@bdp24, thank you for the recommendation, I’ll check them out. But the only soul hit I’ve heard in 25 years is Leave The Door Open, by Silk Sonic. Coincidentally, it had a hip and complex chord structure for an RB tune. It was truly more complex than a typical RB tune, but that’s what you get when it’s produced by Bootsy Collins and Bruno Mars, an exceptional musician who plays multiple instruments.
You’re pointing out exceptions to the rule. Miles popularized modal music in the very late 50’s. Miles, I believe, got the idea when he was visiting Paris, and asked to create a film soundtrack for a popular French film while he was on tour. This laid the groundwork for his musical comeback. The rest is history.
But anyone who knows jazz knows that modal music isn’t the norm. And even so, isn’t Miles modal album, Kind of Blue the greatest selling jazz music LP ever created? Of course it is. It’s been an entry to jazz for countless people. Yet, Trane, Cannonball, Evans, Chambers, the 18 year old Jimmy Cobb, and Davis created an LP that is still selling today, 75 years after it was created. So much for simple modal music.
I love Classical music! But it doesn’t have the complex chord structure as most jazz. But it couldn’t have, for it was Duke Ellington and Charlie Parker who popularized playing plus Eleven Thirteen chords. Still, Classical music is it’s own genre. And that’s because it’s roots aren’t based upon the blues, which wasn’t created until the 17th century when African’s were forced to come to America and the Caribbean. Without the blues, there is no jazz. As much as I love Beethoven, Tchaikovsky, Ravel, who truly bordered playing jazz chords in a few bars, Classical is just that, Classical. Which is more complex? That’s a column left for an entirely different thread. But ask the question. Can jazz players play Classical? Yes, so many came to jazz with a Classical background, Oscar, Jarrett, Evans, etc. But how many Classical musicians can improvise?
