The Nicholas Brothers were an entertainment act composed of brothers, Fayard (1914–2006) and Harold (1921–2000), who excelled in a variety of dance techniques, primarily between the 1930s and 1950s. Best known for their unique interpretation of a highly acrobatic technique known as "flash dancing", they were also considered by many to be the greatest tap dancers of their day, if not all time. Their virtuoso performance in the musical number "Jumpin' Jive" featured in the 1943 movie Stormy Weather has been praised as one of the greatest dance routines ever captured on film.

Tap dance is a form of dance that uses the sounds of tap shoes striking the floor as a form of percussion; it is often accompanied by music. Tap dancing can also be a cappella, with no musical accompaniment; the sound of the taps is its own music.
