This classic ragtime work is a staple of early 20th-century American piano music, defined by its infectious syncopated rhythms and stride-influenced accompaniment. Its distinctiveness lies in the juxtaposition of a driving left hand against a syncopated, rhythmic melody.
The primary hurdle is establishing a rock-solid stride left hand while keeping the right-hand syncopations feeling loose and natural.

You should be comfortable at Henle level 4 — meaning you can already play level 3–4 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
