The importance of teenagers and their music is what helps teenagers get through their days. Every day hundreds of people with headphones walk through the corridors of schools. Teens listen to music every day, and most teens can't do without it. Music is what teenagers understand and it doesn't matter what type of music it is. What types of music do teenagers listen to? Some songs teens listen to are rap, rock, country, gospel, contemporary Christian and more. Do particular musical genres influence adolescents and their attitudes? “When adolescents use music as a mood modifier, it can be used to reinforce and perpetuate negative as well as positive emotions” (Allen, 2013). It is clear that music has an effect on adolescents' attitudes. The type of effect depends on the musical genre, with some genres causing positive effects and others negative effects. Music is everything in the lives of many teenagers. Music can speak to teenagers. There are many genres that teenagers can learn about and enjoy. Music is “the art of arranging tones in an ordered sequence so as to produce a unified and continuous composition” (Yoshimura, n.d.). Everyone has a different definition of music, so there really isn't a fixed definition. “There are many theories about when and where music originated. Many agree that music began before man even existed” (Estrella, n.d.). Music has been found since ancient times in the Middle East. "In ancient Israel, a thousand years before Christ, King David composed and sang hundreds of songs called Psalms" ("What is music and what is it"). There are hundreds of musical genres. Here are some important musical genres: rock, rap, gospel, country and classical. Gospel music is "a type of music based on the hymns and spirituals of the American South... at the heart of the paper..." .htmlRockMusic.mu (ed.). (n.d.). Rock'n'roll music.
