ARIUS YDP-S31

The Graded Hammer Standard (GHS) keyboard of the YDP-S31 provides exceptionally natural key touch virtually replicating that of an actual grand piano.

Built-in AWM stereo sampled instrument Voices faithfully reproduce their complete range
— from the soft, dark lows to the glistening, bright highs.

The damper pedal includes an authentic Half Damper effect,
giving you nuanced expressive control over the sustained sound…
far more realistic than a simple on/off footswitch.

Built-in song recorder and metronome make the instruments ideal for piano lessons, practicing, or even as a scratch pad for you next masterpiece.

50 specially selected piano songs of standard piano repertoire are built into each ARIUS, either for your listening enjoyment, or as a rehearsal tool while playing out of the included 50 Greats for the Piano book.

Drawing on over a hundred years of experience and craftsmanship in making world class acoustic pianos, Yamaha introduces the ARIUS series. All of these instruments provide exceptionally natural, grand piano-like touch, with realistic weight gradations—heavy in the lower end and light in the upper. The YDP-140 and YDP-S31 have the Graded Hammer Standard keyboard with realistic matte black finish key tops. The premium Graded Hammer action of the YDP-160 provides even greater expressive control, including repeated playing of the same note with perfect articulation. In this way, the Graded Hammer keyboard suits skill levels from Chopsticks to Chopin Etudes and everything in between.

The ARIUS series utilize Yamaha's sophisticated AWM (Advanced Wave Memory) Stereo Sampling for the instrumental voices—faithfully reproducing all of the dynamic details and sonic nuances of the original. Taken at different 3 levels of soft, medium and loud each key is comprised of multiple stereo recordings of an actual grand piano. This provides subtle differences in volume and timbre depending on how you play the keys, and gives you full expressive control over the sound.
