So, when you play the piano or the keyboard, you’re pressing down on these things that look like little boxes. Those are the keys!
Now, the key bed is the surface that all of the keys rest on, kind of like a big, flat board. Think of it like a bed that the keys lay on.
The key bed is really important because it needs to be very flat and level so that the keys all press down evenly. If the key bed was bumpy or wobbly, some keys might not work as well as others, and that would make it hard to play music.
So, when you see people playing the piano or the keyboard, just remember that the keys are laying on a special bed to keep them all working smoothly!
