Hoshana Rabbah is known as the last of the Days of Judgment which began on Rosh Hashana. The Zohar says that while the judgment for the new year is sealed on Yom Kippur, it is not "delivered" until the end of Sukkot (i.e., Hoshana Rabbah, the last day of Sukkot), during which time one can still alter their verdict and decree for the new year. Consequently, the blessing which Jews give each other on Hoshana Rabbah, פתקא טבא (piska tova or pitka tova), which in Yiddish is "A guten kvitel", or "A good note", is a wish that the verdict will be positive.
The Happy Minyan celebrated Hoshaa Rabbah with its conventional cantor, Yehuda Solomon, accompanied by his Moshav Band guitar-partner, Dovid Swirsky, for the first time in many years.
In this spirit, the cantor wears a kittel as on the High Holidays. Since Hoshana Rabbah blends elements of the High Holy Days, Chol HaMoed, and Yom Tov, in this spirit the cantor, in the Ashkenazic tradition, recites the service using High Holiday, Festival, Weekday, and Sabbath melodies interchangeably.
