There are not such as stupid questions.
tarantella is a dance from Southern Italian culture. Its name comes from tarantula spider. It is a healing dance performed traditionally by women; its rhythm uttered from a large drum called Tammorra ( at least around Naples) is fast and hypnotic to induce the (often mentally) ill person in a state of trance and cure mental diseases at that time when science groped in the dark.
Even Bob Dylan wrote something about it following his passion for folk tradition.
