I cannot answer to you well... it was a joke:)
I come from the North of Italy and people here is totally different in character. Unfortunately we are not so fatalist and open.
I think that weather and, as Carlo said,their history are the responsible of their way of doing.
If your gestures look so vague and polysemantic it is probably because you use only the hands. They use all their body and, above all, eyes and mouth...so funny!
The same is for music. I love it because is joyous or tragic. They don't know "gray" (stereotype). Tarantella is a South Italian country dance (XVII century). We never listen to it but I think is OK.
