• • • Really for artistic purposes? Its purpose seems to have been IAL, the "esthetic" side -- the musical version -- was partly practical (tone carries farther than words and is easier to pick out in a noisy environment) and partly either a bad joke or a misunderstanding of the claim that music is the universal language (which is clearly false even when rightly understood).
• loglangs, more recently called engelangs (Engineered languages), those devised according to some sort of objective principles; Lojban Description is one of these.
• auxlangs, those devised principally as IALs
