Our intermediate clarinets incorporate many of the secrets we have learned from creating our Custom and pro models, and were designed by the same artisans. With bodies made of high-quality Grenada, they feature a dark, resonant tone and very accurate intonation. The silver-plated keys are hand-adjusted for an attractive and comfortable touch and they are available with 22 keys(457-22), 20 keys(457-20), or 18 keys(457-18)
