I remember reading that a Baal Tokeiah is supposed to wear a new garment on the second day of Rosh Hashanah and it may have something to do with a Shechiyanu Bracha that he makes? Can someone please explain above ?Thanks
Shulchan Aruch Orach Chaim 600:3 records differing practices regarding reciting shehecheyanu on shofar on the second day of Rosh HaShanah (when not on Sunday).
Magen Avraham ad loc. recommends that those who do recite shehecheyanu wear a new garment (presumably as a way of resolving the doubt; even if the shofar doesn’t require shehecheyanu, the new garment does).
