The kaba gaida, also called the rodopska gaida, is a type of bagpipe from the central Rhodope Mountains in Bulgaria. It is an important symbol of Bulgarian folk music. The instrument is made from wood, horn, animal skin, and cotton. It is similar to the gaida but has a lower sound and a larger bag. The part of the instrument where the music is played, called the chanter, has a curved end with a six-sided shape. Inside the chanter, the channel is shaped like a cone that gets wider as it goes in. The most common drone tone on a kaba gaida is E.

The song "Izlel e Delio Haidutin," played on the kaba gaida, was included on the Voyager Golden Record. This collection of sounds was chosen to show the variety of human cultures.

The gaida is played during weddings, celebrations, and other events. People in the Balkans say, "A wedding without a bagpipe is like a funeral." Interest in the kaba gaida has grown, and it is now used in ethno jazz music.
