NB: I've posted many in this series under the subject Who First Said It?
EG: Who First Said It? - No music during Sefira
Q1) What is the earliest source that requires Mourning During S'firat Ho'Omer?
The Talmud does record that Talmidei R Akiva perished during Sefirah
However, AFAIK the Talmud does NOT prescribe any mourning rituals to commemorate this tragedy.
So - Who First Said It?
What is the earliest source for observing Mourning during Sefira?
Q2) What is the earliest source that prohibits passively hearing Music During S'firat Ho'Omer?
I recently received this fax:
"The counting of the Omer is from Tuesday 3/30 until Monday 5/17.
Please be advised that no instrumental music may be played in the restaurant or catering facility during this time."
Well, much of this is self-evident but let's parse it anyway
A. First of all, what is the earliest source for the prohibition of simply hearing instrumental music during S'fira?
B And what is the specific concern about being subjected to someone else's music and merely listening passively? Is there an issur hana'ah in being around music during s'fira?
[OTOH When I lost my Dad A"H I *did* at times request that my office mate cut off his radio]
C. Notice this is for the entire period, not just 33 days
D. For a catering facility - whose being addressed? Few Customers are to be found in the commissary so it seems only the Mashgiach or potentially a few frum workers are impacted.
E. What about this issur is so important so as to motivate a fax a notice to each facility?
The main thrust is the same, when did S'fira and music first get linked?»
Q3) What were the earliest documented restrictions during S'fira?
