Scott Joplin was an African American composer and pianist of singular merit and influence. This article is the final entry in a three-part series considering the biographical, artistic, and cultural contexts of Joplin's life and work and their use in K-12 general music education. "Ragtime Spaces" focuses on cultural globalization and the modernist entertainment aesthetic which supported Joplin's work. Scott Joplin's creative and entrepreneurial activities embodied humanism, racial uplift, and craftsmanship at a time when society became increasingly racially segregated and dehumanized. The discussion is followed by suggested student activities written in accordance with National Association for Music Education's 2014 National Music Standards.
