Yamaha 20 and 30 series recorders are designed to provide a perfect start to anyone's musical education. They offer an ideal amount of air resistance for easy control, and feature an accuracy of intonation you would expect to find only on more expensive models. Though other plastic recorders may have a similar appearance, Yamaha ABS recorders are truly superior instruments. The 20 series, easy to play throughout their entire ranges, are primarily intended for beginners. 30 series recorders, which feature an arched windway for improved breath control and clear focused tone, are for more advanced players.
