Diple (pluralia tantum; pronounced [dîple̞], from the Greek word meaning "double" or "two-fold") is a traditional woodwind musical instrument from the Adriatic Littoral. It is also known as misnjiče, miješnice, and mih. People in Bosnia and Herzegovina, Croatia, Slovenia, Montenegro, and Serbia play this instrument.

The flute

The diple is a reedpipe instrument that has two separate hollow spaces inside its body, allowing it to produce two notes at the same time. Usually, the left hand covers a set of holes on the left side of the instrument, while the right hand covers holes on the right side.

Droneless bagpipes

The bagpipe diple has a double chanter with two separate single reeds. These instruments originated in coastal areas of Dalmatia, Bosnia and Herzegovina, and Montenegro, where they have small differences. The bag of the bagpipes is called a mih/mêh/mijeh/mješina, and it is made from tanned goat skin. The blowpipe, called a dulac or gajdenica, is used to blow air into the instrument. This blowpipe is actually a double chanter that plays both melody and harmony at the same time. The chanter has two single reeds, one in each bore. The mijeh or diple is played in areas from Istria in the north, through Lika, Dalmatia, Bosnia and Herzegovina, and into Montenegro.

Unlike most European bagpipes, the meh does not have a drone (trubanj, prdalo, prdaljka). Instead, it uses the chanter to play both melody and harmony. While the general shape of the meh is similar, the instrument varies in chanter tuning, decoration, and other details across different regions of Bosnia. The meh is an untempered instrument, and its specific pitch changes depending on the area where it is played.
