Diple

Diple, dvojnice, or dvojanke (pluralia tantum) are a traditional woodwind musical instrument in Serbian, Montenegrin and Croatian music.

The flute
The diple may be found as a fipple flute or as a reedpipe, but in either case is distinctive in that it incoporates 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.

Mih
Bagpipes also exist which use a reeded diple as a chanter. Called mih, mjeh, diple with wine skin or only diple, it is played in Istria and Lika, from the  Dalmatia sslands and coast to Herzegovina. The mih consists of a tanned goat or sheep skin, blowpipe (dulac or kanela) through which the air is blown, and a diple (double chanter) on which the melody and harmony are played simultaneously. The chanter incorporates two single reeds, one in each bore.

Unlike the majority of European bagpipes, the mih has no drone (trubanj)", instead playing both a melody and harmony part on the chanter. Though their general form is similar, mih in different parts of Croatia vary in chanter tunings, ornamentation, and other small factors.  The mih is an untempered instrument, and its specific intonation varies by region.
