfway through the project so far. We plan to add some links to soul jazz recordings, perhaps some links even to music theory posts along the way, and then we'll hopefully finish the diagram - even possibly by the end of the month? We'll see.
Once it's done, it'll become public, meaning that everyone will be able to view it.
