The spectrum of the arts is the idea that the term art can be split up into several different sections. When Monaco says this, he is trying to imply that you can be an artist at one thing but not another (hence the use of the word spectrum.) For example, you can be a musical artist. The seven different arts he originally mentioned were History, Poetry, Comedy, Tragedy, Music, Dance, and Astronomy although these have drastically changed over time.  

The art of history has contributed to both modem science and religious rituals.  art of comedy was plays such as Hamlet or the merchant of Venice but is now seen through stand up or films such as dumb and dumber. The art of tragedy is similar in the 1600s it was plays such as Macbeth and Romeo and Juliet but is now seen in films such as titanic. The art of poetry has not changed much with people still reciting poems such as In Flanders Fields. On the other hand, the art of music has completely changed from Mozart to Rap and drum and bass. The art of dance remains the same however more genres have evolved from original dance such as Contemporary dance or even breakdancing. Finally the Art of astronomy has been forgotten about and replaced    

After watching the joker, I thought the film was a solid 8/10. I think that the story of a clown who goes on a downwards spiral getting more and more insane is kind of cool. The fact he kills Murray on the show really shows he has nothing to lose. I found the film kind of dark however that does portray the mood of the film very well. One of my favourite most memorable scenes is when the joker is running from the policemen on the subway train. I liked this scene as found it was shot really well and when the policemen get mobbed it is really cool seeing him walk away like nothing happened.
