The ceremony consists of the noble eulogy to the Prophet Mohammed, flute solo, prelude, the Circling of Veled and four segments (selam), which form an integral whole and contain different Sufi meanings. The Sema Ceremony is performed with traditional Mevlevi music in spaces where Mevlevi culture can be properly transmitted. The ceremony begins with the Noble Eulogy (naat-ı şerif), which is the score composed by Itri and has been played since the late 17th century. Hymns written by composers such as Pir Adil Çelebi are sung by a trained chorus, which is accompanied by instruments such as the ney (flute), kettledrum and oud. The works of Rumi written in Persian are the basic source of the compositions performed by the musicians and singers during the ceremony.
