³ sn The instructions are not clearly spelled out here. But the trumpets were to be made of silver ingots beaten out into a sheet of silver and then bent to form a trumpet. There is archaeological evidence of silver smelting as early as 3000 b.c. Making silver trumpets would have been a fairly easy thing for the Israelites to do. The trumpet would have been straight, with a tapered form, very unlike the “ram’s horn” (שׁוֹפָר, shofar). The trumpets were used by the priests in Israel from the outset, but later were used more widely. The sound would be sharp and piercing, but limited in scope to a few notes. See further C. Sachs, The History of Musical Instruments.
