Yamaha 400 Series Soprano Recorder
New recorder from Yamaha. Corn-based plastic. Earth friendly! Mouthpiece curved for more control and professional sound.
New Plant-Based Plastic Body
Bodies made of plant-based “Ecodear” plastic: the world’s first application of this material in a musical instrument.
Improved instrument performance
The change in material has resulted in a mellow, centered tone that is similar to that of wood recorders, plus improved breath response and high-register control.
Newly adopted plant-like colors
Bright colors chosen to elicit the image of plants such as corn and others have been used in the recorders and cases for the first time.
Plant-based plastic “Ecodear”
"Ecodear" plastic is a plant-based material created by combining polylactic acid (PLA)* derived from plants with other materials through an original Toray polymer alloy process, achieving characteristics that are similar to conventional oil-based resins.
* Plant-based PLA Compound Resin Plant-based PLA compound resin is produced from plant starch (corn is the main ingredient currently used) via a process that includes lactic acid fermentation and polymerization.
The "Ecodear" used in the YRS-401 and YRS-402B recorders is a compound of polylactic acid and ABS resin (3:7 ratio) that has about the same workability, durability, strength, and appearance as conventional ABS resin,
“Ecodear” is a safe material that has been used in home appliances, office equipment, and a variety of other items.
