Yanagisawa SWO1 Soprano Saxophone

A professional soprano saxophone with a rich tonal core, precise response and beautifully refined keywork

The Yanagisawa SWO1 Soprano Saxophone is a professional-quality B♭ soprano designed for musicians who want exceptional control, consistency and a highly responsive playing experience. Made in Japan by Yanagisawa, the SWO1 combines meticulous craftsmanship with the advanced design principles of the WO Series.

Constructed from brass and finished in lacquer, the SWO1 produces a beautifully rounded yet focused sound, with a strong tonal centre that gives players excellent control across the instrument's range. Its fixed-neck, one-piece construction contributes to a direct, coherent response, while Yanagisawa's carefully refined keywork makes the instrument comfortable and intuitive to play.

The SWO1 replaces the highly regarded S901 and introduces a number of refinements developed for Yanagisawa's modern WO Series. Its re-engineered bore and tone holes, redesigned Front F key and refined table-key mechanisms are designed to provide smooth response, reliable intonation and fluid fingering for both detailed classical passages and expressive contemporary playing.

Who is this saxophone best suited to?

The Yanagisawa SWO1 is an excellent choice for:

• Advanced students looking to invest in a professional soprano saxophone.
• Conservatoire and music college students.
• Experienced amateur saxophonists seeking a refined, dependable instrument.
• Professional musicians who require consistent response and precise keywork.

Our experience

At The Wind Section, we understand that choosing a soprano saxophone is a particularly personal decision. The smaller dimensions and more concentrated sound of the soprano make factors such as intonation, resistance, response and keywork especially important when selecting an instrument.

Yanagisawa has established an outstanding reputation among serious saxophonists for the precision and consistency of its instruments, and the SWO1 is a strong example of that approach. It combines the refined mechanics associated with Yanagisawa with a responsive playing character that makes it enjoyable for extended practice, rehearsal and performance.

The SWO1 is particularly impressive for players who want a soprano that feels controlled and predictable without becoming overly resistant. The redesigned WO Series mechanisms and updated bore and tone-hole design demonstrate Yanagisawa's continued attention to the details that make a practical difference to the player.

What makes the Yanagisawa SWO1 different?

At the heart of the SWO1 is Yanagisawa's re-engineered WO Series bore and tone-hole design. This has been developed to encourage an even, smooth response while supporting accurate intonation, giving players a solid foundation from the lower register through to the upper range.

The keywork has received considerable attention too. The redesigned Front F key is intended to make fingering more natural, while the Right Side and Right Pinky key arrangements have been refined for improved comfort and control. The connected C♯–B♭ and C♯–B table keys help make movement between frequently used notes smoother and more fluid.

Yanagisawa has also incorporated a fluororesin-sleeved octave rocker to reduce unwanted movement and promote smooth octave-key action. Genuine mother-of-pearl key touches provide a naturally comfortable surface beneath the fingers, while the metal thumb hook and rest are designed to provide secure support without unnecessarily restricting the instrument's resonance.

Professional Japanese craftsmanship

Yanagisawa has specialised in saxophone manufacture for generations, with a reputation built around careful engineering, precision keywork and consistent production standards. The SWO1 brings these qualities together in a professional brass soprano saxophone designed for musicians who expect their instrument to perform reliably year after year.

Its lacquered brass construction gives the SWO1 a classic appearance, while the one-piece design and fixed neck provide a straightforward, direct playing experience. The instrument is supplied with a Yanagisawa ebonite mouthpiece and a fabric-covered wood-shell case with an outer pocket and backpack straps, making it well equipped for both everyday playing and performance use.
