K in the pink shirt, H in her black leotard. After H's class, we were waiting for S and K and A in the lobby when we heard a loud caucaphony in one of the other gyms. There was a drumming troupe there, vigorously beating their drums while women strutted around the gym, warming up. Hannah wanted to go in and watch, so we did. After K's class, she came in too, and they both joined in the dancing. It was an African dance class. The dancers would group together (not sure if they were grouped according to ability or experience or not), and they would follow one of the three instructors across the gym emulating their dance step. The lead drummer would play a certain signal when it was their turn to move across the floor, and then again when it was their turn to stop and walk back to the starting point again.
