Parkapzuk: Armenia musical instrument

The parkapzuk also called the “Պարկապզուկ” in the Armenian local language is a drone less horn- bellied bagpipe that is mostly played by the Armenians. There are six finger holes on the double chanters and the chanters are tuned in a very small degree apart that gives a sound beat as the soundwaves of each interfere and this produces the desired sound tone.
