Musical influences include funk, soul music. The disco sound has a soaring, often reverberated vocals over a steady “four-on-the-floor” beat, an eighth note or sixteenth note hi-hat pattern with an open hi-hat on the off-beat, and 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.
