Is the Piano a Percussion or Stringed Instrument?

Is the piano a percussion or stringed instrument?

Hey guys!

My friends and I were having a conversation the other day with our English and Literature teacher. My friends and I all play the piano so he wanted to ask us if the piano a percussion or stringed instrument.
My friends and I say percussion but here are the arguments for both sides:

Strings:
-It has strings in it hence the name strings
-These strings are finely tuned for a specific note as in any string instrument
- Here is an example:
When  you are playing the violin or guitar, you always have to tune it before you play.

Percussion:
- In a stringed instrument, you are always touching the strings to change the note. In a percussion, the note for that particular part of the instrument always is the same so you need multiple of whatever you are using to create a variety of notes.
- Here is an example:
When playing the drums, you have a drum set. Why? Because each particular drum can only make one sound, so you need multiple drums to create somethings that actually sounds good.
In every stringed instrument you touch the actual string to change the notes. Like in the violin, you are pressing on the strings and moving your fingers while you play with the bow. Also, in guitar, you are pressing the strings again to change the tune while you strum.


Thanks for reading! Please comment what you think and your arguments on the bottom!
