Would a woman rapping to a beat be considered Kol Isha? As we are looking to record a rap for a fundraiser we are doing and want to have women involved.
Men may not listen to woman rapping. This is included in the rule “קול אשה ערוה” .
Since one is still benefiting from her voice even in a non normal way of singing this is also included in the prohibition.
This is similar to the Halacha that one may not stare at women’s clothes intending to benefit from seeing them.
