The alto saxophones from Yanagisawa's WO Professional series offer a clear and bright sound, lightweight yet sturdy mechanics, and unparalleled ease of play. Made in Japan, these instruments cater to beginners, enthusiasts, and professionals alike, from classical to jazz.

Technical enhancements to the WO Professional series saxophones ensure impeccable intonation, improved projection, and increased uniformity across all registers. The brass used is more durable, and the keys have been redesigned and repositioned for optimal grip.

Adjustments made to the angles of the D# and low C keys allow for a smoother transition between notes, while additional reinforcements under the right-hand side keys provide a better playing feel. The key guards are soldered onto a single plate, enhancing resonance, and a new resonance plate has been added to the neck for a more centered sound.

The WO Professional series saxophones are renowned for their top-tier craftsmanship in their workshop in Japan. Yanagisawa's precise, robust, and well-designed keywork makes them the best saxophone manufacturer globally. Moreover, these instruments offer exceptional ease of play due to their new neck. The sound accuracy is impeccable, and all saxophones are meticulously adjusted.

The case provided with these saxophones is practical, well-made, and sturdy, ensuring optimal protection for the instrument on a daily basis.

However, it's worth noting that the sound of the WO Professional series saxophones might lack breadth, favoring a classical tonality. Despite this, these saxophones remain excellent choices for musicians seeking top-tier instruments.
