shofar, šofar puhekieltä A ram’s-horn trumpet
1985, Anthony Burgess, Kingdom of the Wicked:

Thaddeus the fluteplayer had, it seems, found a ram’s horn or shofar, and he was blowing this not in the normal manner of an angry summons but so as to produce a melody of four notes, like a camp call to dinner or parade.
