Piano frames must bear up to 20 tons of string tension. Frames cast through the V-Process construction method According to acoustic theory. Young Chang pin blocks are made of 17-layer hard-maple laminated panel with layers glued at right angles. To ensure the bearing stress of tuning pins and maintain tuning stability. 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. Walnut or mahogany and elastic hammer felt, providing a sensitive, dynamic response to the expression of the pianist. Hammers conveying the dynamic expression of the pianist Hammers are adjusted to strike the strings in less than 1/250 of a second. Giving the pianist a softer yet firm sense of touch. more keyboards are made of wood with lower specific gravity but higher elasticity. A keyboard that conveys the soul of the pianist Young Chang.
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. Tone and quality– depend on the precise action of the sound-producing mechanism of a piano. Precise action that expresses the pianist's emotion more delicately The three factors of beautiful sound in a piano– volume. 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. Young Chang uses A-class northern spruce, which provides an excellent sound-transmission coefficient. Spruce soundboards with the highest sound-transmission coefficient For soundboards.
