Another key to the order in music is the music being the same and different. The brain works by looking at different pieces of information and deciding if they are different or the same. This is done in music of the baroque and classical periods by playing a theme and then repeating or changing the theme. The repetition is only done once. More than one repetition causes the music to become displeasing, and also causes a person to either enter a state of sub-conscious thinking or a state of anger. Dr. Ballam goes on to say that, "The human mind shuts down after three or four repetitions of a rhythm, or a melody, or a harmonic progression." Furthermore, excessive repetition causes people to release control of their thoughts. Rhythmic repetition is used by people who are trying to push certain ethics in their music.
An Australian physician and psychiatrist, Dr. John Diamond, found a direct link between muscle strength/weakness and music. He discovered that all of the muscles in the entire body go weak when subjected to the "stopped anapestic beat" of music from hard rock musicians, including Led Zeppelin, Alice Cooper, Queen, The Doors, Janis Joplin, Bachman - Turner Overdrive, and The Band.
Dr. Diamond found another effect of the anapestic beat. He called it a "switching" of the brain. Dr. Diamond said this switching occurs when the actual symmetry between both of the cerebral hemispheres is destroyed causing alarm in the body along with lessened work performance, learning and behavior problems in children, and a "general malaise in adults." In addition to harmful, irregular beats in rock music, shrill frequencies prove to also be harmful to the body. Bob Larson, a Christian minister and former rock musician, remembers that in the 70's teens would bring raw eggs to a rock concert and put them on the front of the stage. The eggs would be hard boiled by the music before the end of the concert and could be eaten. Dr. Earl W. Flosdorf and Dr. Leslie A. Chambers showed that proteins in a liquid medium were coagulated when subjected to piercing high-pitched sounds.
Certain types of music or more specifically, violent lyrics, are believed to have a negative impact on adolescents. Studies have shown that the violent lyrics in rock music have contributed to youth violence. Eighteen-year-old Phillip Morton hung himself while listening to songs “Goodbye Cruel World" and "Waiting for the Worms," from Pink Floyd play in the background. (Watkins, 4) With the high strung guitar, vibrating drums and destructive themes playing, rock music can increase the mood of the individual listening to it and promote anti-social behaviors.
n terms of hip-hop music, sexually explicit lyrics and mounds of profanity exuberate through certain hip-hop songs. This can have a negative impact on the thoughts and feelings of adolescents. Some theorize that listening to it for long periods of time or in solitude by placing headphones on, this music can further damage the psyche of these young, impressionable minds further desensitizing their attitude towards sex.
