Yamaha Arius YDP-S55B Digital Home Piano (Black Walnut)

The Yamaha Arius YDP-S55B Digital Home Piano gives you a luxuriously expressive playing feel with the GH3 keyboard. It includes ear-friendly functions and compatibility with Yamaha’s Smart Pianist app. The lid becomes a flat tabletop when closed.

Enjoyment that Stays with You

The luxurious tone and expressive ease of playing stay true to the basics of a real piano. It almost plays itself, releasing the sound and music you have within. Start your day with music and a huge smile on your face, the ARIUS piano makes you want to play more and more.

Sound Sampled from the Acclaimed Yamaha CFX Concert Grand Piano

The YDP-S55 models all feature a piano Voice sampled from Yamaha’s flagship CFX concert grand piano, a renowned piano that delivers sparkling highs and a powerful resonant bass combined in a superbly expressive sound. The YDP-S55 has the same detailed sound from the lower keys to the higher keys full of clarity and rich in colorful harmonic content. It gives you extraordinary expressive power and nuance that authentically responds to your daily practice as well as your most emotion-filled performances.

Authentic Acoustic Piano

With an 88-key piano action, the GH3 (Graded Hammer 3) keyboard reproduces the touch of an acoustic piano, from a naturally heavy feel in the lower key to a lighter touch in the upper octaves. The GH3 keyboard provides a grand piano-style response and feels, allowing rapid note repetition and authentic expressive control. Moreover, there’s a half-damper feature that authentically replicates the damper action on a grand piano, providing rich expressive variation.

Harmonic Resonance Like that of a Grand Piano

One of the allures of the grand piano is the sympathetic resonance created by the vibration of the entire instrument. The YDP-S55 elaborately reproduces this rich sympathetic resonance through a ground-breaking technology called Virtual Resonance Modeling Lite (VRM Lite). The VRM Lite creates a richly varied sound by simulating the complex sympathetic tones created when the vibrations of the strings are propagated to the soundboard and other strings, corresponding to the timing and intensity of key playing and pedaling.

Rich Variety of Built-In Songs

Naturally, the YDP-S55 has an authentic grand piano sound, but it also features various other built-in instrument sounds, for a total of 10 Voices including electric piano, organ, vibraphone, and strings. The YDP-S55 also has 353 built-in songs, including 50 famous classical songs, and 303 comprehensive practice exercises from famous methods, such as Beyer, Burgmüller, Czerny, and Hanon. The instrument is also compatible with Yamaha's free Smart Pianist app, simply download the app to your smart device and connect it to the instrument. With the Smart Pianist app, you can easily operate the various Voice functions of the instrument and use it to call up scores of the built-in songs. It also features a comprehensive Piano Room function for changing the tonal quality and resonance settings of the piano sound.

Features for Greater Listening Comfort

The YDP-S55 employs new technology that corrects the sound balance optimally according to the volume you set giving you an exceptionally natural sound that’s easy to listen to and is gentle on the ears, even when playing for a long time. It also has a Stereophonic Optimizer effect that lets you enjoy the natural, spacious sound you experience sitting in front of an acoustic grand piano, even when wearing headphones.

Slim and Stylish Design

The piano cabinet has a slim depth that lets you neatly install it in any room, and makes for a chic, stylish design that effortlessly enhances your living space. Moreover, closing the keyboard lid gives the instrument a flat, unassuming look.

Limiting the Maximum Volume

A new Volume Limiter function lets you set a fixed maximum volume level, to protect your hearing from loud sound over the speakers or headphones.

Record and Play Back Your Performances

The YDP-S55 has powerful tools that let you record and check your performances, or record a part with just one hand and practice the other part while listening along to the first. Moreover, you can record two parts separately, for example, the left- and right-hand parts, or record two Voices in succession to make a complete song and arrangement.

Play Along with a Partner

This effectively makes the instrument two keyboards in one, letting two players play the same piano sound and octave range side-by-side. This is especially useful when learning with a partner, letting you learn and practice parts together.
