Your ignorance of musical forms is somewhat troubling. The blues are, of course, an important and storied part of our musical heritage, but you appear to be completely oblivious of the reds, lavenders and oranges.
There is not sufficient room here to go into these musical forms in detail (see Malcolm W. Cornett,
Multicolored Music, Simon & Schuster, NY, 1922; and Ralph J. Pimpleforth,
My Mammy Sang the Oranges, Bluth & Grabble, Miami, 1945.)
Most shocking, I find, is that you seem not to be familiar with the greens, which many cleaning women have sung while mopping the floors of rich people. An example:
"I got the wring-wrung greens,
I'm as green as I can be.
I got the wring-wrung greens,
I'm as green as I can be.
My man done went and left me,
I'm greener than the deep-green sea."
Why do people throw confetti, when it only litters the streets?
