Trivia
Why does a flute have a lip plate attached?

In fact, the lip plate was created so that a metal flute would have the same thickness as a wooden flute at this point. Theobald Boehm-the pioneer of the metal flute-proposed adding the lip plate in order to make the instrument easier to play.
The lip plate is a curved, oval-shaped metal plate, which is connected to the body of the flute by a component underneath it known as a riser.
