Shofar

The shofar is a liturgical horn of a breeding ram, used as a wind instrument. According to Jewish law, the shofar cannot be painted with colors, but it can have engraved decorations.
It is played mainly during the celebrations of Rosh Hashanah and Yom Kippur. On the first day, it is played to mark the beginning of the holiday, and on the second day, it is played at the end to symbolize the end of the Day of Atonement, one of the most important days of the Jewish year.
In the Middle Ages, it was also used on many other occasions such as fasting days, funerals, anathemas, or the beginning of the Sabbath. Today, it is still used in Israel to solemnize official events such as the swearing-in ceremony of the new President of the State.
