Introduction
When you go to see a movie or a play, you watch it for the visuals- for the dialogue and the action. Hardly ever does anyone say theyâre going to the theatre to listen to the background music. However, while it may not seem important when there are things exploding or couples publicly professing their undying love for each other, that âbackground musicâ you so quickly dismissed, is often what makes your favorite scene so powerful and heart wrenching.
Even at home, television commercials use music that draws in the audience in order to keep them from changing the channel. The SPCA, for example, is one of the most well known for producing tear-jerking commercials. On top of the montage of images showing adorable, albeit emaciated or scarred, animals, and the voice-over recounting the horror stories the poor pets had survived, what really breaks you down in the end is Sarah McLachlan mournfully singing âAngelâ in the background.
 "But even without the music, the commercial would still be extraordinarily depressing; Batman racing the Batmobile up a dark and winding road on a windy night would still be daunting and awesome," you cry.
Except, it really wouldnât. Imagine watching Jaws without the ever-increasing suspense created by the quickening tempo of the short, low tones and the higher and slightly discordant notes that make your heart race. There would be no tension to go with the anticipation for the oversized beast that would sooner rather than later come bursting from the water to attack innocent swimmers. In fact, you might just mistake the movie for a documentary about the increase of shark attacks at a certain beach.
 "I see," you say slowly. "I guess this music thing really is more important than Iâd originally thought. But do all productions use the same techniques to create tension or express the overwhelming stress of a student trying to finish an essay the night before itâs due?" Why yes, the styles and techniques are all incredibly similar in their most basic forms. While the keys and rhythms vary drastically from piece to piece, and from one production to another, there is one thing that always remains constant.
Music is used to inspire emotional responses, whether positive or negative; and on average, there are certain techniques and styles that donât differ as drastically between pieces of music, and never fail to make a crowd scream, laugh, or cry.
 Letâs see some examples, you say? Well todayâs your lucky day. I have two pieces that are perfect for the comparison.
