Yamaha's 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 one more expensive models. The 20 series, easy to play throughout their ranges, are primarily intended for beginners. 30 series recorders, which feature an arched windway for improved breath control and tonal expression, are for more advanced players.
