As Hogwarts Charms Professor, Filius Flitwick was in charge of teaching his pupils everything from Cheering Charms to making objects fly - combining accurate incantation enunciation with the precise wand movements (like the ‘swish and flick’). As Head of Ravenclaw house Flitwick was an integral part of school life. Despite his diminutive size, Flitwick's magic was powerful, complex and instrumental in protecting Hogwarts from various external (and sometimes internal) dangers - he was even a once a duelling champion.
