Shulchan Aruch – The Halachot of Rosh Hashanah
Note: The RAMA is in brackets [ ]
Chapter 585: The blessing on the Shofer:
1. One must blow the shofer standing. [The custom is to blow it by the בימה where they read the Torah].
2. Before you blow the shofer, you should make the blessing of לשׁמועה קול שׁופר and שׁהחיינו. [There is no difference if he is saying the blessing for himself or if he was already יוציא (covered) and is covering others, he still recites these two blessings. He should blow: Tekiah-ShevarimTeruah-Tekiah three times. Tekiah-Shevarim-Tekiah three times and Tekiah-Teruah-Tekiah three times. It is better to blow the shofer on the right side if you are able to blow it this way. Similarly, the shofer should be oriented upwards as it says, “G-d rises up with the shofer blast”]
3. If he began blowing the shofer and was unable to complete it, someone else should complete it. Even three or four people may do it through the blessing the first one made: provided that the latter were present at the time of the blessing. Even if one made a blessing and was unable to blow at all, another blows without reciting a new blessing and it is not considered a blessing said in vein.
4. Someone other than the Chazzan should blow the shofer in order that he shouldn’t get mixed up. However, if he is trustworthy to repeat his prayers (in the event he gets confused) then he may do both. [Only shofer blasts that are blown in the middle of prayer the Chazzan is forbidden to blow. But the shofer blasts that are blown separately like before we begin the Mussuf prayer are permitted. If the Chazzan did not blow the shofer on these separate occasions, then the shofer blower who did so should also blow the shofer in the middle of prayer since it is better for the one who began the mitzvah to finish it. It is our custom to announce the names of each shofer blast before the shofer blower blows them. This is a good idea.]
5. One who accepts money for blowing the shofer on Rosh Hashanah, one who accepts money to lead the congregation in prayer, and one who accepts money to read from the Torah on Shabbat and Yom Tov (Holidays), will not see anything good arise from that money.

 The Mishna Brura writes that there are those who divide the shofer blowing. They should do according to their custom since Israel is holy and love the mitzvah.
