Introduction- Backround Info and Hypothesis

You know whenever you hear your favorite song; you just get in a better mood? Well have you ever wondered if our body responds to the music? Do we physically react to a song we like? I wanted to find out.

All scientists agree that music embeds itself deep in our brains, starting with the ears and sending out electrical signals that create reactions in the brain that we haven’t quite figured out. Music hits our emotions, memories, and learning. Music psychologically gives us an outlet for our emotions and almost a rebellion against our classical origins at times. Music and brain activity have puzzled scientists for years but very little experimenting has followed. Playing Mozart while infants sleep seems to improve mental and emotional progress is a start but we really can’t prove it’s the music. Some doctors have prescribed music therapy to those with disorders involving over active mental or physical functions that seem to result in a more calm sense of being. Once again, it is very hard to prove.

Some things we can prove while listening to music is a change in physical reactions in pulse and GSR. GSR is your galvanic skin response which is more simply, a reading measuring how active your nerves are- calmed or hyped up. By using two pieces of equipment, these two changes can be found easily.

My hypothesis if that if I have people hooked up to a pulse and GSR reader while music is playing, then I will find a physical response to the song they like the most (a calming or a burst of energy).
