A shofar is a ram's horn that is used as a musical instrument for religious purposes. It is used on Judaism's high holy days of Rosh Hashanah and Yom Kippur.

The horn is flattened and given a turned up bell by applying heat to soften it. A hole is made from the tip of the horn to the natural hollow inside. It is played much like a European brass instrument, with the player applying his lips to this hole, and causing the air column inside to vibrate.
