Would a native speaker say "They are great parts of art", if I am talking about music and dance? And if I am talking about one thing, for example, photography can I say "It's a great part of art"? Is it grammatically correct and natural?
Perhaps I should use "an art form" and "art forms" instead? Do native speakers prefer "art forms" and "an art form" instead of "a form of art" and "forms of art"? For example, "It's a beautiful art form." Not "It's a beautiful form of art." Or "They are beautiful art forms." Instead of "They are beautiful forms of art."
