The earliest memory I have of a zambomba (or friction drum) is of my uncle Pedro playing it in a very a-musical fashion while the rest of the family sang one of the four Christmas carols that constituted our repertoire.
So, what is flamenco? That’s a big question. Let me give you a brief-ish answer. Flamenco is folk music from Spain. It developed in Andalusia over centuries, and took its current form in the 18th century. Its origins are still murky, as there isn’t much documentation about the early forms this music took.
