Disco is a genre of dance-oriented pop music that was popularized in dance clubs (discothèques) in the mid-1970s, and which dominated mainstream pop until the late 1970s. Disco songs usually have soaring, often reverberated vocals over a steady four-on-the-floor beat, an eighth note (quaver) or sixteenth note (semi-quaver) hi-hat pattern with an open hi-hat on the off-beat, and a prominent, syncopated electric bass line. Strings, horns, electric pianos, and electric guitars create a lush background sound. Orchestral instruments such as the flute are often used for solo melodies, and unlike in rock, lead guitar is rarely used.
