Virtual Piano Tips: Keys, Sliders and Two Modes Tested

Key takeaways
- At the default size the keyboard shows 10 white keys across a 1280 px screen, 128 px per key.
- Dragging the right slider to the left doubled the key width to 256 px, so 5 keys fit.
- The left slider moved the keyboard sideways without changing the key width.
- Mode 2 has a red panel with an infinity button and three wave buttons; the pressed one turns pink.
The first virtual piano tip is to use the slider: in Keybloom ten white keys fit a 1280 pixel screen by default, and dragging the right slider to the left made each key twice as wide, 256 instead of 128 pixels. Keybloom is a music toy with two modes, so how the keys look and where they sit is most of what you can change.
How the toy works
Keybloom has a start screen with two bars, Mode 1 and Mode 2. After you pick one, a keyboard fills the screen below a bar of controls. There is no score and no timer. You click or tap the keys to play them.
What we measured
We opened Keybloom in a test browser at 1280 by 800 pixels, played with the controls in Mode 1 and read the key edges in the screenshots.
| What we did | Result |
|---|---|
| Default view | 10 white keys, 128 px each |
| Right slider dragged to the left | 5 white keys, 256 px each |
| Left slider dragged to the right | keys stayed 256 px; the keyboard moved sideways |
One run in one test browser; key widths measured from the vertical lines between the white keys.

The two modes
Mode 1 has a wooden-looking panel with a loop-style button and three numbered buttons, I, II and III. Mode 2 has a red panel with an infinity button and three buttons drawn with wave shapes. In Mode 2 we pressed each button in turn and the one we pressed lit up pink. Both modes have the two sliders in the bar.
4 tips that follow from the numbers
- Widen the keys first. The right slider doubled the key width from 128 to 256 pixels.
- Use the left slider to travel. It moves the keyboard sideways without changing key size.
- Try both panels. Mode 2 shows which button is active by turning it pink.
- Play with the mouse or a finger. We found no keyboard shortcuts.
Where to try it
