Sounding brass (χαγκὸς ἠχῶν). The metal is not properly brass, the alloy of copper and zinc, but copper, or bronze, the alloy of copper and tin, of which the Homeric weapons were made. Being the metal in common use, it came to be employed as a term for metal in general. Afterward it was distinguished; common copper being called black or red copper, and the celebrated Corinthian bronze being known as mixed copper. The word here does not mean a brazen instrument, but a piece of unwrought metal, which emitted a sound on being struck. In the streets of Seville one may see pedlers striking together two pieces of brass instead of blowing a horn or ringing a bell.
Tinkling cymbal (κύμβαλον ἀλαλάζον). The verb rendered tinkling, alalazo, originally meant to repeat the cry alala, as in battle. It is used by Mark (6:38) of the wailings of hired mourners. Hence, generally, to ring or clang. Rev., clanging. Κύμβαλον cymbal, is derived from κύμβος a hollow or a cup. The cymbal consisted of two half-globes of metal, which were struck together. In middle-age Latin, cymbalum was the term for a church- or convent-bell. Ducange defines: “a bell by which the monks are called to meals, and which is hung in the cloister.” The comparison is between the unmeaning clash of metal, and music; between ecstatic utterances which are jargon, and utterances inspired by love, which, though unintelligible to the hearers, may carry a meaning to the speaker himself and to God, 1 Cor. 14:4, 7.
