Mevlevi sufi is a traditional style of music that is associated with the Mevlevi Order of Sufism. It is characterized by its use of traditional instruments such as the ney (a type of flute) and the kudum (a type of drum), as well as its repetitive, trance-like rhythms. The music is often used in religious ceremonies and is intended to induce a state of spiritual ecstasy in the listener.
