Rav Mosheh Lichtenstein, “Kol Isha: A Woman's Voice,” Tradition 46:1 (Spring 2013): 19
In a generation worthy of women who wish to actively participate in giving praise and thanks to God at the Shabbat table, the Passover Seder and in many other settings, and in an era when women personally express themselves in all general areas of life, it is highly obligatory to enable them to express themselves in religious contexts as well. Inasmuch as it is possible to encourage the inclusion of women in the service of God in the context of legitimate halakhic pesak, it is both our privilege and duty to do so.

…the question that had been nagging at me my whole life…was, ‘What am I supposed to do with this gift that I was given, this voice that has power to impact people- and something that is really a deep part of my existence- how can I reach people and still do that within the framework of halacha?’

Now I never felt restricted at all from not being able to sing or dance in public, since I don’t feel I’m good at either one. But there are times at home when you just feel like singing. Then comes the brother’s voice “shhhh!”. I would get this annoyed feeling, and I would feel frustrated. There are some emotions that get expressed through singing, and sometimes you just have a song in your head and feel like singing. My brother would assure me that it’s not meant as an insult, that if anything it shows that my singing may be nice. [Follow-up Comment by the blogger:] Actually this Shabbos, for the first time I stuck up for my little sister when she wanted to sing, and I told my little brother that he can’t tell her not to sing, but rather he should just go away if he doesn’t want to hear.
