Added to the GH3 keyboard are synthetic ivory keytops, which provide a pleasant touch even during long performances. In addition to the RGE Sound Engine, a piano sound source reflecting Yamaha's precise attention to detail, the CLP-440 even achieves the resonance of acoustic piano strings, subtle changes of sound when your fingers rise from the keys and mellow reverberations the instant the damper pedal is pressed. Grand piano-like, rich, expressive, sound will vividly resonate in perfect harmony with your performance. There are also multiple colour variations you can choose from to suit your taste and the decor of your room.
