Introducing two new limited‑edition colors-Calm Blue and Mellow Beige-for the Privia PX‑S1100. The PX-S1100 is well known for its slim profile, authentic keyboard touch and rich expression. Based on the concept of “CALM & MELLOW” (moments of tranquility and ease), these special new color variations make it even easier to incorporate the piano as part of a routine that soothes the mind.
Layered notes at my own pace, guiding my heart into a centered flow.
Offers high‑quality sound and touch, all in the world’s most compact body.*
The keyboard mechanism, speakers and other components have been miniaturized as far as possible while still delivering the highest performance. Crucial to the keyboard's small size is Casio's proprietary high-density technology, featuring a space-saving internal structure with the circuit board mounted vertically. These innovations and others have made possible the world's slimmest* digital piano in terms of depth – allowing for extremely flexible placement.

The following is from our interview with pianist Hayato Sumino (Cateen):
“While the Privia PX‑S1100 delivers beautiful tone, its natural touch really stands out. When you play you can express everything from delicate pianissimo to powerful fortissimo—and truly feel the joy of producing a great sound, much like playing a grand piano.”

DESIGN
A special piano for a special space. The slim size and simple, minimalist design have been crafted to match a range of room sizes and interiors.
- Simple, minimalist design aesthetic matches well with any interior style.
- The world’s slimmest body housing a full-size weighted keyboard with a front-to-back depth of just 232 mm* allows greater flexibility in placement. *In terms of depth among other digital pianos with 88 hammer-action keys and built-in speakers, according to Casio’s survey as of July 2025.
- Flat, high-gloss-finish top panel with touch-sensitive controls.
- The soft and muted color palettes of these limited-editions perfectly reflect the theme of “CALM & MELLOW” as well as current trends in interior design.
- Along with the limited-edition colors, the current Black, White, and Red options are also available to suit your style.
SOUND & PLAYABILITY
Privia faithfully delivers the sound and playability of a grand piano. Experience the expressive touch, from the low notes all the way through to the high, and lose yourself in your playing.
Sound Source
- Multi-Dimensional Morphing AiR Sound Source produces a wide range of exceptionally detailed and playable tones, including grand piano tones that include the rich resonances of the acoustic instrument.
- The piano tone subtly changes over time and with every nuance of the player’s style, from the softest of touches to powerful, spirited playing.
- The overtones generated by the piano strings for each of the 88 keys—and the resulting complex body resonances—are faithfully produced to create a beautifully rich and vivid piano tone.
Sound System
- Built-in speaker system delivers well-balanced sound with depth and weight in the low end and a sparkling high end with a vivid sense of presence.
- Strengthened speaker diaphragm creates shimmering the high frequencies, while the reinforced internal structure keeps the low frequencies tight yet powerful.
- The Hall Simulator/Reverb function recreates the acoustic properties of concert halls and other performance spaces producing a realistic sense of presence. Create your own space with your preferred acoustic settings.
Tones
- It’s equipped with 18 built‑in tones that covers a wide range of genres from pop to jazz. This includes an authentic concert grand piano, electric pianos, organs, as well as strings and bass.
Keyboard
- Features the “Smart Scaled Hammer Action Keyboard” that combines a mechanical hammer action with digital control that delivers nuanced touch and expressive performance across dynamic ranges and registers.
- The white keys feature an ivory‑style textured finish, whereas the black keys have an ebony‑style texture that creates a premium feel that’s comfortable even during extended periods of play.
- The tone isn't affected just by how you press the keys; how quickly you release them also influences the nuance of both damping and resonance.
- 88-Key Digital Scaling technology means that volume is individually controlled for each key in response to how hard it is played, with the touch weight varying along the length of the keyboard, like a grand piano.
- The hammer response adjusts the timing of the production of sound according to both register and playing style, which provides the sensation of playing a grand piano.
- The key‑off response allows for fine control of either legato or staccato touch articulation, so you can tailor how notes connect or detach for precise expression.
Pedals
- Essential for piano performance, the supplied SP-3 damper pedal can be connected to the PEDAL UNIT jack. For greater expressive control, the SP-34 three-pedal unit (sold separately) with a continuously variable damper pedal, can be connected.
EXPERIENCE
Expand your musical experience. The Privia offers possibilities beyond just playing the piano to let you enjoy music to the fullest.

- Part on/off function allows you to mute the right- or left-hand part of song data saved in the user area of the digital piano or USB flash drive. Great for practicing each part separately. (Note that the effectiveness of this feature depends on the song data.)
- Two headphone jacks allow for up to two pairs of headphones to be connected for private listening.
Audio Recorder
