Privia PX Series

With a revolutionary piano sound, a stylish slimline design and a dynamic Sound Projection speaker system, the PX870 redefines what a compact digital piano can do.



Privia’s piano tones are sourced from recordings of world famous concert grand pianos. Casio applies advanced technologies to optimise pianists’ expressive capabilities by faithfully reproducing their individual keystroke characteristics and the changes in sound quality and volume produced by an acoustic piano with the passage of time.


The speaker system in the PX870 faces forward and back, which provides a remarkably similar sound character to a traditional upright piano.

A wide sound projection also makes the instrument suitable for classrooms, halls or other environments where an audience may be present.


Compatibility with the Casio Music Space for Piano app adds the ability to perform such operations as display of built-in music scores in PDF format and piano tone colour setting. When connected to a smartphone or tablet display, the app makes a variety of functions available for piano performances.
