The GP-400 is the Perfect Combination of Innovation and Tradition. From the moment your hands touch the keys, the Grand Hybrid delivers the authenticity your performance demands. The revolutionary new Natural Grand Hammer Action keyboard is made with full-length wooden concert grand piano keys, using the same materials and processes as the C. Bechstein concert grand pianos. A keypress sends a hammer along the same vertical path as a grand piano, with the same essential weighting and pivot points, resulting in a true and uncompromising piano touch.

For over 300 years, the piano has been embraced around the world as a vehicle for artistic expression. Its design has evolved through time, but the fundamental structure is still true to tradition.

Casio’s vision is to bring the piano experience to the next level by applying its technological expertise, and to create an instrument that would thrill the most demanding and traditional pianist.

Now, Casio begins a new chapter in the rich history of piano with the CELVIANO Grand Hybrid.

Authenticity Begins at the First Touch.

String/damper resonance, mechanical sounds, and other subtle nuances complete the experience of owning three of the finest pianos on Earth.

Grand Acoustic System

Our hearing goes beyond simply left and right, and we can detect the origin of sound in all directions. Using an exclusive six-speaker amplification system, the new Grand Acoustic System reproduces the three-dimensional sound field generated by an acoustic grand. The top speakers present sounds normally heard rising upwards, and the downward-facing speakers present sounds heard from below the soundboard. This simulation fills the room with rich, complex sound, reaching both the performer and the audience.
