Konkani pop music became popular after Indian Independence in 1947. Henry D'Souza and Helen D'Cruz are known for the Konkani love duet "Kathrina" in 1971 and the love Ballad "Garacho Divo" (Lamp of the House) in the 1970s, while Wilfy Rebimbus' sonnet "Mog Tuzo Kithlo Axelom" (How I Have Loved Thee) from 1977 is popular. Konkani plays, especially religious ones, were written and staged in Mangalore in the 20th century by prominent playwrights such as Pedru John D'Souza, Pascal Sequeira and Bonaventure Tauro. The "Ghumat" was a popular musical instrument played especially during weddings. The instrument has the form of an earthen pot but is open at both sides. One end is covered with the skin of some wild animal, and the other is left open. The traditional theatre form is called "Gumat", and is performed on the eve of the marriage or in connection with the marriage celebrations in the decorated "pandal" (stage). The play is conducted by males belonging to both the brides' and bridegrooms' parties, and usually takes place for two or three nights. The plays performed are usually those of Biblical stories, and their morals are presented with the purpose of educating the bride and bridegroom. This tradition has almost completely died out among the present generation.
