乡村音乐(country music)

　　today is a very happy day. i have just watched a rockˊnˊroll music. when it became popular in the late 1950s, accompanied by accompanied by a great variety of energetic dance styles.

　　the idea was to “ move to the music ” anyway you felt like moving. popular dance has become more and more free since that time. the music emphasized harmony and repeated melodies; the dancing , like the music, was smooth.
