The opening number of 42nd Street hits like a thunderclap: fifty feet pounding out a synchronized assault on the stage, transforming the floor itself into a percussion section. This is tap dance at its most visceral—rhythm made visible, sound made physical. But that 1980 Broadway spectacle represents more than entertainment value. It marks the culmination of a century-long journey in which tap's DNA—its rhythmic complexity, improvisational spirit, and floor-as-instrument philosophy—would infiltrate virtually every corner of the dance world.
To understand tap's outsized influence, one must first grasp its essential nature. Unlike ballet or modern dance, where movement often serves visual or narrative purposes, tap treats the body as a rhythmic instrument. The dancer becomes drummer, melody-maker, and visual artist simultaneously. This triple threat—what historian Marshall Stearns called "the marriage of sound and movement"—created a template that choreographers across genres would spend decades adapting, borrowing from, and reinventing.
Shared Roots: Jazz and the Harlem Renaissance
The relationship between tap and jazz dance has never been linear influence but simultaneous evolution. Both emerged from the same crucible: African rhythmic traditions meeting Irish jig and clogging on the Vaudeville circuits and in the clubs of 1920s Harlem. Rather than tap "influencing" jazz dance from outside, the two developed as sibling languages—tap emphasizing footwork and floor contact, jazz dance extending rhythmic ideas into torso isolations and full-body movement.
Jack Cole, the "father of theatrical jazz dance," deliberately mined this shared heritage. His 1940s choreography for Hollywood films like Kismet and Gentlemen Prefer Blondes imported tap's rhythmic complexity into jazz's vertical posture. Cole trained his dancers to execute precise tap sequences, then asked them to maintain that rhythmic clarity while adding torso contractions and hip isolations. The result was a hybrid vocabulary that defined mid-century jazz dance and remains visible in Broadway choreography today.
Fred Astaire and Gene Kelly operated within this same tradition, though their contributions are often misunderstood. Astaire, classically trained in ballet, approached tap as a rhythmic extension of ballroom partnering—note how his 1936 "Pick Yourself Up" with Ginger Rogers uses tap steps to punctuate romantic dialogue. Kelly, conversely, brought athletic physicality and balletic line to tap, most famously in Singin' in the Rain (1952), where his umbrella becomes an extension of the rhythmic body. Neither man simply "did" tap and jazz separately; they synthesized the forms in ways that made the distinction nearly irrelevant.
Broadway's Rhythmic Engine: From Fosse to Noise/Funk
The Golden Age musical theater that followed codified tap's Broadway presence into distinct traditions. Bob Fosse's "show tap"—all splayed fingers, turned-in knees, and sexual insinuation—used tap's rhythmic precision for character revelation rather than pure exhibition. In Chicago (1975), the "Razzle Dazzle" number deploys minimal actual tapping but relies entirely on tap's rhythmic architecture: syncopated accents, sudden silences, and the suggestion of improvisation within tight structure.
Meanwhile, the "rhythm tap" tradition—purer in its musical aspirations—found its theatrical champion in Bring in 'da Noise, Bring in 'da Funk (1996). Savion Glover's choreography for this Tony-winning musical explicitly reclaimed tap's African roots and its connection to contemporary Black culture. The show's "History of Tap" sequence traces the form from slave ships to subway platforms, positioning tap not as nostalgic entertainment but as living, evolving art. This reframing opened doors for tap's integration into musicals that treated the form with contemporary seriousness—most notably Billy Elliot (2005), where Stephen Daldry used tap to express working-class defiance and artistic aspiration simultaneously.
Contemporary musical theater continues this bifurcation. Hamilton (2015) incorporates minimal tap proper—Andy Blankenbuehler's choreography draws more heavily on hip hop and modern dance—but its rhythmic sensibility, its use of silence as punctuation and sudden acceleration as emotional peak, owes clear debts to tap's temporal play. For genuine tap integration, one must look to revivals like the 2017 42nd Street or new works like Shuffle Along, or the Making of the Musical Sensation of 1921 and All That Followed (2016), which used tap to interrogate the form's own racial history.
Concert Dance's Hidden Rhythms
Contemporary and modern dance's relationship to tap has been more covert but no less significant. Twyla Tharp, whose 1976 Push Comes to Shove for American Ballet Theatre scandalized ballet purists, built her early career on what she called "urban folk dance"—street forms including tap, translated into concert vocabulary.
