Q. I learned in Bais Yaakov of the importance of the Shira and how when said with joy it redeems all sins. Does that apply to women also? What if due to the necessary dedication to my children. I can’t daven Shacharis can or should I at least say the Shirah?
A. Indeed when properly said and with the true joy of someone having just crossed the sea and saved his own life and the life of his dear ones, the Shira gains forgiveness for all the sins committed, as Mishna Berurah (51: 17) quotes from the Zohar.
Historically women sang the Shira as mentioned in Parshas Beshalach (15: 20,21) ‘Miriam, the prophetess, Aaron’s sister, took a timbrel in her hand, and all the women came out after her with timbrels and with dances. And Miriam called out to them, Sing to Hashem.’
Horav Aharon Miller Shlit’a mentioned that although women are obliged to recite some tefilos every morning, but not the Shira. However, if recited properly it will atone all sins, as it does for men
