Excuse me, in Titanic, what dance did Jace and Ross dance when they met on the lower deck?

Tap dance originated from Broadway in the United States, and it is a folk dance. The English name of TAP DANCE is "tap dance", which means tapping and slapping. It was formally formed in the United States in the 1920s. Before this, Irish immigrants and African slaves brought their folk dances to this immigrant continent, and these folk dances gradually merged to form a new dance form-tap dance.

We learned it in music class.
