Relating to what the previous tutors have stated but from the viewpoint of a musician, I would say that the ties between classical music and classical literature are the overall importance that society may place on a given work. Over time, works such as novels and pieces of music become a part of our canon; in other words, these works become the standard, showing credibility in their given fields. The "classical" definition can mean two things in music; either applying to the time period from the 1750s to around the 1820s, or it can mean the overarching genre of music, usually those involving the orchestra. For my explanations, I will refer to classical music as a whole, rather than the period. We consider Shakespeare's Romeo and Juliet a classic work because of its commentary on the tragedies of young love. Likewise, Beethoven's 5th Symphony is considered a classic work because it is used significantly in movies, TV shows, and other pieces of music, known especially for its main motif.
