Nagauta (長唄, literally "long song") is a kind of traditional Japanese music which accompanies kabuki theater. It was developed around 1740. Influences include the vocal yōkyoku style used in noh theater, and instruments include the shamisen and various kinds of drums. The music is a combination of different styles stemming from the music popular during the Edo period.
The shamisen, a plucked lute with three strings, is a very popular instrument in nagauta. Nagauta performers generally play the shamisen and sing simultaneously.
