(6.15.1.3) Recording medium of performance

Record the medium of performance by applying these instructions, as applicable:
     ° instrumental music intended for one performer to a part (6.15.1.4)
     ° instruments (6.15.1.5)
     ° accompanying ensembles with one performer to a part (6.15.1.6)
     ° instrumental music for orchestra, string orchestra, or band (6.15.1.7)
     ° one or more solo instruments and accompanying ensemble (6.15.1.8)

Record medium of performance as a separate element, as part of an access point, or as both. For instructions on recording medium of performance as part of the authorized access point, 6.28.1.9-6.28.1.11.

If there is more than one part for a particular instrument or voice, record the number of parts.
     Exception:
          If the term percussion is used (6.15.1.4), record the number of players if there is more than one.

Use continuo for a thorough bass part whether it is named as basso, basso continuo, figured bass, thorough bass, or continuo, and whether the individual instrument or instruments of the continuo are specified or not.

For guidelines on recording details about the medium of performance, apply the instructions for medium of performance of musical content at 7.21.

Best practices for music cataloging: If giving the medium of performance as a component of an access point, routinely also give medium of performance in a 382 field. For other works, give medium of performance in a 382 field if readily ascertainable.

The Library of Congress Medium of Performance Thesaurus for Music (LCMPT) gives scope notes for "orchestra" and "string orchestra":

  • orchestra: a large ensemble consisting of bowed string instruments and some combination of wind and other types of instruments, or such an ensemble whose relative size is not specified. For a small orchestra so specified, use chamber orchestra.
    • Keep in mind that the terms in the LCMPT are intended to be used in field 382 of MARC 21 bibliographic records, and not necessarily in the medium of performance of authorized access points. "Chamber orchestra" is not used in authorized access points.
  • string orchestra: an orchestra consisting solely or primarily of string instruments.
    • Use "string orchestra" even when there are keyboard, percussion, and/or plucked instruments. It is the presence of one or more wind instruments that would define the ensemble as an orchestra.
(6.15.1.8) One or more solo instruments and accompanying ensemble
Record the term for the solo instrument or instruments and the term for the accompanying ensemble, in that order.
     ° For the solo instrument(s), follow 6.15.1.4-6.15.1.5 and 6.15.1.11
     ° For the accompanying ensemble, see 6.15.1.6-6.15.1.7

LC-PCC PS: For an accompanying ensemble that has only one performer to a part, use the word "ensemble" preceded by the appropriate qualifying term (e.g., "string ensemble," "jazz ensemble," "wind ensemble") in the part of the medium of performance element that follows the solo instruments.
Best practices for music cataloging: Follow LC-PCC PS.

Vocal music
(6.15.1.9) Solo voices

Record an appropriate term from the following list to identify a type of solo voice:
     ° soprano
     ° mezzo-soprano
     ° alto
     ° tenor
     ° baritone
     ° bass
     ° other terms as appropriate (e.g., bass-baritone, countertenor)

If no specific voice types or ranges can be ascertained for two or more solo voices of different ranges, record an appropriate term from the following list:
     ° mixed solo voices
     ° men's solo voices
     ° women's solo voices
     ° other terms as appropriate (e.g., children's solo voices)

For compositions that include solo voice(s) with chorus, record only the appropriate terms for the chorus (6.15.1.10) and the accompaniment, if any.
 

(6.15.1.10) Choruses
Record an appropriate term from the following list to identify a type of choral ensemble (two or more performers to a part):

If:
     ° the work is not in a "popular" idiom
          and
     ° the preferred title for the work consists solely of the name of a type, or of two or more types, of composition for solo voice (e.g., Lieder, Mélodie, Songs)
          and
     ° the voice is accompanied by anything other than a keyboard stringed instrument alone,

Examples:
flute accompaniment
violin, piano accompaniment

RDA doesn't cover what to do when the voice and instruments are equal in the ensemble. Current practice is to name all the instruments (following 6.15.1.3 to 6.15.1.6) but don't add the word accompaniment.
Examples:
high voice, flute, oboe, vibraphone, violin, cello
medium voice, violin, piano
