Years ago, Grandmas everywhere kept a large wooden spoon on the back porch next to the dishpan. When a hive swarmed, she would grab them and stand in the yard banging on the dishpan like a drum until the swarm landed. Anything can be used, as long as it makes a drum like noise. I used my hand on an empty cardboard nuc yesterday. That's all I had handy.
It was known as tanging, or drumming. Now there is another motion that has been dubbed drumming, so most call swarm calling tanging now.
That answers the drumming, but what is a s m a school?
