A shofar (/ʃoʊˈfɑːr/[1] shoh-FAR; from שׁוֹפָר, pronounced [ʃoˈfar] ) is an ancient musical horn typically made of a ram's horn, used for Jewish ritual purposes. Like the modern bugle, the shofar lacks pitch-altering devices, with all pitch control done by varying the player's embouchure. The shofar is blown in synagogue services on Rosh Hashanah and at the end of Yom Kippur; it is also blown every weekday morning in the month of Elul running up to Rosh Hashanah.[2] Shofars come in a variety of sizes and shapes, depending on the choice of animal and level of finish.[3]
