Dream of the definition of "lyric"

 In a class we were supposed to write down a definition of "lyric." I was the professor but someone else was presenting in class and so this was an activity they had designed. I wrote "A poem meant to be set to music; a poem associated indirectly or vaguely associated with the tradition of poems to be set to music; any short poem."  We all read our definitions out loud. I don't remember what the other ones were.
