Wikipedia defines The Arts as those areas of study, personal endeavour, and higher education (particularly at a post-secondary level) in fine art and humanities as opposed to the sciences, professions or callings. I use the term in a rather less formal sense. For a practical classification scheme have a look at the Open Directory Project category.
I have fairly broad interest in the Arts, covering Literature (Italo Calvino, Kurt Vonnegut), Music (Reggae, J. S. Bach), Cinema (Andrei Tarkovsky, Ridley Scott), as well as Dance, Theatre, Sculpture, Poetry etc. One of my favourite artists is the poet/singer/songwriter Aidan Andrew Dun, who also happens to be a friend.
