Key of A. Each instrument has a select handcrafted Grenadilla wood body and sculptured silverplated nickel silver keys. Toneholes are individually hand-tapered and undercut for optimum tone quality, intonation, and uniform response throughout the instrument's range. The taper inside the new bell design is more open to provide for a round, full sound. Created for players who prefer a bright, full sound, with a clear, focused tonal center. The Yamaha V-Series clarinets represent the very pinnacle of the clarinet making art. They are handcrafted from a select grade of Grenadilla wood with uniquely contoured inner bore configurations. Hand-tapered undercut toneholes provide outstanding intonation and response. V-Series clarinets incorporate a unique silverplated nickel silver alloy for key construction which adds to the resonance of these fine instruments. V-Series clarinets are instantly recognizable by the "V" emblem on the upper joint. All Yamaha wind instruments come with a limited 5-year warranty.
