'Hound Dog' took like twelve minutes. That's not a complicated piece of work. But the rhyme scheme was difficult. Also the metric structure of the music was not easy. 'Kansas City' was maybe eight minutes, if that. Writing the early blues was spontaneous. You can hear the energy in the work.
I hope everyone that is reading this is having a really good day. And if you are not, just know that in every new minute that passes you have an opportunity to change that.
