Thumris are a form of light classical music originating from the Indian subcontinent, particularly popular in the northern regions. They are characterized by their romantic and devotional themes, often expressing love and longing. Thumris are typically performed in a semi-classical style, allowing for improvisation and emotional expression, making them distinct from more rigid classical forms. These compositions are usually sung in Hindi or Urdu and are accompanied by instruments like the harmonium, tabla, and sarangi. Thumris have a rich history and are often associated with the Banaras and Lucknow gharanas, showcasing the cultural heritage of Indian music.
