Enjoyment that stays with you

Authentic acoustic piano touch

Weighted keys reproduce the responsive, controlled touch you’ve come to expect in a Yamaha acoustic piano.

The GHS keyboard provides a grand piano-style response and feel, allowing rapid note repetition and authentic expressive control.

Good virtual vibrations

Our innovative Virtual Resonance Modeling (VRM) recreates the resonance of the soundboard, rim and frame to emulate the natural feeling of an acoustic piano. Even while wearing headphones. Damper Resonance reproduces the broad, deep sound field of an acoustic piano. It also mirrors the tonal changes that result when a damper pedal on a grand piano is depressed. It includes sounds such as those emitted from the key bed and emulates the cumulative resonance that occurs when all of these sounds blend together.


3 pedals, unlimited expression

Half-damper pedal control. Soft (una corda), sostenuto and sustaining (damper) pedals provide the essential feeling and control reminiscent of that found on all acoustic pianos. The half-damper feature authentically replicates the damper action on a grand piano, providing rich expressive variation.

What are the differences between GHS keyboard, and GH3 keyboard?

GHS (Graded Hammer Standard) keyboard: Well suited for the beginner pianist and delivers the graded, weighted touch piano teachers recommend for building proper technique for playing acoustic pianos.

GH3 (Graded Hammer 3) keyboard: GH3 keyboard swings back faster, like high quality piano keys. GH3 keyboard allows the player to feel the weight of the key when depressed a second time, even when the player has not completely released the key after the first push of the key.

What is half-pedaling?

Half-pedaling is the function that enables you to change the amount of sustain by varying the degree to which the damper (sustain) pedal is applied. If the effect of the damper pedal causes the passage to be smeary, you can reduce the effect by decreasing the degree that the damper (sustain) pedal is depressed.

What is the maximum number of polyphony?

Polyphony is the total amount of notes that can be played by a musical instrument at one time. If the polyphony count is exceeded, the first notes played will begin dropping out.

A higher polyphony count enables you to enjoy playing more complex songs with both hands and extensive use of the damper pedal without interrupting the sound.

How much space is needed for placing the digital piano?

The width of the 88-key digital piano is over 1,350 mm [53-1/4″], and the depth of that is over 300 mm [11-13/16’’].

So, to play the digital piano with correct posture, at least 1,500 mm x 1,500 mm [59-1/16’’ x 59-1/16’’] is needed for placing the digital piano and the bench.

Can I disassemble the digital piano?

Almost all the digital pianos can be disassembled.

If you want to move the digital piano to another location but it is too big to move, you can disassemble it.

What type of headphones can I use?

Digital pianos (YDP) with the “standard stereo phone” connector allow you to connect headphones with the “standard stereo phone plug [6.3 mm] (1/4 inch)”.

Can I use alcohol or something to remove viruses?

Alcohol solutions (including alcohol-based disinfectants) and chlorine solutions can cause discoloration and deterioration of keys, exterior surfaces, panels, and so on. In addition, alcohol disinfectants for hands and fingers may also discolor or deteriorate the keys and control surfaces if alcohol remains on the hands.
