I say sit or stand, whatever feels better. I never saw sonny terry, lightning, champion jack dupree, louisiana red, stand when I played with them. I use to stand most of the time when I had a real band behind me. It was the monkey see, monkey do, knee jerk reaction. Since going to a 1 man band I sit out of necessity. I realize I prefer to sit. I sit all the time I play at home. I began as a sitter and I see no difference in my harp tones, voice either way. I will stand when I sit in with another band just for the freedom of being able to move around and the band still keeps playing! Blow hard, soft, tongue block, lip it, whatever that makes you feel good. That is where good music comes from. Sometimes I laugh when I read threads that go into minute detail about how to sing, blow, etc. It is like having someone pose for a portrait- very unatural because they are thinking all the time not to move
