4 things that I learned are:

1. That they put goat skin over for the drumming cloth thing

2. Balkan maple wood is a very dense wood

3. Pau Brazil is used for making violin bows but it is very wasteful since one violin bow needs a kilogram of wood.

4. Honduran Rosewood is the perfect material for xylophones and calves.
