ABBA - "Dancing queen"

This was written by Abba members Bjorn Ulvaeus and Benny Andersson. They were inspired by Queen Silvia, who married King Gustaf XVI of Sweden in 1976. Abba performed this at a televised tribute to the couple the day before they were married.

The song preceded and contributed to the huge popularity of disco music in the late seventies. Although it does not contain many of the most common key characteristics of disco music, it has come to be considered as one of the best examples of this genre. This is somewhat ironic as its relatively slow tempo and syncopated rhythm make it quite difficult to dance to.

Its introduction of piano and hummed vocals is one of the most identifiable sections of ABBA's music. Another unusual aspect of the song is that it begins with its chorus.
