Musaf
Ten blasts are blown after Malchiyos, Zichronos, and Shofros, during both the silent Shemoneh Esrei and chazaras hashatz, and another ten are blown during the Kaddish Shalem following Musaf.
During the silent Shemoneh Esrei, when finishing each of these three berachos, wait silently until the shofar is blown. If you are still in the middle of the berachah when the baal tokeia begins blowing, stop, listen, and then continue.
During chazaras hashatz, say the piyutim for the first day of Rosh Hashanah.
If the floor of the shul is made of marble or stone, put down a towel or other separation before bowing during Aleinu.
The Kohanim duchen during chazaras hashatz.
After davening, an additional thirty blasts are blown to “confuse the Satan.”
Rest of the Day
For Kiddush, say Tik’u and Borei Peri Hagafen (but do not say Askinu beforehand).
When bentching, add Yaaleh Viyavo, inserting the words beyom hazikaron hazeh. Additionally, say the Harachaman for Yom Tov, followed by the Harachaman for Rosh Hashanah. See below, “Hosafos,” for the halachos that apply if you forgot to say Yaaleh Viyavo.
It is customary to refrain from sleeping (or wasting time) during the day of Rosh Hashanah.
It is forbidden to prepare today for tomorrow.
The shofar should not be blown on Yom Tov, unless it is being blown for the mitzvah. Children, however, may be encouraged to practice blowing.
Tashlich
After Minchah but before shekiah, visit a body of water with fish and say the nusach of tashlich as printed in the Machzor. When finished, men shake the edges of their tzitzis.
Fish that do not rely on humans for food may not be fed on Yom Tov. It is therefore forbidden to feed the fish during tashlich.
For more on tashlich, see below, “Hosafos.”
After nightfall, women and girls light candles from an existing flame, saying the berachos of Lehadlik Ner Shel Yom Hazikaron and Shehecheyanu.
A man lighting candles should not make the berachah of Shehecheyanu when lighting, as he will say this berachah later when making Kiddush.
A new fruit should be on the table when lighting the candles. Have it in mind when saying Shehecheyanu. If doing so, light the candles right before Kiddush, so you will be able to eat it immediately. Alternatively, wear a new item of clothing. If doing so, the candles may be lit earlier. Shehecheyanu should be said even if no new fruit or item of clothing is available.
A new fruit is placed on the table during Kiddush. When saying Shehecheyanu, glance at the fruit and have in mind to be motzi the fruit with this berachah. However, Shehecheyanu should be said even if no new fruit is available.
Eat the new fruit immediately following Kiddush, before washing your hands for Hamotzi.
The Rebbeim would eat a kezayis of the new fruit, and then say a berachah acharonah, inserting al ha’eitz (for the fruit) but not al hagefen (for the wine).
