Words related to folk-music
Old English folc "common people, laity; men; people, nation, tribe; multitude; troop, army," from Proto-Germanic *fulka- (source also of Old Saxon folc, Old Frisian folk, Middle Dutch volc, Dutch volk, Old High German folc, German Volk "people"). Perhaps originally "host of warriors:" Compare Old Norse folk "people," also "army, detachment;" and Lithuanian pulkas "crowd," Old Church Slavonic pluku "division of an army" (hence Russian polk "regiment"), both believed to have been borrowed from Proto-Germanic. Old English folcstede could mean both "dwelling-place" and "battlefield." According to Watkins, from PIE *ple-go-, suffixed form of root *pele- (1) "to fill," which would make it cognate with Greek plethos "people, multitude," and Latin plebes, "the populace, the common people." Boutkan thinks both the Germanic and Balto-Slavic could be a common borrowing from a substrate language.
Superseded in most senses by people. Generally a collective noun in Middle English, however plural folks is attested from 15c. Old English folc was commonly used in forming compounds (59 are listed in the Clark Hall dictionary), such as folccwide "popular saying," folcgemot "town or district meeting;" folcwoh "deception of the public." Modern use of folk as an adjective is from c. 1850 (see folklore).
"traditional beliefs and customs of the common people," 1846, coined by antiquarian William J. Thoms (1803-1885) as an Anglo-Saxonism (replacing popular antiquities) in imitation of German compounds in Volk- and first published in the Athenaeum of Aug. 22, 1846; see folk + lore. Old English folclar meant "homily."
This word revived folk in a modern sense of "of the common people, whose culture is handed down orally," and opened up a flood of compound formations: Folk art (1892), folk-hero (1874), folk-medicine (1877), folk-tale (1850; Old English folctalu meant "genealogy"), folk-song (1847, "a song of the people," translating German Volkslied), folk-singer (1876), folk-dance (1877).
mid-13c., musike, "a pleasing succession of sounds or combinations of sounds; the science of combining sounds in rhythmic, melodic, and (later) harmonic order," 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 mousikē (technē) "(art) of the Muses," from fem. of mousikos "pertaining to the Muses; musical; educated," 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 pitch probably is 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.
