Yamaha Upright Pianos are the clear leader in Modern Upright Piano Design.
Every component in the Yamaha upright piano is built by Yamaha.
Yamaha Upright Pianos are built in Indonesia or Japan.
The Construction of a Yamaha Upright Piano
One of Yamaha’s biggest innovations for the piano action has been the Aluminum Alloy Action Rail.
The Action rail is the foundation of the piano action.
88 individual hammer flanges are attached to this rail, previous wooden models from other makers would be susceptible to humidity and warping.
The essence of the Piano is created at Yamaha’s Kitami Mill in Hokkaido, Japan.
The Spruce is selected by seasoned professionals, only the best grades are allocated to the construction of the Piano Ribs and Soundboards.
The Ribs and Soundboard is what amplifies the sound from the strings via the Bridge, thus the reason on why Yamaha Dedicates such great care to this crucial component of the piano.
The back posts are an integral part of the pianos construction, it is the foundation for the plate and is a conduit of resonance and sustain.
The Back Posts are attached to the back beam which houses the pinblock and the bottom beam which is attached to the bottom of the pianos harp or plate.
Yamaha has mastered the Art of Seasoning Wood.
Years of proprietary research and design has created a scientific wood drying process that maintains the integrity, shape, strength and resonance for decades.
All of Yamaha’s woods go through the Kitami Mill in Hokkaido, Japan,
The height of an upright or the depth of a grand piano and the metal harp inside determines the scaling of the instrument.
Some upright models have more cooper wound bass strings with the hammer hitting one to two stings at once, other’s have more tri chord steel strings which the single hammer strikes 3 individual strings at once.
Due to the complexity of the scaling and the differences in sting height and width Yamaha produces a unique set of hammers for each individual piano model.
This customized approach allows for greater control of tone, response and durability for a life time of enjoyment from your instrument.
In Yamaha’s factory in Kakegawa, Japan, coil winders wind pure cooper over a steel string core to create a custom bass strings for every Yamaha piano.
A piano string is not like other instruments in which the musician will have to switch out and can choose from different sizes or gauges.
Each string is made to exacting specializations with variances in size, tension and wounding in order to produce the desired tone and timbre.
