Dvojnice from the pear tree
Diple, dvojnice, or dvojanke (pluralia tantum) are a traditional woodwind musical instrument Croatian music.
The dvojnica is actually two pipes, two jedinkas made from one piece of wood, which can be played simultaneously. The music of the dvojnica is always two-part, usually in thirds, although other combinations between tones are also possible. Like most traditional instruments, the dvojnica is limited in its register of tones. One can play at most six sounds in a given octave. By blowing, it is sometimes possible to play certain tones in several octaves, but the intonation is usually not pure. It is interesting how the slanting of dvojnica towards the mouth of the player while playing can achieve an effect in which one side of the dvojnica plays in the normal and the other side in a higher octave.
From instruments like the gunge, i.e. two chanters made of reed connected together, double chanters (double-pipes) made of one piece of wood with reeds made of reed were developed. These chanters had one more addition called a didak, kutao, or oglavina through which air was blown into the pipe. In this case, the reeds did not have to be placed in the mouth and were therefore protected from damage. Such double chanters were usually called diple. Later, these pipes were woven to the bag of tanned animal skin, so besides the name diple it was also called a diple with bag, barrel, bellow, etc.). These instruments were played in this region in a now completely forgotten manner called predušivanje, or circular breathing. This is a way of inhaling air without interrupting the melody. It is the same way that Macedonians play their zurle and Australian Aborigines their didgeridoo.
Besides the double diplas there were also single diplas, or dipla jednojnicas. They were very similar to the double dipla, but instead of double, they had single (pipe) chanters with a reed made of reed or elder tree wood and from three to six holes for playing.
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.
