You said that the white and black things on the piano keyboard are called pitches. I was taught that they are called keys but after meeting you I was convinced of yours. I was wondering,if they are not called keys why is the piano board called "keyboard"

I'm not a vocal instructor but I think I can help here! The white and black things on a piano are called keys and that's the physical object you press when playing it (and why it's called a keyboard). However, when you press a specific key, the piano plays a note at a specific pitch, with pitch here meaning a specific level of how high or low a note is. So the middle C key plays a note at the pitch middle C. I hope that explanation made sense. :)

There is also the idea of a musical key, which is a way to describe how we group musical notes according to what note they're based on, but that's a different concept! Pianos have physical keys on them that represent and play pitches and that should be all you need to know for your question

Rosella is right! Thank you for jumping in, Rosella! 

Okay so Rosella if I got you right the black and white keys on the piano are physical keys and there are musical keys
