Rebetiko is a genre of Greek music that emerged in the early 20th century, particularly among the urban working class. It reflects the struggles and experiences of marginalized communities, often addressing themes of love, loss, and social issues. The music typically features instruments like the bouzouki, baglama, and guitar, creating a distinctive sound that resonates with listeners. The lyrics of Rebetiko songs are often poetic and deeply emotional, drawing from the rich cultural heritage of Greece. This genre gained popularity in the 1920s and 1930s, especially in cities like Athens and Thessaloniki, and has since influenced various musical styles both in Greece and abroad.
