Yamaha recorders from the 30 Series are specially designed for beginners. Offering the ideal amount of air resistance for easy control of the tone, they also feature the kind of accuracy of intonation you would expect to find on more expensive models. Although other plastic recorders may have a similar appearance, Yamaha's ABS recorders are a step above the standard. For the advanced player, the arched windway, which is characteristic of the 30 Series, offers improved breath control and a clearer tone.
