The Yamaha YRS-402 is a three-piece alto recorder from Ecodear™. This special plastic is an environmentally conscious variant in which part of the conventional petroleum-based material has been replaced by resins made from plant starch.
The special material of the YRA-402 has a much higher density than normal plastic. This gives these flutes a more centred sound, improved blowing resistance and easier response. These improvements make the Ecodear™ models sound even more like a wooden recorder. The wind tunnel of the YRA-402 B also has a more pronounced curvature and now meets the standard of professional recorders.
