Leyli and Majnun is an Azerbaijani opera in four acts by Uzeyir Hajibeyov.
It was first performed on 12 January 1908 at the Taghiyev Theatre in Baku. The opera is considered the Muslim world's first opera. The first performance of the opera was led by Huseyn Arablinski and Hajibeyov himself played violin.
Uzeyir Hajibeyov and his brother Jeyhun Hajibeyov wrote the libretto for the opera based on Azerbaijani poet Muhammad Fizuli's poem Layla and Majnun; most parts of the poem remained unchanged.
Thus, the opera Leyli and Majnun became a founder of the unique new genre in musical culture of the world, which synthesizes oriental and European musical forms, resembling a dialogue of two musical cultures of East and West.
