For something to be a pseudoscience it has to purport to be to a science. Homeopathic medicine purports to be a science but doesn't have scientific backing ergo it is a pseudoscience. Music, art, and history don't purport to be a science so, by definition, they cannot be a pseudoscience. This is a false dichotomy.
