Does Joplin's The Entertainer use a chromatic scale?

Scott Joplin's "The Entertainer" primarily utilizes a ragtime style characterized by syncopated rhythms and a diatonic scale rather than a chromatic scale. While some passages may incorporate chromatic notes for embellishment or tension, the overall structure and melody are rooted in traditional major and minor scales. The piece does not fundamentally rely on a chromatic scale as a central element of its composition.
