For a long time, Cochin Jewish women have sung Jewish songs in both Hebrew and the Malayalam language, which is the language of Kerala, their old home on the Indian coast. The Jewish women in Kerala sang in Hebrew with the men in the synagogue, with their families at the Shabbat table, and other events. This was different from many traditional Jewish communities. Women also knew a lot of Jewish folk songs in Malayalam. Cochin Jews are mostly living in Israel today, and most of the songs they collected are no longer played or even thought about. Some songs, on the other hand, have been recorded in the field and the studio, and a group of women in Cochin is working hard to learn and perform traditional Malayalam songs.
