“Sefira is “miktzas aveilus” a small part of aveilus. Haircuts and shaving are not done, and live music is not listened to.”
Where does the statement “live music is not listened to” come from? Who, what and where is the source for this? Mechaber? Rema? Mishna Berura? Other nosei keilim? This statement implies “non live” music IS (permitted, to be)listened to. Who or what is the source for the distinction between live and pre-recorded music? Is it limited to music? What about other sources of entertainment such as singing and dancing? Is that permitted? If yes, why is it different than music? Who drew these distinctions and what is the basis for them (assuming they are all correct).
