Exclusive U Series Features
Advanced Scale Design
Refinements in all elements of sound production have given today’s U
Series a richer, more resonant voice with evenly balanced timbre across
the entire keyboard.
Soundboard and Frame
Special rib configurations add strength to the soundboard, while backposts
and other advances further enhance rigidity, resonance, and structural
stability.
Floating Support System (U3, U5)
A ‘floating’ attachment method, similar to that of grand pianos, allows the
soundboard to vibrate more freely, improving the depth and character of
bass and mid-range tones.
Specially Designed Hammers
U Series hammers use materials specifically selected for each model to
provide optimum tone production, response, and long-term durability.
Soft-Close Fallboard
A damping mechanism, formerly used only in grand pianos, prevents the
fallboard from dropping abruptly onto the keyboard, guarding against
accidental injury or damage.
Advanced scale design (U5)
A Yamaha Classic, Refined
Yamaha U Series upright pianos have long been a leading
choice for educational institutions, professional musicians,
and discriminating home pianists. Now, thanks to
comprehensive redesign, these Yamaha-standard
instruments are better than ever, with substantial
refinements in materials, construction, production processes,
and overall design. Today’s U1 and U3 models incorporate
an advanced scale design that improves tonal performance.
A floating support system improves the depth and character
of bass and mid-range tones in the U3 and U5 models, while
other modifications enhance strength and durability.
Incorporating a number of design concepts adapted from
Yamaha grand pianos, the U5 model has taken its place at
the very top of the U Series line.
