For popular/traditional music, there are detailed instructions under SHM H 1916.5 Music: Jazz and Popular Music and H 1917 Music of Ethnic, National, and Religious Groups. As yet LC has not issued guidelines or established headings for form/genre in music; continue to use 650.
For area studies, there can be overlap of the SHM guidelines for Popular music (H 1916.5) and Music of ethnic/religious groups (H 1917); the choice of subject can be based on a combination of both instruction sheets.
H 1916.5 Jazz and Popular Music
Under 1.b: "Assign the headings Popular music or Popular instrumental music when more specific headings for style or genre are not appropriate" If the specific heading cannot be assigned a chronological subdivision, it would be appropriate to pair it with Popular music/Popular instrumental music to bring out the chronological subdivision.
If the recording includes both vocal and instrumental music, use Popular music. Use Popular instrumental music for recordings consisting entirely of instrumental music.
2. "Geographic and chronological subdivisions. Use geographic and chronological subdivisions for all items to which the subdivisions apply, collections and individual works."
2c. Special chronological subdivisions for certain headings.
The following chronological subdivisions may be used under Popular music: ‡y To 1901; ‡y 1901-1910; ‡y 1911-1920; etc. by decade.
More specific headings with chronological subdivisions:
Popular instrumental music ‡y To 1901; ‡y 1901-1910; ‡y 1911-1920, etc. by decade
Rock music: ‡y To 1961; ‡y 1961-1970; ‡y 1971-1980, etc. by decade
The other headings with chronological subdivisions are for American popular music: Jazz, Bluegrass music, Blues (Music), Country music (i.e., popular music genre associated with rural, southern, and western U.S. & Canada; do not use for rural traditional or popular music of other countries).
"2c.(2)(b.) Performed music (sound recordings, moving image materials, etc.). Select chronological subdivisions on the basis of when the music was popular, or if that is not known, by the date of recording, etc."
H 1917 Music of Ethnic, National, and Religious Groups
Basic pattern for traditional music sound recordings uses a combination of these categories of headings. Unlike popular music, chronological subdivisions generally are not assigned.
a. 650 _0 ‡a [ethnic or national group] ‡z [place] ‡v Music.
b. 650 _0 ‡a [headings for music of individual religious groups] ‡z [place]
c. 650 _0 ‡a [ heading(s) for musical genre, type, or style, for ballads and songs, or for songs implying national emphasis].
and, as appropriate,
d. 650 _0 ‡a [heading(s) qualified by language of text
e. 650 _0 ‡a Musical instruments ‡z [place].
f. [other headings as applicable]
To navigate LCSH when searching for specific musical genre terms associated with a place, search under Popular music--[place]; Folk music--[place] and check out the NT lists under them. However, note that a few headings for traditional music forms that are popular in the Western world may be listed under Popular music rather than Popular music--[place]: Bhangra (Music), Celtic music, Klezmer music, Latin pop (Music), Salsa (Music), Zouk (Music).
a. If an ethnic group can be identified, use 650 _0 ‡a [ethnic group] ‡z [place--if appropriate] ‡v Music. However, use this pattern for national groups only if the place would not be the national group's own country. For music of the national group in its own country, use c. or d. below. Note that the restriction does not extend to music of a religious group identified with a country.
650 _0 ‡a Jews ‡z Poland ‡v Music.
650 _ 0 ‡a Ukrainians ‡z Poland ‡v Music. --but not:
650 _0 ‡a Ukrainians ‡z Ukraine ‡v Music.
b. Music of individual religious groups is not applied to Christian denominations. In LCSH, the established religious groups' musics should all be under Sacred music in the NT (narrower term) list in LCSH.
c. To bring out genre, type, or style, and also to bring out the locality, use one of the following with the appropriate geographic subdivision:
- 650 _0 ‡a Music
- 650 _0 ‡a Folk music
- 650 _0 ‡a Popular music
- 650 _0 ‡a Dance music
- 650 _0 ‡a Folk dance music
- 650 _0 ‡a Patriotic music
According to H 1917, it is no longer correct practice to assign Folk music to the music of a culture that does not distinguish between the art, popular, and folk genres; instead, the correct practice is to assign Music--[place]. [H 1917 gives no date when the practice changed.] LC does not give any explicit examples of such cultures, but in the list of general examples, the Quechua Indians of Peru are assigned Music--Peru; the Kabre people of Togo are assigned Music--Togo. In contrast, the French-Canadian music of Quebec is assigned Folk music--Quebec; traditional music of Hungarians is assigned Folk music--Hungary. Base your decision on existing precedent in recently cataloged LCSH. If there is no precedent, work by analogy--if Quechua Indians are assigned Music--Peru, then there is sufficient warrant to assign Music--Peru rather than Folk music--Peru to a recording of Jivaran Indians' music.
d. Place and language.
1. For music of an ethnic group from one country now living in a foreign country, bring out both countries in the subject array.
2. Use the language qualifier for songs (ballads, folk songs, children's songs, etc.) for up to 2 headings to bring out the original language of the songs. If the songs are sung in a translated version, do not bring out the translation language or use --Translations into [language]. For 3 or more languages don't add a language qualifier unless the languages are related, e.g. Ballads, Slavic. Also do not qualify by language song headings with a national emphasis: National songs, Political ballads and songs, War songs.
[e. Musical instruments. The array given in H 1917.5 2e. only applies to books about the topic & should not be used for sound recordings. ]
