mid-13c., musike, from Old French musique (12c.) and directly from Latin musica "the art of music," also including poetry (also source of Spanish musica, Italian musica, Old High German mosica, German Musik, Dutch muziek, Danish musik), from Greek mousike (techne) "(art) of the Muses," from fem. of mousikos "pertaining to the Muses," from Mousa "Muse" (see muse (n.)). Modern spelling from 1630s. In classical Greece, any art in which the Muses presided, but especially music and lyric poetry.
The use of letters to denote music notes is probably at least as old as ancient Greece, as their numbering system was ill-suited to the job. Natural scales begin at C (not A) because in ancient times the minor mode was more often used than the major one, and the natural minor scale begins at A.
Music box is from 1773, originally "barrel organ;" music hall is from 1842, especially "hall licensed for musical entertainment" (1857). To face the music "accept the consequences" is from 1850; the exact image is uncertain, one theory ties it to stage performers, another to cavalry horses having to be taught to stay calm while the regimental band plays. To make (beautiful) music with someone "have sexual intercourse" is from 1967.
Jubal was the inventor of musical instruments (Gen. 4:21). The Hebrews were much given to the cultivation of music. Their whole history and literature afford abundant evidence of this. After the Deluge, the first mention of music is in the account of Laban's interview with Jacob (Gen. 31:27). After their triumphal passage of the Red Sea, Moses and the children of Israel sang their song of deliverance (Ex. 15). But the period of Samuel, David, and Solomon was the golden age of Hebrew music, as it was of Hebrew poetry. Music was now for the first time systematically cultivated. It was an essential part of training in the schools of the prophets (1 Sam. 10:5; 19:19-24; 2 Kings 3:15; 1 Chr. 25:6). There now arose also a class of professional singers (2 Sam. 19:35; Eccl. 2:8). The temple, however, was the great school of music. In the conducting of its services large bands of trained singers and players on instruments were constantly employed (2 Sam. 6:5; 1 Chr. 15; 16; 23;5; 25:1-6). In private life also music seems to have held an important place among the Hebrews (Eccl. 2:8; Amos 6:4-6; Isa. 5:11, 12; 24:8, 9; Ps. 137; Jer. 48:33; Luke 15:25).
