Folksongs cover all subjects related to Jordanian life experience. There are songs for birth, marriage and death, children's songs, songs about love, lamentations, patriotic, religious and work songs, and songs on other themes. The musics of nomadic Bedouins and of settled populations are distinct but interrelated. Following the immigration of Palestinians in about 1948, Palestinian folksongs and traditional art music spread throughout the kingdom. Singers such as Jamīl al-As, Tawfīq al-Nimrī and ‘Abdūh Mūsā influenced the development of folk and folk-related music.
