In a piano, different types of wood are needed (a.o. Maple, Mahogany, Oak, Spruce …). The instrument is a very sustainable product. It can last for several decades and can be used by several generations. So, we find this a very sustainable use of wood. However, as a piano manufacturing and retail company, we find it also our duty to help to keep the wood and trees population on an even higher level. Prevent global warming is the duty of everybody. Music can get us through everything, but not through global warming!
