Korg C1 Air Digital Piano Design

The C1 Air features a simple design that carefully considers small spaces. Therefore, this makes the piano slightly different than the higher-end counterpart – the G1 Air digital piano.

The legs of the Korg C1 Air digital piano are structured in a manner you would only find on upright pianos, although they are a bit thinner. The good thing about these legs is that they project a sense of lightness and emphasized slimness.

Also, the horizontal support connecting the legs is positioned a bit higher, which creates a furniture-like impression that’s different than that you’ll find on a piano. The included closed lid in the C1 Air is flat and since the instrument is compact, it makes it bring out a look that appropriately harmonizes with your space and does not overpower it.

Additionally, the piano is designed in a variety of colors to choose from. Therefore, you have the option of selecting a color that matches your interior or the light in your room.


The Korg C1 Air digital piano features an 88-key keyboard with Real Weighted Hammer Action 3. This enables the keyboard to sound more like an acoustic piano and deliver an ideal playing experience.

The keyboard also offers a variety of layout options that make playing fun. By simply pressing one button, you can apply a bass sound to the lower register of the keyboard. You can play the piano with your right hand and bass with your left hand, which allows you to enjoy jazz performance styles.

There is also an option of layering two sounds together by simultaneously pressing two of the tone buttons. For instance, you can layer strings and piano to play with a combination of rich piano and orchestra.

The keyboard’s Partner Mode allows you to divide it into two identical sections on left and right, each with its own damper pedal. Therefore, the Partner Mode enables a teacher and student to play duets or simply copy and practice during lessons.
