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