Product Description

A Truly Grand Experience.

With its beautiful form evoking impression of dignity and stability and its overall height equivalent to a grand piano’s, the GP-400BK gives pianists the sensation and visual perspective of performing on a grand piano. Careful attention to detail, such as installation of an appropriately wide music stand and construction with thick legs and other components, adds further luster to its appeal.

Perfect combination of innovation and tradition

The GP-400 is the latest - and the most elegant - model in the CELVIANO Grand Hybrid lineup. Like the GP-300 and the GP-500 comes the GP-400 with the three historically popular grand piano sounds and the keyboard is made of the same high-quality Austrian spruce as keyboards in C. Bechstein grand pianos. The new look and haptic makes you feel like playing an ordinary piano.

In development of CELVIANO GRAND HYBRID, Casio insisted on perfection of sound and touch. Developed in collaboration with C. Bechstein - together, they bring the perfect combination of innovation and tradition.


Our hearing goes beyond simply left and right, and we can detect the origin of sound from all directions. Using an exclusive six-speaker amplification system, CELVIANO Grand Hybrid recreates the three-dimensional soundfield that an acoustic grand piano generates.


CELVIANO Grand Hybrid reproduces even subtle nuances of the world’s most respected pianos. Three pianos that originate in Berlin, Hamburg and Vienna were chosen for this project. Casio has painstakingly researched and analysed the unique characteristics of each piano. CELVIANO Grand Hybrid delivers brilliant sound of these pianos reproduced with Casio’s advanced technology. It will provide the experience of owning three of the finest pianos on earth.


CELVIANO Grand Hybrid delivers authenticity from the first touch. The revolutionary new Natural Grand Hammer Action keyboard is made with full-length, wooden keys. Its new mechanism incorporates real hammers that follow the same path of motion as in a concert grand piano.

When the lid is lifted, you can see the hammers in motion through a clear panel as you play. Going beyond a standard acoustic mechanism, this new action allows faster note repetition than any acoustic, while maintaining a true piano touch.
