Oddly enough most laypeople don't know about equal temperament, and most musicians learn in their training that it's not fundamental. In my earliest music lessons, I learned to tune my instrument, the cello, by perfect intervals. My teacher explained to me why the notes wouldn't match the piano exactly. Save for keyboards, most of the instruments in an orchestra don't have a well defined temperament.
