Kawai Master Series MS134 Upright Piano

The Kawai Master Series
A Serious Alternative to a Grand Piano

At Bonners, we are proud to be among a select number of UK showrooms offering the opportunity to experience the Kawai Master Series in person, so you can hear and feel how these exceptional uprights redefine what’s possible in an upright piano.

At the top of the range sits the MS-134, Kawai’s flagship upright piano. At 134cm tall and weighing 332kg, it is built with six back posts to handle increased string tension, delivering outstanding power, projection and tonal depth. For many pianists, this is as close as an upright can come to the experience of playing a grand piano.

The wider Master Series range follows the same philosophy. These are not uprights designed as a compromise, but instruments created for players who want the depth, control and tonal richness of a grand in a more practical, space-conscious form.

Drawing on the design and craftsmanship of Kawai’s flagship Shigeru Kawai grand pianos, the Master Series incorporates premium features such as hand-wound bass strings and beautifully finished bird’s-eye maple interiors. The result is a range of upright pianos that deliver a level of performance far beyond what most players would expect from this style of instrument.

The Feel and the Sound
One of the defining characteristics of the Master Series is the Millennium III action. Constructed using ABS-Carbon, it offers a light, precise touch that remains consistent over time, regardless of changes in temperature or humidity.

Across the range, you’ll also find a true sostenuto pedal, something rarely seen on upright pianos, allowing for greater control and a wider range of repertoire. Internally, features such as mahogany hammer mouldings and premium Röslau “Blue” strings contribute to a warm, expressive tone, with clarity and refinement across the full dynamic range.

Built for Long-Term Performance
The cabinetry reflects the same level of thought and quality as the internal components. With a grand-style opening lid and a substantial, solid construction, these instruments are built to perform consistently over many years.

Kawai has even included a built-in thermohygrometer within the accessory box, helping you monitor the environment around the piano and protect your investment over time. It’s a small but thoughtful detail that reflects the level of care behind the design.

Why Choose the MS-134?
While every model in the Master Series offers an exceptional playing experience, the MS-134 stands apart as the most powerful and expressive instrument in the range.

With its increased height, enhanced cabinet design and structural strength, it delivers a deeper, more resonant bass, greater projection, and a wider dynamic range. For advanced players, teachers and serious enthusiasts, it represents the ultimate upright piano within the Kawai range.

Experience It at Bonners
The Master Series, and particularly the MS-134, is something that needs to be experienced in person to be fully appreciated. The depth of tone, the control of the action, and the overall presence of the instrument are difficult to convey on paper or a website.

We invite you to visit one of our showrooms to spend time with the Kawai Master Series, and to compare it alongside a selection of grand pianos. Our team will be on hand to guide you, answer any questions, and help you decide whether this exceptional upright is the right instrument for your home or studio.
