Folk music is the music an ethnic community uses to identify itself. Nearly all of humanity shares folk music. Folk songs are communal compositions. They are expressions of the culture that produces them. A community helps support one another by learning, growing and celebrating the beauty surrounding as well as within.
Music offers inspiration.
Here is an experiment. Listen to music, pleasant to your taste, as often as possible for a month. Notice the difference in attitude toward life. If you do listen frequently, try a week without music and note the effect. Music expresses the central social values of nearly all societies.
