The diplica is a very old simple instrument that was once played in different forms in many regions of Croatia. Today, it is preserved only in Slavonia and Baranja. The diplica is usually made of reeds (although it can also be made from the wood of the elder tree, straw, or even from goose feathers). It contains a pipe with several (usually five) holes and a one-way valve also made of reed. Diplicas are most frequently made in the key of E (in this case the rest of the tones of a diplica are: E, F sharp, G sharp, A, B and C sharp), but they can also be made in the keys of C, D, F and G.Sviroke (otoci Olib i Silba)

Due to the unique capabilities of the instrument and by using a special playing technique, one can achieve the effect of two-part playing.

The diplica is a forerunner of bagpipes, the duda, the šurli and other types of mih (bellows). Although it is a very simple instrument, the richness and beauty of its sound is fascinating.
Reed diplicas can be seen in the picture to the left. A sviroka made of rye stems from the island of Silba is shown on the right. Such instruments have been played until recently on the islands of Olib, Silba and Rab. It is interesting that the sviroka was played mostly by women, usually when they would go harvesting. Unlike the other types of diplica in Croatia, the reed on a sviroka is cut upwards, similar to wind instruments in the Middle East, which indicates how long these instruments have been a part of Croatian tradition.
