Lithuanian folk songs, known as sutartinės, are traditional melodies that reflect the rich cultural heritage of Lithuania. These songs often feature unique harmonies and are typically sung in a call-and-response format. They cover various themes, including nature, love, and daily life, and are often performed during festivals and community gatherings. The songs are an essential part of Lithuanian identity and are passed down through generations. Many folk songs are accompanied by traditional instruments, such as the kanklės, a type of zither. The preservation of these songs is vital for maintaining the country's cultural traditions and history.
