"Riverdance" is rooted in a three-part suite of baroque-influenced traditional music called "Timedance". "Timedance" was composed, recorded and performed for the 1981 Eurovision Song Contest, which was hosted by Ireland. At the time, Bill Whelan and Dónal Lunny composed the music, augmenting the Irish folk band Planxty with a rock rhythm section of electric bass and drums and a four-piece horn section. The piece was performed, with accompanying ballet dancers, during the interval of the contest, and later released as a Planxty single. Whelan had also produced "EastWind", a 1992 album by Planxty member Andy Irvine with Davy Spillane, which fused Irish and Balkan folk music and influenced the genesis of Riverdance. Thirteen years later, Whelan was invited to do the intermission piece for another Eurovision Song Contest in Dublin, and composed Riverdance. In a book about Planxty ("The Humours of Planxty", by Leagues O'Toole), Whelan says, "It was no mistake of mine to call it Riverdance because it connected absolutely to Timedance".
