In 9th grade, students have been learning about advances during the Progressive Movement. They also listened to the piano music of Scott Joplin that captured the "Ragtime" era. The music was catchy and interesting, and many students had heard it before. The music of Scott Joplin is featured in a famous film from the 1970's--THE STING.
Learning to play the piano and piano lessons were considered a mark of class during this era. To have your student in piano lessons meant that the family had enough money to spare....and a piano in their house. A piano was considered an equalizer, just as a nice car is considered that today. For many, piano playing ability meant that they were enjoying the popular music of the day.
There are some wonderful ragtime tunes that one can listen to on youtube. There are also simple versions and more complicated versions of Scott Joplin's music. His music represented an emerging middle class that had access to pianos and victrolas (early record playings).
