Peşrev (pronounced in Turkish), "Pişrev" (), "peshrev," or "pishrev;" called "bashraf" بشرف in Arabic; is an instrumental form in Turkish classical music. It is the name of the first piece of music played during a group performance called a fasıl (). It also serves as the piece of the "Mevlevi ayini", ritual music of the Mevlevi order, under the name "son peşrev" (final peşrev), preceding "son semai". It usually uses long rhythm cycles, stretching over many measures as opposed to the simpler usul the other major form of instrumental music uses, "saz semai".
