Have you ever seen a grown-up drumming on a weird-looking flat thing with sticks? That's called a practice pad, and it's a special tool for drummers to practice their beats and rhythms without making too much noise.
A practice pad is like a tiny drum that sits on a table or a stand. It's usually made of rubber or some other soft material, so it doesn't make as much noise as a real drum. Drummers use special sticks called drumsticks to tap on the practice pad in different ways to make different sounds.
The practice pad helps drummers get better at their drumming skills because they can practice their beats and rhythms without bothering other people in their neighborhood or house. It's like playing a video game that helps you get better at playing real drums!
So, if you ever see someone playing on a practice pad, don't worry, they're not crazy! They're just practicing their drumming skills without disturbing anyone else around them.
