- Advanced saxophonists looking to move into a professional baritone saxophone.
- Conservatoire and music college students requiring an instrument capable of supporting advanced study.
- Experienced amateur players who want to invest in a high-quality baritone for long-term use.

Although the BWO1 sits at the entry point of Yanagisawa's professional WO baritone range, it is designed without compromise in the areas that matter most to serious players.

Our experience
Yanagisawa has built its reputation around precision saxophone manufacture, and the BWO1 demonstrates the company's detailed approach to mechanical design. Rather than simply scaling up the construction of a smaller saxophone, Yanagisawa has developed the WO baritone range around the particular demands of the instrument, including its low register, keywork geometry and tonal stability.
The BWO1 incorporates several practical refinements that are particularly valuable on a baritone saxophone. The C♯–B♭ table-key linkage, refined low-A mechanism, redesigned side-key arrangement and relocated strap-ring position are all intended to make the instrument easier to control and more comfortable to play.
For players choosing a professional baritone, consistency is just as important as tonal character. The BWO1's combination of precision keywork, responsive brass construction and Yanagisawa's established manufacturing standards makes it a compelling option for musicians looking for an instrument to keep for many years.
What makes the Yanagisawa BWO1 different?
The BWO1 benefits from the engineering developed for Yanagisawa's modern WO Series baritone saxophones. The tonehole dimensions and layout have been refined to promote a more balanced scale, helping provide stability across the instrument while maintaining the projection and tonal flexibility expected from a professional baritone.
The mechanical design is another important part of the BWO1's appeal. Its C♯–B♭ rocking linkage facilitates smoother fingering, while the fluororesin-coated octave mechanism is designed to minimise unwanted movement and maintain smooth octave-key operation. An adjustable vibration-damping bar on the right-hand F♯ key also helps control sympathetic vibration and support stability in the lower register.
Yanagisawa has also paid close attention to player comfort. The genuine mother-of-pearl key touches provide a natural surface beneath the fingers, while the metal thumb hook and brass thumb rest are designed to support comfortable playing and allow the instrument to resonate freely.
The result is a professional baritone saxophone that balances the substantial, powerful voice associated with the instrument with the precision and responsiveness needed for demanding repertoire.
Professional Japanese craftsmanship
Yanagisawa has specialised in saxophone manufacture for generations, with its instruments recognised for precise construction, consistent keywork and carefully considered mechanical design. The BWO1 is part of the company's professional WO Series and embodies this approach through its brass construction, lacquered finish and extensive attention to detail.
The instrument features pointed pivot screws for precise mechanical alignment, needle springs for responsive key action, double-arm keys for added stability and a tri-point bell-bow brace designed to provide structural rigidity. Waterproof pads are used to support airtight sealing and consistent response, while the octave mechanism incorporates fluororesin sleeves to promote smooth operation.
For the player, these details add up to an instrument that feels controlled and dependable rather than simply impressive on paper. Whether used for extended practice, rehearsals, ensemble playing or professional performance, the B-WO1 is designed to offer the consistency expected from a modern professional baritone saxophone.
