The parkapzuk (Armenian: Պարկապզուկ) is a droneless, horn-belled bagpipe played in Armenia. The double-chanters each have five or six finger-holes, but the chanters are tuned slightly apart, giving a "beat" as the soundwaves of each interfere, resulting in a penetrating tone. Researchers in 1996 and 1997 noted they recorded one of the last active pipers of that time. Some sources indicate that the parkapzuk is single chantered, while others indicate it is double-chantered like the tulum.
