A piano will produce a sympathetic vibration when 1) a key is held down until the note dies away, leaving the string "open" and the damper raised and 2) a different key (for example a note an octave above or below the key you are holding down) is pressed and released. Still, sound will be heard from the first key because it was set in motion by the second note (they share overtones).
This is called sympathetic vibration or sympathetic resonance.
sympathetic vibration
Because It is the vibration of the strings inside the piano that produces the sound of the piano.
Pluck the string with your finger or with anything (like a pick or the hammer of a piano) and it will cause the string to vibrate at a frequency which is determined by the thickness of the string and the length of the string (which is a fixed length on a piano, but is determined by where you fret (push down on with your fingertip) the string on instruments like guitars and violins. The frequency of the vibration determines the note... since sound IS vibration.

Sympathetic vibration occurs when one object vibrates in response to the vibrations of another nearby object. In musical instruments, sympathetic vibration can enhance resonance by causing other parts of the instrument to vibrate along with the primary vibrating element, creating a richer and more sustained sound.

When the left pedal on a piano is pressed, it softens the sound by dampening the vibration of the strings.

Vibration
Sound
Because when you strike a key (press it down) the mechanism strikes a felt tipped hammer against the string to produce the note.A Piano can be considered as Percussion instrument because whenever you press down on a key, A little hammer on the inside hits a string causing the string inside the Piano to vibrate. The vibration of the strings are what causes it to produce the sound the piano makes. Furthermore, a piano can be classified as a Idiophone because the hammers that hit the strings are what causes the string to vibrate. Piano cannot only be classified as a Percussion Instrument but also a stringed instrument.
When the far left pedal on a piano is pressed, it softens the sound by dampening the vibration of the strings.
