AAA Spruce soundboard
Young Chang uses A-class northern spruce for soundboards, providing excellent sound-transmission coefficients.The soundboard, back posts, key frame and keyboard used in Young Chang Platinum Edition are made of carefully selected first-class materials.
A Bridge undercut that maximizes volume
The bridge must endure a string tension of up to 400 pounds as it delivers vibration to the soundboard. The Tenor Bridge gives more room to the soundboard for vibration by reducing adhesive surfaces, creating a rich, perfect tone.
An asymmetric tapered Soundboard
The thickness of the soundboard varies with an asymmetrical shape in the low-note portions that resembles the creases of a round speaker. As a result, the tone becomes richer and the overall sound more resonant, with a strong strike from a soft touch in the bass-note portion.
Sound ribs are crowned by machine asymmetrically
Specially designed sound ribs support the contact points of the bridge rather than the center of the soundboard. This design allows the piano to deliver fuller energy to the entire body while maintaining tone.
