Why is a piano chordophone?

A piano is a chordophone because it produces sound by the vibration of strings. The strings are stretched between two fixed points, and when they are plucked or struck, they vibrate and produce sound. The pitch of the sound depends on the length and tension of the string, and the timbre of the sound depends on the material of the string and the shape of the instrument's body.

Here are some specific details about how a piano works:

* The strings are made of steel, and they are stretched between a metal frame at one end and a wooden soundboard at the other end.

* The strings are plucked by hammers that are attached to keys. When a key is pressed, a hammer strikes the corresponding string, causing it to vibrate.

* The vibrations of the strings are amplified by the soundboard, which is made of a thin piece of wood. The soundboard vibrates in sympathy with the strings, and this vibration causes the air inside the piano to vibrate.

* The vibrating air produces sound waves, which travel through the air and can be heard by listeners.

The piano is a versatile instrument that can be used to produce a wide variety of sounds. It is often used in classical music, jazz, and popular music.
