Step Into the Art of the Piano
Learning to express yourself musically is about more than proper technique—you also need to build a sense of musicality and develop a feeling for what you want to share with the world.
ARIUS pianos are more than just tools for practice—they are partners on a lifelong musical journey, allowing you to pour your full range of emotions into the keys, and discover your capacity to breathe life into music.
True Piano Expression
For over a century, Yamaha has crafted the pianos played on the world’s greatest stages. The ARIUS Series brings this heritage and technology into your home with instruments designed to offer beginning players and those returning to playing after a break the authentic feel and resonance of acoustic pianos.
For beginning players or those have just returned to playing the piano, it’s important to choose a instrument that possesses one of the key factors behind the expressive power capabilities of the piano—the ability to respond to your touch exactly as you intended.
Consistent Feel and Expressive Response for Superb Expressive Control
The YDP-166 offer pianists control over the delicate nuances of the instrument’s sound, allowing them to play the keys at different intensities and to different depths throughout the 10-mm stroke to suit the mood and desired dynamics of a piece.
The GrandTouch-E™ keyboard provides a real sense of responsiveness and complexity that changes with how it is played, much like a grand piano. The keys respond consistently, even when you play many notes at once.
Intuitive Pedaling for a More Nuanced Performance
Like the keys, the pedals are parts of the interface between the player and the piano. ARIUS pianos have a damper pedal, a soft pedal, and a sostenuto pedal, just like grand pianos. The pedals can be used to sustain sounds as well as add depth and create crispness, putting a broader array of expression at your feet.
The pedals are realistic-feeling and responsive, delivering a level of precision that allows you to play exactly what you imagine.
Bringing the Sound of a Concert Grand Piano into Your Home
The Yamaha CFX concert grand piano used for the sampling was tuned to perfection by a seasoned professional so that every note from the dazzling treble to the powerful bass could be recorded with care. Yamaha then meticulously adjusted each note to create a harmonious piano Voice. These thoughtful efforts resulted in a faithful simulation of colorful tone and dynamic nuance throughout all registers, and delivered a beautifully resonant sound.
Clearer Sound That Travels Farther
Over the decades, Yamaha has refined its digital technology through both research and development, studying the sound-producing mechanism of grand pianos and designing pro audio equipment and sound systems.
The knowledge derived from these efforts underpins the workings of ARIUS pianos, which appeal to both players and audiences with clear, resonant sound despite being compact digital pianos. The new diffuser grille makes treble notes even clearer, creating a pleasant, well balanced sound field that resonates throughout all registers.
Beautifully Simulated Depth of Resonance from Piano Strings
Grand pianos are known and loved for the resonant sound produced when the entire instrument vibrates.
As a long-time manufacturer of grand pianos, Yamaha is intimately familiar with how grand pianos resonate, and funneled its knowledge into the development of VRM Lite, which faithfully simulates the complex resonance of a grand piano when the vibrations of the strings belonging to the notes being played are transmitted to the other strings. The resonance depends on when the keys are played and how far down the pedals are depressed.
A Partner for Everyday Life
When your piano blends in at home, music becomes an integral part of everyday life.
ARIUS digital pianos feature refined designs and convenient features in compact units that are perfect for apartments, living rooms, and other spaces in the home.
Smart device connectivity along with recording functions and expressive Voices ensures that daily practice is more fun and effective, making music an indelible part of your everyday life.
Sophisticated Design That Blends in with Home Interiors
Deceptively simple design with curves incorporated throughout to create a graceful presence fitting for a piano. The YDP-166 have gently rounded corners and other safety features to make them safe for people of all ages.
The design combines safety with sophisticated beauty that blends in with home interiors, a hallmark of Yamaha digital pianos.
Helpful Features for Practicing and Performing
Yamaha has expended every effort to deliver a pleasant playing experience, even with headphones.
The sound balance is automatically adjusted to the volume, making the output pleasant at any level. ARIUS pianos also have a Stereophonic Optimizer that simulates the natural spread of sound as if you were sitting at an acoustic piano, rather than simply emitting a sound to be heard only in your ears, creating a more immersive playing experience.
The menu of preset songs includes pieces from the accompanying collection of sheet music, “50 Classical Masterpieces,” as well as 303 exercises from piano method books by Beyer, Burgmüller, Czerny, and Hanon.
Expanding the Fun of the Piano
Featuring a total of 10 Voices, including an authentic grand piano Voice as well as electric piano, pipe organ, vibraphone, and strings.
Try the Voices with any genre of music, or layer them on top of each other to enjoy playing in ways only possible on a digital piano.
