The world’s most popular upright.
Precise, ultra-responsive touch, clear, full-bodied tone and a reputation for reliability have made U Series pianos the choice of professional musicians, conservatories, teachers, students and music lovers, the world over. Add to that our legendary attention to every detail of every piano, and it’s no surprise that the U Series has been the world’s most popular upright for over half a century.
Small space, big sound
The U Series soundboards and ribs are crafted from solid spruce that has been hand selected at our Kitami Mill in Hokkaido, Japan giving these pianos a richer, more resonant voice and evenly balanced timbre across the entire keyboard.
Back posts, forward thinking
Years of cutting-edge research, including our proprietary wood-drying process, result in back posts that maintain their shape, strength and resonance for years to come.
Advanced V-Pro frame
Yamaha was the first company to use an advanced Vacuum Shield Mold casting technology called V-Pro to create a stronger, lighter, more durable frame. Every U Series piano features a full-perimeter frame built to our exacting specifications at our Iwata Forge in Japan.
Specially designed hammers
U Series hammers are crafted of the finest materials and painstakingly designed for each model to provide optimum tone, response and a lifetime of musical enjoyment.
Hand wound bass strings
Yamaha artisans in our factory in Kakegawa, Japan oversee the winding of pure copper and adjust the balance and tension of each bass string to the exacting standards and sound profile of every U Series piano.
The world's first aluminum action rail
Often copied but never equaled, the patented Yamaha aluminum action rail helps assure our piano keyboards are resistant to tiny fluctuations in humidity and temperature over time.
Inspired by our grand pianos, our damping mechanism prevents the fallboard from dropping abruptly, guarding against accidental injury or damage.
