The sound barrel is made of wood material, good sound barrel = good sound quality
Nowadays, mahogany is no longer difficult to obtain, and the mystery of good wood from felling to becoming a piano lies in the process of wood dehydration. Those that seem to have good quality and excellent dry humidity are the products in the roasting room, and our mahogany only uses the sun and wind to let the wood slowly lose its moisture, just like a good wine.
