Belarusian Pipe-Player (from here)
Double pipes or "Parnyia dudki"
are also referred in Belarus as "Parniouka", "Parnyaty", "Dvojni", "Dvzajchatki", "Dudki", "Pasvisceli","Hoosli", "Dvajchatyia Hoosli". They are made of two pipes of different length. The upper end of each pipe is plugged by a circular insert, with 1/5 of it cut off - "cork" ("shpoont" or "sapoh"). The space between "cork" and the outside wall of pipe makes a narrow crack - "halasnik" for blowing air. There is an alongate whistle cut in the pipe's wall at it's upper end. The bottom end has three holes: 2 at the front - "perabirki" ("finger runs")for finger playing and one - "klapan" ("valve") - in the back. The bottom outlet holes are tied with rope, the tension of which allows to tune two pipes into harmony. Below is a military song suitable for double pipe:
