I bet ppl are going to start inquiring now LOLOL!
You're right about that. Well, here's my thought:
I am somewhat aware that most horns and stuff of that nature are designed in flat keys. Considering that jazz was predominant from the early 1900s to the 60s and 70s, the horn players, like Parker, Miles and Trane, and big band leaders, like Duke, Count Basie, Calloway, and McShann, were writing their music for who…their horn players.
So you have players like Maceo, who grew up in that era, went straight from being a premier player/music writer for James Brown (a major foundation of funk music) to become a premier player/writer for somebody like George Clinton (P-Funk). Just like Herbie Hancock (grew up in that same jazz era). He play piano but he was hired by Miles, a horn player, and played to the fit the style of Miles.
So, by the mid-80s, we got rid of the horn players but we did not get rid of their grid. It is ingrained into us, we were born into it. When we were born, this is what was happening around us in our environment.
Just about all black music comes from this ‘jazz’ pot. This is where our ear comes from, our flavor, our style – everything. Everything that we are playing, writing, listening to, are based off the same platform as the horn players in the past – minus the horns.
I’m sure somebody thinks this is stupid but it’s “Just my opinion…”
