Charms

If Transfiguration involves changing the properties of an object, Rowling has described Charms as a type of magic spell concerned with giving an object new and unexpected properties. Charms classes are described as notoriously noisy and chaotic, as the lessons are largely practical. Many of the exposition sequences in the books are set in Charms classes, which are on the second floor of Hogwarts. Charms is taught throughout Harry's time at Hogwarts by Filius Flitwick.
