Around the time of the Great Gatsby, the types of music that were popular began to change dramatically!  Jazz, Blues, and Swing music suddenly became popular and along with them came scores of new artists, each with their own signature toe-tapping or heart-warming tunes. 
Jazz became popular in the 1920s because WWI had just ended, and people were finally ready to enjoy themselves again!  Some particularly famous Jazz musicians, such as "King" Oliver, composed songs that are still played often today, such as "Don't You Think I Love You?"

The first Blues song ever recorded came out in the 1920s.  "Crazy Blues", a song by well-known artist Mamie Smith, became a national sensation.

Just as jazz and blues songs were for listening, swing music was a type of jazz made just for dancing!  As dancing grew to be a more popular pastime, so did swing music.  A hugely popular swing dance was the Charleston!
