Unit 4 MusicLesson 1 Music and BehaviorWhere did you go yesterday? Did you hear music at any of those places? There is a good chance that you did. Today most stores and restaurants play music. You might even hear music in an office or on a farm.Scientists believe that music affects the way people behave. According to some scientists, the sound of western classical music (Mozart and Bach) makes people feel richer. When a restaurant plays classical music, people spend more money on food and drinks. When the restaurant plays modern music, people spend less money. With no background music, people spend even less.Scientists also believe that loud, fast music makes people eat faster. People actually chew their food faster when the music gets faster. Some restaurants play fast music during their busy hours. This gets people to eat faster and leave quickly. Restaurants can make more money this way.Some scientists think that music makes you think and learn better. They say that music helps students to be more alert.

Unit 4 MusicLesson 3 Rock and RollRock and roll came from jazz and the blues during the 1950s. One of the first rock and roll songs was Bill Haley's "Rock Around the Clock. "One of the first very famous rock and roll singers was Elvis Presley. Others were Buddy Holly and Chuck Berry. Now almost every country has many rock and roll bands and singers. Sometimes performers call their music by different names, like "rap" or "punk. " They sing and play mixtures of rock and roll and talking or other sounds. Rap and punk both came from rock and roll, or rock music.Some fans who like rock music think that classical music is boring. Many fans play rock music very loudly.
