As I am teaching myself how to play it's difficult to learn certain aspects, and as far as slapping goes, I didn't even know it was possible on an upright until I heard some people talking about it and heard it in a recording or too. I assume it's completely different from slapping and popping on an electric, which I can do. Does anyone know where I can find an online video that has someone playing slap bass? I'd prefer it to be free to watch, but if theres no other alternative then I might have to do that. Thanks in advance.
