The narrative music of Heike Monogatari accompanied by a Heike biwa is called 'Heikyoku' (the music played on the Heike biwa as accompaniment for the recitation of Heike monogatari) (There are also many songs based on Heike Monogatari for the Satsuma biwa and the Chikuzen biwa but they were composed after the early-modern times and are musically quite different from Heikyoku).
平家琵琶を用いた平家物語の語り物音楽を「平曲」と呼ぶ（薩摩琵琶、筑前琵琶にも平家物語を題材とする曲が多数あるが、これらは近世以降に作られたものであり、音楽的には平曲とはまったく違うものである）。
