Yeah... there are good threads on those topics, already

CLAPPING

Any gospel song with a strong beat is likely to get people clapping in rhythm, whether it's white or black gospel. The real difference is that often in black gospel, people clap between beats, too. I hear tell that's called polyrhythmic clapping, and is an old African form of keeping rhythm. It can be very complex. When I sing in the Men's Chorus, my friend Frankie usually claps between beats... I'll have to ask him about that... it's a very old form of keeping rhythm and I notice he's usually the only one in the whole chorus who does it. I'm especially aware of it, because we always stand next to each other when we're singing. On songs that are in three quartet time, people clap on the second and third beats, which I haven't heard in white gospel. Toss in moving back and forth in rhythm and it's a wonder I can even sing..
