Singing about your sadness unburdens your soul. But the blues hollers shouted about more than being sad. They were also delivering messages in musical code. If the master was coming, you might sing a hidden warning to the other field hands . . . The blues could warn you what was coming. I could see the blues was about survival.
B. B. KingWhen I sing, I play in my mind; the minute I stop singing orally, I start to sing by playing Lucille.
