The kobza is a traditional stringed musical instrument from Eastern Europe, particularly popular in countries like Ukraine and Poland. It typically features a wooden body and is played by plucking the strings with the fingers or using a plectrum. The kobza has a rich, resonant sound and is often used in folk music ensembles. Historically, the kobza has been associated with the Cossacks and has roots that date back several centuries. It is similar to other string instruments, such as the lute and mandolin, but has its own unique characteristics and playing style. The kobza continues to be an important part of cultural heritage in the regions where it is played.
