Description Product Description Annealed bell gives this baritone sax the highest quality sound. Tilting style low Bb spatula keys The position, height, angle and shape of the left-hand pinky keys have all been carefully redesigned to provide extraordinary comfort and quick response. Three-vent octave mechanism A feature exclusive to Yamaha saxophones, the three-vent octave mechanism eliminates fuzzy, unclear tones when playing G, G# and A with the octave key. Acoustic annealing of the body The brass used in Yamaha professional model saxophones goes through an original acoustic annealing process that gives the metal optimum density for superior tone. In conjunction with other advanced design features, acoustic annealing also contributes to precise resistance and playability. Adjustable thumb rest All Yamaha saxophones feature an adjustable thumb rest to allow for precise and comfortable hand and fingering position. Refined key shape and dimension Yamaha saxophone keys are not simply shaped and positioned according to mechanical necessity; the entire system is designed from the player's perspective, with emphasis on comfort, speed, and overall playability. The natural feel of the keys eliminates the need to adapt to an unnatural or uncomfortable key layout.
