The Casio Privia PX-770 packs a true grand piano experience into a slim, modern design. Experience authentic piano playability, thanks to 88 full-size scaled hammer action keys with simulated ebony and ivory textures. Casio's proprietary AiR processing provides piano sounds that are as realistic as the PX-770's feel. In addition to its magical stereo grand piano sound, this digital piano has a total of 19 additional tones onboard to add expressiveness to your performances. You also get 60 built-in songs to play along with. And Casio's Duet Mode splits the piano's keys into two identical ranges, allowing a teacher and a student to play the same notes simultaneously — perfect for piano lessons. The Privia PX-770 also includes an elegant cabinet with a sliding key cover, music stand, and three-pedal board.
