Peşrevs are composed of movements called "hane" (lit. "house"), at the end of which there is always an unchanging particle introducing the "teslim" (lit. "handing in") "mülazime" (lit. "that which is inseparable or constant"), i.e. the refrain. Peşrevs are named after the makam used in the first "hane" and usually end with this makam; in Turkish classical music theory, they are said to be "bound" to this makam. There are always modulations to other makams in the "hane"s that follow the first "hane", but with the refrain ("teslim"), the piece always regains the principal mode. At the end of each "hane", a pause is made on the strong degree of its makam, forming a semi-cadence. This is called a "yarım karar" or "nim karar" (lit. "semi-decision"). Peşrevs usually have 4 "hane"s, yet they occasionally have 2, 5 or 6.
