The diple, or dvojnice, may be found as a fipple flute or as a reedpipe, but in either case is distinctive in that it incorporates two bores within one body, and thus creates two notes simultaneously. Generally, the left hand fingers a group of holes on the left side of the body, and the right on its side.
All bagpipe diple have a double chanter with two separate single reeds, and have different names throughout Serbia, Bosnia and Croatia. The bag of the bagpipes is called a meh, which consists of a tanned goat skin, the blowpipe is a dulac or gajdenica, through which the air is blown, which is in fact a double chanter used to play the melody and harmony simultaneously. The chanter incorporates two single reeds, one in each bore.
Unlike the majority of European bagpipes, the meh has no drone (trubanj, prdalo, prdaljka), instead playing both a melody and harmony part on the chanter. Though their general form is similar, the meh in different parts of Bosnia varies in chanter tunings, ornamentation, and other small factors. The meh is an untempered instrument, and its specific intonation varies by region.
