The gaida is a traditional Bulgarian musical instrument, similar to a bagpipe. It is made from a goat or sheep skin, which serves as the bag, and features a wooden chanter for playing melodies. The gaida is often associated with folk music and is commonly used in celebrations and cultural events in Bulgaria. This instrument typically has a rich, warm sound and is played by blowing air into the bag while pressing the chanter's finger holes. The gaida is an important part of Bulgarian heritage and is often featured in performances alongside other instruments like the kaval and tambura.
