A charzarb is a piece in four sections, each with a different tempo. This charzarb belongs to the tradition that Tajiks call music from the mountain (kuhestani), to distinguish it from music from the plains (maqam). More specifically, the piece is from Qala-i-Khum, known as the Gate of the Pamir. Composed in the 1940s by Aka Sharif Juraev in the style of Bukharan wedding songs, it became popular as a masterpiece of Tajik folklore. (During, Levin 2001)
