Unlike most Muslims, the Ismailis are not shy of expressing their theology and worship of God in song-form, with musical instruments and voice. This is not the Qur'anic recitation you'll hear from the *muezzin*. This is a body of 13-15th century Psalm-like compositions, differing from the works of David, Asaph and others in that the score, the melody, the music has survived through the years.
