Some of the most timeless hits have been recorded on a Yamaha C Series piano. Now this legendary piano has been refined with many of the innovations from our flagship CF. The back posts, soundboard, ribs, strings and hammers have been redesigned for a more delicate attack, rich harmonics, infinite colors and a beautiful resonance capable of long sustained pianissimo tones and nuanced, expressive fortissimo. In the process of refining a legend, the CX has redefined what a grand piano could be.
