The shofar of Rosh Hashanah should be from a wild goat, straight, and [with] a gold-covered mouthpiece, and [with] two trumpets at the sides.  The shofar blows long and the trumpets blow short, for the commandment of the day is with the shofar.

On fast-days, they are of rams’ [horns], curved, and with silver-plated mouthpieces, and with two trumpets in the middle.  The shofar blows short and the trumpets blow long, for the commandment of the day is with the trumpets.

The Jubilee year is similar to Rosh Hashanah regarding the blowing [of the shofar] and the benedictions.  R’ Yehudah says: On Rosh Hashanah [we] blow with rams’ [horns], and on the Jubilee years with wild goats’ [horns].

Ashofar that was split and he glued it together, it is invalid. If he glued together broken pieces of a shofar, it is invalid. If there is a hole [in the shofar] and he sealed it: if it hinders the blowing, it is invalid; and if not, it is valid.
