A comparison of uniform titles and preferred titles

A comparison of uniform titles (AACR2) and preferred titles (RDA) for musical works

Initial title element (AACR2)/preferred title (RDA): Language (6.14.2.5.1) | Singular vs plural (6.14.2.5.2)
Statement of medium of performance: Number of elements | Implied numbering | Standard chamber combinations | Song and choral accompaniment | Adding medium of performance to resolve conflicts
Further additions: Selections | Language of text | Librettos |Arrangements | Selections/arrangements/language

Initial title element (AACR2)/preferred title (RDA) (6.14.2.5 and LC-PCC PS for 6.14.2.5)
Language (6.14.2.5.1)
In AACR2, when the initial title element was a type of composition, all foreign language forms of the name of that type were translated into the accepted English form when it had cognates in English, French, German, and Italian.
In RDA, when the preferred title is a type of composition, the English form is used whenever the name of the type in another language is a cognate. Those forms of the name that are not cognates are used in the original language.
AACR2:
RDA:
Movimenti, ‡m instrumental ensemble
Movements, ‡m organ, piano, recorders (2), flutes (2), clarinets (2), saxophone, violin, guitar, percussion, viola
     The change in medium of performance follows 6.15.1.5
AACR2:
RDA:
Pezzi, ‡m piano, ‡n op. 24
Pieces, ‡m piano, ‡n op. 24
AACR2:
RDA:
P'esy, ‡m piano, ‡n op. 110
Pieces, ‡m piano, ‡n op. 110
AACR2:
RDA:
P'esy, ‡m piano, ‡n op. 12. ‡p IUmoristicheskoe skertso
Pieces, ‡m piano, ‡n op. 12. ‡p IUmoristicheskoe skertso
     Note that the preferred title is in English; the title of the part remains in Russian.
AACR2: Music, ‡m violoncello
     In AACR2, the word "music" had cognates in English, French, German, and Italian. Therefore, all foreign language forms of the word were translated into English.
RDA: Hudba, ‡m cello
     In RDA, because the word "hudba" is not a cognate of "music," so the Czech form is used.
     The change in medium of performance from "violoncello(s)" to "cello(s)" was implemented with RDA.
Trio sonatas
In AACR2 (25.29C1), the uniform title Trio sonata(s) was used for 17th- and 18th-century works for two treble instruments and continuo that were variously titled "Sonata," "Trio," "Sonate a tre," etc.
This instruction was not carried over into RDA.
In RDA use:
     Trio(s) for 17th- and 18th-century works for two treble instruments and continuo with the title "Trio" (or cognates of it)
     Sonata(s) for 17th- and 18th-century works for two treble instruments and continuo with the "Sonata" (or cognates of it)
     Trio sonata(s) for 17th- and 18th-century works for two treble instruments and continuo with the title "Trio sonata" (or cognates of it)
Singular vs plural (6.14.2.5.2)
In AACR2, it was unclear whether a title would be given in singular or plural form when a composer wrote two works of the same type and used a distinctive title for one of the works.
RDA makes explicit that the title of a type of composition should be recorded in the plural if the composer wrote more than one work of that type with the same title [emphasis added].
Statement of medium of performance (6.15.1.5)
Number of elements
In AACR2, the number of elements that could be named in the statement of medium of performance was limited to three, except when the initial title element was "trio(s)," "quartet(s)," or "quintet(s)."
In RDA, more than three elements are allowed.

Implied numbering
In AACR2, when two or more of a particular instrument or voice was required, the appropriated arabic number in parentheses after the name of that instrument or voice unless the number is implicit in the initial title element.
In RDA, always add the number of parts in the authorized access point when there is more than one part for a particular instrument or voice.

Standard chamber combinations

In AACR2 and RDA until April 2014, the following practice was applied to works for three to five instruments that fall into one of the standard combinations:

Former practice: works for three to five instruments considered to be standard combinations followed the treatment outlined in this table:

Standard chamber combinations Initial title element/preferred title was Trio(s), Quartet(s), or Quintet(s), these terms were used for the medium of performance Initial title element/preferred title was not Trio(s), Quartet(s), or Quintet(s), these terms were used for the medium of performance
violin, viola, cello strings string trio
2 violins, viola, cello strings string quartet
flute, oboe, clarinet, bassoon woodwinds woodwind quartet
flute, oboe, clarinet, horn, bassoon winds wind quintet
piano, violin, cello piano, strings piano trio
piano, violin, viola, cello piano, strings piano quartet
piano, 2 violins, viola, cello piano, strings piano quintet

The April 2014 RDA update eliminated this practice.

Current practice: Name each instrument.
Note: LCSH still uses the names of standard chamber combinations followed by the word "music"; e.g., Piano trio music, String quartet music.

Adding medium of performance to resolve conflicts
In AACR2 (25.31B1), statements of medium of performance were added to identical distinctive uniform titles for two or more different works by the same composer, except when the works were all for the same medium of performance and medium of performance was insufficient to resolve the conflict. Some other element was added to render the uniform titles unique.
In RDA, medium of performance is included even when the works are all for the same medium.
AACR2:

RDA:

Petite suite, ‡n op. 169
Petite suite, ‡n op. 189
Petite suite, ‡n op. 192
Petite suite, ‡n op. 198
Petite suite, ‡m guitar, ‡n op. 169
Petite suite, ‡m guitar, ‡n op. 189

AACR2:

RDA:

Concert studies, ‡n op. 14, no. 1
Concert study, ‡n op. 48, no. 2
Concert studies, ‡m piano, ‡n op. 14, no. 1
Concert study, ‡m piano, ‡n op. 48, no. 2, ‡r E♭
     In both AACR2 and RDA, when the only difference between two distinctive titles is that one is singular and the other is plural, they are considered to be identical.
     Note that medium of performance as well as key was added to the second title
Further additions

The order of further subfields in an authorized access point has changed from AACR2 to RDA:
Damian Iseminger, MOUG-L, 10/8/2014:
"Since Selections is considered a work element in RDA, it should be with the work subfields.
For the remaining additions, RDA prescribes no order, but several of us have advocated for using AACR2 order. Thus:
   ° Sketches,
   ° Arrangement,
   ° Vocal score(s),
   ° Chorus score(s),
   ° Language."

In other words
   ° Work subfields: t, m, n, r, k
   ° Expression subfields: o, s, l

Selections
"Selections" is a work element and should always follow the work title.
