Questions:
How does Rashi understand the opinion of רבי ירמיה בר אבא who says that everyone agrees the musical instruments were played daily at the Nisuch hayayin of the Korban Tamid even on Shabbos and Yom tov. Was this permitted because they hold עיקר שירה בכלי or because of a different reason?
What is the reason why playing musical instruments are permitted? Is it because the mitzvah of Simcha for the Nisuch Hamayim is only drabanan or because it’s not part of the Avodah?
