The Italian rite, unique among Jewish rites, has preserved up until very recently the custom recorded in the Talmud, Masekhet Tagnanith, for communally declared fast days. In this rite, sometimes referred to as the Twenty-Four Blessings, six more blessings are added to the liturgy — the Zikhronot and Shofrot portions more commonly recited on Rosh haShanah, and four different psalms, all interspaced with a poetic litany on behalf of the ancestors’ merit and shofar blasts. It’s a fascinatng service!
