Shofar in the context of "Horn (instrument)"

A brass instrument is a musical instrument that produces sound by sympathetic vibration of air in a tubular resonator in sympathy with the vibration of the player's lips. The term labrosone, from Latin elements meaning "lip" and "sound", is also used for the group, since instruments employing this "lip reed" method of sound production can be made from other materials like wood or animal horn, particularly early or traditional instruments such as the cornett, alphorn or shofar.

There are several factors involved in producing different pitches on a brass instrument. Slides, valves, crooks (though they are rarely used today), or keys are used to change vibratory length of tubing, thus changing the available harmonic series, while the player's embouchure, lip tension and air flow serve to select the specific harmonic produced from the available series.

Chazozra, also hazozra, hasosrah, hasoserah, plural chazozrot, hasoserot was a natural trumpet used in religious rituals by the Israelites, made of bronze, silver or silver alloys. The chazozra is mentioned 31 times in the Old Testament and is translated tuba in the Vulgate. The first written description of the chazozra is probably recorded in the 4th book of Moses. The prophet Moses is from Elohim prompted: "And the LORD spoke to Moses and said: Make two trumpets of beaten silver..." (4 Mos 10)

The straight metal trumpet chazozra can be distinguished from the curved natural horn shofar by its design. While the word shofar derives from Akkadian, chazozra is based on the Hebrew consonant root ḤṢR (“housing”, “fence”, derived “tube”). The shape, but not the name, appears to have been imported from Egypt, deriving from the simpler Egyptian military trumpet sheneb, which produced only two notes. The chazozra was usually played in pairs. While the chazozra is attributed to the institutionalized sacred area and the circle of power of the Second Temple, the shofar was part of the magical-mystical worship of God
