What are piano strings?

Piano strings are thin wires that vibrate to make music when you press the keys.

Imagine a rubber band stretched tightly between your fingers, when you pluck it, it twangs and makes a sound. Piano strings work in a similar way, but they're much thinner and made of strong metal. When you hit a key on the piano with a hammer inside, it strikes one of these strings, making them vibrate really fast.

Each string is attached to two ends, like a tight thread between two points. The more tightly stretched the string is, the higher the sound it makes, just like how a tight rubber band makes a sharper twang than a loose one.

Pianos have many strings, some are thick and make deep sounds (like the rumble of thunder), while others are thin and make high, bright sounds (like a bird singing). All of them work together to create the music you hear when you play the piano.
