As a young adult, Ellington snuck into Washington's clubs and performance halls to catch ragtime performances by musicians such as James P. Johnson. At the age of fourteen, Ellington wrote his first composition "Soda Fountain Rags", also known as "Poodle Dog Rag". Washington's thriving black community inspired Ellington to become a composer. Additionally, through this community, he learned to embrace his African identity.
