Information from Young Chang

Spruce soundboards with the highest sound-transmission coefficient
For soundboards, Young Chang uses A-class northern spruce, which provides
an excellent sound-transmission coefficient.
Young Chang’s ingenious soundboard design includes a low-note portion shaped like a round
speaker with creases, optimizing the efficiency of vibration and effect of
resonance and creating a deep, rich tone.

Precise action that expresses the pianist's emotion more delicately
The three factors of beautiful sound in a piano - volume, tone and quality - depend on the precise
action of the sound-producing mechanism of a piano. The action of a Young Chang piano,
consists of 4,500 parts, each manufactured with an error tolerance of 5/100mm, and made of
hard maple to resist deformation from excessive use.

A keyboard that conveys the soul of the pianist
Young Chang keyboards are made of wood with lower specific gravity but higher elasticity, giving
the pianist a softer yet firm sense of touch.

Hammers conveying the dynamic expression of the pianist
Hammers are adjusted to strike the strings in less than 1/250 of a second. They are constructed
with maple, walnut or mahogany and elastic hammer felt, providing a sensitive, dynamic response
to the expression of the pianist.

Pin blocks made of 17-layer laminated panel to raise bearing power
The continuity of tone is emphasized when a piano is located in a concert hall or school
auditorium. To ensure the bearing stress of tuning pins and maintain tuning stability, Young
Chang pin blocks are made of 17-layer hard-maple laminated panel
with layers glued at right angles.

Frames cast through the V-Process construction method
According to acoustic theory, piano frames must bear up to 20 tons of string tension. The frame,
which also plays a crucial role in the alignment of strings, is produced through the V-Process, an
electrical vacuum-casting method, in the Young Chang foundry.

Rims optimizing soundboard resonance
Round rims at the low-note portions prevent sound diffusion and
optimize the resonance of the soundboard.
