Simple and sophisticated design that invites you to play.

A great-sounding piano must look good too.

Each finish has been carefully selected and meticulously manufactured, so you can choose a piano that truly looks at home in your living room. Also, the cabinet is designed to deliver the best possible sound, regardless of where the piano is situated. Available in polished ebony, charcoal, dark rosewood, light oak and white.

Express yourself with the responsive PHA-50 keyboard.

When it comes to the wish list for your new piano, playing ‘feel’ should be a priority. Whether building basic skills or expressing yourself in a demanding performance, the HP704 ‘s responsive PHA-50 keyboard reacts to your touch—putting you in control and keeping you inspired. You’ll also appreciate the blend of artisan tradition and cutting-edge technology—sleek wooden sides give each white key a familiar feel, while the durable inner frame ensures maintenance-free reliability over years of daily playing.

Dynamic sound from powerful four-speaker system.

A great sound makes you play better. The HP704’s SuperNATURAL technology captures the essence of an acoustic piano in every note. And as you play, your performance comes to life through an advanced four-speaker Acoustic Projection System that delivers sparkling highs, warm lows, and everything in-between. The four speakers are configured as two pairs inside the instrument, and each pair is optimized to deliver superior sound reproduction across the piano’s vast dynamic range. Whether you’re playing or streaming music, you’ll hear every note in immersive, crystal-clear sound.
