Some food products in Israel carry the mark “Kosher Dairy (Gentile powdered milk)” (אבקת חלב נוכרי). This means that the kashruth supervisor of the factory that produces this food considers it kosher, but duly warns practicing Jews who adopted stricter dietary laws for themselves and don’t eat powdered milk which was prepared by non-Jews. Most secular Israelis hardly know what it means—if they notice it at all—, and some laugh at it, but for some religious Israelis it is quite important. Some practicing kosher Jews are not strict, others adopt strictures for themselves.
Now this came to music, too. Some religious Jews avoid listening to the singing of women, because it is considered non-modest, due to the saying from the Talmud “a voice in a women is shame” (Brachot 24). Rabbis argue about the meaning of it. A tiny minority are so strict that they completely forbid listening to a woman’s voice (except one’s own wife). Many forbid listening to a woman’s singing; some of them argue that listening to recorded woman’s singing is allowed. Some rabbis allow listening to a woman singing as long as the woman and the song are modest.
This is the first time that i saw a CD marked this way. It was sold by a vendor of Jewish traditional music in Jerusalem, who added the sticker himself, knowing that some of his customers may dislike woman singing.
It is good that it is done voluntarily. I hope that the kashruth of music won’t become obnoxious, corrupt and commercialized, like that of food.
