The Science of Fit
Advanced Ergonomic Geometry
Most manufacturers hide their exact key dimensions. We publish ours openly because we engineered them down to the micrometer specifically for your hands.
The "Forgiveness Funnel" vs. The "Elevator Shaft"
Take a close look at a standard acoustic piano. The black keys aren't straight blocks; they are shaped like pyramids with a heavy outward slope (a 6.48° draft angle) towards the base.
This traditional shape acts as a "forgiveness funnel." When small-handed pianists stretch to reach large chords, their fingers naturally splay out and flatten, striking the keys at a severe diagonal angle. The heavy slant acts as a funnel to catch sloppy, angled finger strikes. But this design severely chokes the physical space available for your fingers at the bottom of the keybed. The slanted key is essentially a band-aid for an ergonomic problem caused by the piano itself.
David Steinbuhler, creator of the DS Standard, engineered a brilliant solution for the narrower sizes: he practically eliminated the taper. On the DS5.5 and DS6.0, the black keys feature nearly vertical walls. The DS5.5 features a virtually invisible 0.83° slope, acting like an "elevator shaft."
The Biomechanical Paradox
Because the octave is perfectly matched to your hand, you no longer have to stretch. Your hands stay relaxed in a proper "dome" shape, allowing your fingers to descend perfectly vertically. You don't need a forgiving funnel anymore!
By standing the walls up straight, we preserve an incredibly spacious playing gap between the black keys.
The Result: Despite being a much smaller keyboard overall, the physical gap where your fingers depress the keys on our narrower sizes is actually wider than the gap on a full-sized 6.5" acoustic piano!

Black Key Dimensions
Engineered for perfect finger clearance utilizing near-vertical sidewalls.
* Key draft angle and gaps are calculated based on an estimated 0.52 to 0.57 inch exposed black key height.
Chassis & Footprint
The exterior dimensions of the instrument.
* Note: Both the DreamPlay One and the upcoming DreamPlay One Pro utilize the exact same exterior chassis structure, providing a sleek, unified footprint. The Pro model includes upgraded internal components such as larger 40W speakers and a Triple-Sensor action.
