IntroductionAimsI because the music would be seen as

IntroductionAimsI chose this experiment because I am very interested in music. Music has helped me get through most of my life, being listening to it while studying or getting over a breakup. Music can define your emotion, whether you are happy, sad, angry, etc. Music is something that is universally known, and can take in multiple forms. Every person has their own unique taste in music, and certain types for specific situations. I want to see if those preferences affect your body, more particularly heart rate. BackgroundIn this experiment I will be measuring heart rate. The heart rate of a person is the speed of their heartbeat. This is found by counting the amount of contractions the heart has every sixty seconds. There is an estimate heart rate range for people however it changes as age increases. An average resting heart rate ranges from 60-100 beats per minute. Different factors that can change heart rate can be eating, exercise, gender, body temperature, etc. The heart compensates these changes by contracting at a faster pace. Different genres of music can alter factors in heart rate, which will then change the heart rate. Factors can include epinephrine levels, the medulla, or oxygen, pH levels, or blood pressure. High tempo or low tempo music depending on the individual can spark threat, memories, or opportunities, which can affect one’s heart rate. I expect that loud music or high tempo beats would cause an increase in heart rate. I expect this because the music would be seen as a threat, which would increase epinephrine levels, which then increases heart rate. I expect calm, peaceful music would lower or steady the heartbeat because there is no threat. Through this research, I hope to find a way for people with chronic pains in the heart or heart problems in general to reduce their pain. This matters because it can help everyday people live a better life. Hopefully it can alter their perspective on their pains. Perhaps listening to peaceful music will help patients feel less pain since it possibly will result in a lower heart rate.  High tempo or loud music might result in a high heart rate, which can tie to stress and anxiety.

I will reference this when I conduct my experiment.
