For the first time in nearly seventy years at Yeshivas Slabodka in Bnei Brak, where there is little singing during the Yomim Noraim davening, the talmidim sang various portions of the tefillah this week.
Talmidim at Slabodka requested from the roshei yeshiva to sing Hayom Haras Olam and Areshes Sefaseinu, the portions said at tekias shofar during Mussaf‘s chazoras hashatz. They were granted their request.
On the second day of Rosh Hashanah, however, the rosh yeshiva, Rav Dov Landau, said that only Areshes Sefaseinu should be sung, and not Hayom Haras Olam, which, he explained, is required by halachah to be recited with great awe and reverence.

What great news I am so excited
It is not true that they don’t sing at Slabodka. They sing Simcha L’artzecha V’sason l’irecha in chazaras hashatz in every tefilla on Yom Kippur. That’s 16 words!
There is also a unified chant, not quite a niggun but definitely a chant of sorts, at certain piyutim like V’chol Maaminim.
Tur says to sing Baruch She’amar every day.
I heard that one should sing Mizmor leSodah also.
Hayom Haras Olam is sung by many chassidim. I’m sure there’s a hallachic source for that as well.
What makes you so sure?
Lemayseh, I think the student body of that Yeshiva is heavily Chasidic.
It would be interesting to compare the hanhogo there with the hanhogo at Chevron Yeshiva, which also is a hemshech of the Slabodka Yeshiva of Lita.
