Whenever knowledgable pianists discuss which brands of upright pianos are the finest in the world, Kawai K Series Professional Upright Pianos are always part of the dialogue. That’s because the K Series pianos provide a truly exceptional combination of excellent touch, outstanding tone and unrivaled stability that will impress any discerning player or performer. Most piano brands can make bold claims about stellar touch and tone. But the key attribute that most pianos buyers overlook is “stability” — the instrument’s ability to maintain high-quality touch and tone over the course of time.

A half-century ago, Kawai realized that the prime cause of piano problems was the use of wood in all parts of the piano’s internal action. Wooden parts would shrink, swell and warp — which negatively affected both touch and tone. To prevent such problems, Kawai pioneered the use of modern composite parts that are virtually impervious to the shrinking, swelling and warpage issues that cause piano performance to decline. The renowned Kawai Millennium III Upright Action with composite parts is the chief reason why K Series Professional Uprights maintain exceptional tone and touch over time — and why they are continually counted among the world’s finest upright pianos.
