The traditional musical instruments of Greece can be categorized into three main groups: stringed instruments, percussion instruments, and wind instruments. Some popular traditional stringed instruments mentioned are the bouzouki, baglama, mandolin, guitar, and bass. The lyra of Pontos is a small, solo stringed instrument. Folk music performances often feature combinations of instruments like the baglama, guitar, violin, accordion, and piano accompanying the lyra. Regional folk music styles in Greece pair instruments together such as the daouli zourna in mainland Greece, lute and violin in the islands, and tambourine and lyre in northern Greece.
