Background and Overview
Janis L. Young Policy and Standards Division Library of Congress

Examples Score of The Four Seasons Recording of The Four Seasons
Concertos; Scores Book about The Four Seasons

Genre or Form? Genre: a category of works that is characterized by a similar plot, theme, setting, situation, or characters Adventure Detective and mystery Western Form: a category of works with a particular format or purpose Encyclopedia Poetry Suite

Genres and Forms in LCSH
LCSH has always included genres and forms Form headings Constitutions Symphonies Topographic maps Waltzes War films Form subdivisions $v Biography $v Exhibitions $v Fake books $v Maps $v Scores and parts

Computer cannot distinguish between form and topical headings Coding is identical (650 field) Form headings can often be used as topics We expect users to distinguish between works of a genre or form and works about it

Examples Old time music Proverbs Spanish language—Dictionaries Spanish language—Lexicography Waltzes Waltz —History and criticism —History and criticism

LCGFT Library of Congress Genre/Form Terms for Library and Archival Materials Coded in a dedicated MARC field (655) Allows computers to distinguish between a topic and a genre/form New interfaces are able to provide specialized limits and searches Result sets match the users’ needs

LCGFT Projects “Finished” Ongoing Moving images
Non-musical sound recordings Cartography Law Ongoing General terms Music Literature Religion Art

Music Genre/Form Project
Collaboration between the Library of Congress and MLA’s Bibliographic Control Committee, Form/Genre Task Force Task Force formed in 2009 567 proposals approved on February 13, 2015

Mediums of Performance
Some LCSH form headings consist of, or include, musical mediums of performance Suites (Bassoon, clarinet, flute, horn, oboe with string orchestra) Operas—Vocal scores with continuo Bassoon, clarinet, trumpet with orchestra Violin and cello music

LCMPT: Library of Congress Medium of Performance Thesaurus for Music Collaboration between LC and BCC’s Subject Access Subcommittee Over 800 terms were approved in February 2014

LCMPT: Library of Congress Medium of Performance Thesaurus for Music Coded in 382 field of bibliographic and authority records Principal goal is access, but may also be used for RDA medium of performance element

Demographic Groups Some LCSH form headings include characteristics of the creator or of the intended audience Arabic language—Textbooks for foreign speakers—English Children’s songs Prisoners’ writings Short stories, American

Demographic Groups LCDGT: Library of Congress Demographic Group Terms
MARC coding 385 field: audience characteristics 386 field: creator/contributor characteristics Undertaken by PSD with assistance of the ALA/CaMMS Subject Access Committee Small pilot vocabulary available in early summer 2015

Demographic Groups LCDGT: Library of Congress Demographic Group Terms
To be assigned When the audience is clearly stated When the creator or contributor self-identifies A German textbook for English speakers An American composer

FACETED VOCABULARIES

Facets Merriam-Webster online dictionary
Facet: def. 2: Any of the definable aspects that make up a subject (as of contemplation) or an object (as of consideration) Synonyms: angle, aspect, hand, phase, side

Facets Simplify discovery
Commercial web sites have been using it for years Allow users to “drill through” individual facets to limit their searches Individual facets can be searched and also used as search limits

Facets Each vocabulary describes a distinct aspect of a work
Coding each aspect separately allows for more flexibility and precision in searching

Facets Example: A collection of short stories about vampires written for teenagers by a French woman Audience: Teenagers Creator: French people; Women Genres/forms: Paranormal fiction; Short stories Subject: Vampires

Facets Each vocabulary is faceted
An authorized term represents one aspect Terms do not overlap in meaning Concerto scores Scores for concertos Concertos Scores

Faceting Each vocabulary is faceted Coding LCGFT: repeated field 655
LCMPT: repeated subfields in field 382 Subfield $a: medium of performance Subfield $b: soloist Subfield $d: doubling instrument Subfield $p: alternative medium of performance LCDGT: repeated $a in fields 385, 386

Status of Music Projects
Music genre/form terms Still negotiating approximately a hundred proposed terms Terms will appear on monthly Tentative Lists PSD is not accepting proposals for new or revised terms at this time Announcement of LC implementation is forthcoming Medium of performance terms Accepting proposals through the SACO Music Funnel LC implemented in spring 2014

Impact on LCSH No immediate impact
All form headings and form subdivisions remain valid Application Non-musical works: continue to assign subject headings as always, in addition to terms from LCGFT Musical works: begin to assign LCMPT and LCGFT if appropriate; may continue to assign LCSH form headings for now

Impact on LCSH Future plans
Existing bibliographic records will be updated Music form headings not used for works about music will be cancelled Music form subdivisions will be cancelled if used only with a form heading

The New Music Vocabularies
Beth Iseminger Harvard University

History and Groups Library of Congress
Music Library Association BCC Genre/Form Task Force Music Library Association BCC Subject Access Subcommittee Began working with Gerry Ostrove from PSD Genre TF 2009, membership Subjects 2011, Hermine chair

Definitions Used by the Task Force
Genre A class, type, or category, sanctioned by convention Form The constructive or organizing element in music Medium of performance The voices, instruments, and other entities necessary to perform a piece Includes instruments, instrumental ensembles, vocal types and ranges, vocal ensembles, mixed ensembles, and objects used as instruments

Early Process Review existing LCSH terms and add any missing terms
Add new terms from reference sources New Grove 2nd edition Garland Encyclopedia of World Music

Sources Used by the Task Force
Including IAML code list, Oxford Companion to musical instruments, RILM thesaurus, Allmusic

Examples of Terms Found Outside of LCSH
from the wiki

Lots of Terms! Using these sources resulted in huge lists of terms, especially for world music genres and instruments The project scope was therefore narrowed to include only LCSH terms, with a few exceptions Long lists might be useful for different project at some point

Decisions Made To separate genre/form and medium facets when they were combined in one LCSH heading To simplify the syntax for medium terms by eliminating the word “music” “violin” not “Violin music” No phrases like “X music” “Violin music” just “violin”

Separating Facets Move from pre-coordinated strings to post-coordinated facets Medium indexed separately, not as part of a string violin 1 / piano 1 Sonatas (Violin and piano) Other facets also separated – language, geography, nationality Post-coordinating these facets offers granularity Necessary in linked data environment ALA Subcommittee on Genre Form Implementation working on vocabs for facets, and on MARC, systems issues

Facets for Music Genre Bluegrass music / Musique concrète Form
Dastgāhs / Motets / Symphonies Medium of performance Soprano voice / Viola / Zither Format Vocal scores Associated place/Geography Kenya / Florence, Italy / Middle West Date of work/Time period 1824 Numeric designation op. 125 Key D minor Language French Audience Children’s songs Subject John Henry (Legendary character)

Facets for Creators Class of persons Music by gay composers
Ethnicity of the creator Music by African American composers Gender of the creator Music by women composers Nationality of the creator Music by French composers

Using Facets Simpler to identify individual facets; easier for training Ex. vocal score of a song for soprano and orchestra Identify medium = soprano with piano Identify genre = song ; arrangement Identify format = vocal score Assign faceted terms: 1 soprano, 1 piano, Songs, Arrangements (Music), Vocal scores Versus the string: “Songs (High voice) with orchestra $v Vocal scores with piano”

Music LCGFT Terms Hermine Vermeij UCLA

Library of Congress Genre/Form Terms (LCGFT)
LCGFT has been around for a while, but the music terms were just added … last week! 567 terms in the first release, with some more in the pipeline.

LCGFT Hierarchy – Top Terms
Music Accompaniments (Music) Arrangements (Music) Art music Chants Dramatic music Folk music Functional music Glitch music Humorous music Medleys (Music) Notated music Popular music Sacred music Songs Sound art Teaching pieces (Music) World music Terms in gray have not yet been added to the vocabulary, but are either scheduled for release or still under discussion. The addition of Art music was a bit contentious, but “Music” really meant two things in LCSH; general music and art music. We wanted to make those two more explicit. We tried to work mostly within the three groups of Art, Folk, and Popular. But, for example, songs and dramatic music can be art, folk, or popular, so they become one of the broadest terms under Music. Functional music is genres and forms initially created for specific purposes—dances, rituals, etc. A few top terms ended up here because they didn’t fit in anywhere else—Glitch music, Humorous music, Sound art. We’re still trying to figure out what World music is, but it seems to be a useful descriptor for some music.

LCGFT – Art music Art music Aʼak
Aleatory music Anthems Ballades (Instrumental music) Barcaroles Cadenzas Canons (Music) Cantatas Carnatic music Chamber music Chinese operas Chorale preludes Concert etudes Concertos Dastgāhs Dialogues (Music) Fanfares Finales (Music) Fugues Gagaku Hát ả đào Hát bội Heike biwa Hindustani music Honkyoku Interludes Kacapi-suling Malhūn Ma'lūf Maqāmāt (Iraqi music) Microtonal music Minimal music Monologues (Music) Musique concrète Nhạ̣c tài tứ Nō music Oratorios Organ masses Overtures Partimenti Pastoral music Phlēng thao Preludes (Music) Program music Quodlibets Ragas Rhapsodies (Music) Romances (Music) Rondos Scherzos Sicilianas (Music) Sonatas Song cycles Songs without words (Instrumental music) Soundscapes (Music) Spectral music Stochastic music Suites Symphonies Taech’wit’a Text-sound compositions Third stream (Music) Toccatas Variations (Music) Vọng cố Delving a little deeper into a few of the hierarchies. Obviously Art music has a lot of narrower terms, including some very common ones we’re all familiar with like Concertos, Sonatas, and Symphonies.

LCGFT – Dramatic music Dramatic music Ballad operas
Ballets (Music) Bangsawan Barong (Music) Ch’anggŭk Chinese operas Congadas (Music) Dialogues (Music) Entremés (Music) Hát bội Hát chèo (Music) Hira gasy Incidental music Katarimono Kecak (Music) Liturgical dramas (Music) Madrigal comedies Masques (Music) Melodramas Modern dance music Monologues (Music) Motion picture music Musical theater Musicals Nāḍagam Operas Oratorios P’ansori Pantomimes (Music) Rappresentazioni sacre (Music) Revues Serenatas Wayang music Dramatic music has a lot of gray terms, mostly because many of these are performing arts that overlap with other subject areas; they will eventually be addressed.

LCGFT – Folk music Folk music Aleke Blues (Music)
Cajun music Calpyso (Music) Celtic music Congadas (Music) Flamenco music Folk dance music Folk-rock music Folk songs Gaitas (Venezuelan music) Guaguancós Hát chèo Huaylas (Music) Huaynos Isicathamiya Klezmer music Kolos (Music) Kuyis Maloya (Music) Mandó Mariachi (Music) Morris dances (Music) Mouth music Música sertaneja Nāḍagam Norteño (Music) Old-time music Palos (Music) P’ansori Plenas Polkabilly music Rebetika Sanjo Schrammelmusik Soca (Music) Sones Soukous (Music) Square dance music Tejano music Vallenato (Music) You’ll notice that Folk music from all cultures and ethnicities are grouped together;

LCGFT – Notated music Notated music Musical sketches Part books
Parts (Music) Scores Service books (Music) Songbooks Tune-books These are all terms you might have seen as subdivisions of LCSH terms in the catalog; using LCGFT they will be separated.

LCGFT – Popular music Popular music Mandó (Music) Mangue (Music)
Agbadja modern (Music) Arabesk (Popular music) Bachata Bailā (Music) Banda (Music) Beatboxing Bhangra (Music) Bikutsi Blues (Music) Boogaloos (Music) Bossa nova (Music) Brega (Music) Cajun music Calypso (Music) Campursari Candombes (Music) Cavachas (Music) Celtic music Chaabi Champeta (Music) Chanchona (Music) Chicha Choros Chutney (Music) Country music Cover versions Cumbia (Music) Dangdut Dansi (Music) Danzones (Music) Disco (Music) Electronica (Music) Enka Forró (Music) Fuji (Music) Funana (Music) Funk (Music) Gaitas (Venezuelan music) Gospel music Gumbé (Music) Habaneras (Music) High-life (Music) Huaylas (Music) Huaynos Jazz Jingles (Advertising songs) Juju music Kanto (Popular music) Karaoke Kaskawi (Music) Keroncong Klezmer music Konkoma Kwaito Kwaya Latin pop Lounge music Lundus Makossa (Music) Maloya (Music) Mandó (Music) Mangue (Music) Mariachi (Music) Mbalax Mbaqanga Mchiriku Minstrel music Modinhas Mornas (Music) Murgas Música sertaneja Música tropical New Age music Norteño (Music) Old-time music Ragtime music Rai (Music) Rap (Music) Rapso Rebetika Reggae music Remixes (Music) Rhythm and blues music Rock music Rocksteady (Music) Rumbas (Music) Salsa (Music) Schrammelmusik Ska (Music) Skiffle Sones Soukous (Music) Soul music Steampunk music Swamp pop music Taraab (Music) Tejano music Timba (Music) Tropicália (Music) Tspapiky (Music) Turbo-folk (Music) Vallenato (Music) Waila music Worldbeat (Music) Zouk (Music) Zydeco music Lots and lots of popular music genres! The hierarchy is a bit shallow here, except for a few deeper areas like Jazz and Rock music, which have a lot of narrower terms.

LCGFT – Other hierarchies
Derivative works Arrangements (Music) llustrated works Fingering charts Informational works Thematic catalogs Instructional and educational works Master classes Teaching pieces Literature Librettos Sound recordings Cover versions Human sounds Player piano accompaniments Remixes (Music) Samplers (Sound recordings) Some terms were identified that fit into already exiting hierarchies like Information works, Instructional and educational works, and Sound recordings.

Highlights of the Vocabularies
Thom Pease Library of Congress

Top Terms Music Art music Dramatic music Chants Functional music Folk music Popular music Popular music Sacred music World music Songs Sound art Arrangements (Music)

New Terms Filling gaps in the hierarchy (Art music, Event music, Functional music, Notated music) Split and separated terms Some new terms (which have literary warrant and scope notes) New terms to replace former form subdivisions Examples: Preludes, Sea chanteys (vs. Sea songs)

Split terms Rounds (Music) Canons (Music) Fugues

What’s not there Psalms and other texts of sacred music not considered forms. Still there: Masses, Requiems Headings denoting medium of performance and/or the number of instruments (Quartets, nonets and String quartets, Piano trios, Woodwind quintets) Terms which just meant popular music or folk music, etc. of a particular country or region.

Passionate discussions
Lots of terms with implicit facets to them (Nations, ethnicities, time periods, language, audience & creator/contributor characteristics) Many terms inherently instrumental or vocal. The loss of cross-references under pre-coordinated strings, and their narrower terms. Narrower definitions of terms long in use

Taking Chances Performing arts terms Event and expression terms
Other general terms proposed Event and expression terms Master classes, Concerts, recitals, Benefit performances, Concert tours, etc.

Form terms Antiphonaries Kyriales Lead sheets Missals (Service books)
Parts (Music) Thematic catalogs (Music) Tune books

Those that didn’t make it
DESPAIR NOT! More tentative and approved lists to come. New terms can be proposed, hierarchies can be changed, and existing terms can be changed. Collaborating with other groups to fill in the hierarchy for terms that border music and are multi-disciplinary

Issues to work through Expression and manifestation terms
Terms which overlap with other projects Performing arts & visual arts, multimedia terms. Events vs. terms in SR/MI hierarchies Just ran out of time to get everything in before the deadline.

LCGFT Best Practices Casey Mullin Stanford University

Provisional Best Practices for Using LCGFT for Music Resources
Even more provisional than the LCMPT best practices! Hot off the press; to be published shortly after MOUG/MLA meeting More detailed guidance will emerge as community application matures You are our guinea pigs. Get to work! LCMPT and LCGFT best practices eventually covered in forthcoming LC manual

MARC 655

MARC 655 $a (Genre/form term) $2 (Source of term)
$2 lcgft Subdivisions ($v, $x, $y, $z) Do not use any subdivisions with LCGFT terms.

General guidelines Generally choose the most specific term available and appropriate. 655 #7 $a Concertos. $2 lcgft NOT 655 #7 $a Art music. $2 lcgft

General guidelines If the work being cataloged combines aspects of two genres/forms that are in different hierarchies, or exemplifies more than one genre/form, give multiple terms as appropriate. An art song: 655 #7 $a Songs. $2 lcgft 655 #7 $a Art music. $2 lcgft An album of pop songs: 655 #7 $a Popular music. $2 lcgft

General guidelines For notated music resources, assign one or more terms appropriate to the format of notated music, in addition to any genre/form terms describing the musical work. Generally observe the RDA definitions of these formats. A set of parts with score of a string quartet: 655 #7 $a Scores. $2 lcgft 655 #7 $a Parts (Music) $2 lcgft A solo piano work:

Art music and Folk music
Do not use the terms “Art music” or “Folk music” for the music of cultures that have no art/folk music division. Use “Art music” for works of art music that cannot be described using more specific terms in the Art music hierarchy, and for works of art music otherwise described by terms that are not in the Art music hierarchy (e.g., Songs, Dance music). A bourrée for harpsichord: 655 #7 $a Bourrées (Music) $2 lcgft 655 #7 $a Art music. $2 lcgft

Chamber music Use “Chamber music” (or one of its narrower terms) for works of art music for 2 or more performers whose medium is described in terms of individual instruments/voices and/or by unspecified ensemble terms (e.g., “bowed string ensemble”). Generally do not use “Chamber music” for: Works for larger ensembles (e.g., orchestra, band, chorus) Art songs with piano Music for solo performers No scope note; use judgment in edge cases! Did we mention the “provisional” part? There is of course a gray area with larger ensembles. Hence, “generally.”

Use with LCSH Until LCGFT terms are fully implemented and a method for converting genre and medium of performance terms currently coded as LCSH: Use LCMPT terms in 382 Use LCGFT terms in 655 Continue to use LCSH terms (Genre/form, medium of performance & mixed headings) in 650 field according to the guidelines in the Subject Headings Manual $b bassoon $n 1 $a orchestra $e 1 $2 lcmpt 650 #0 $a Concertos (Bassoon) 655 #7 $a Concertos .$2 lcgft $a violin $n 2 $a viola $n 1 $a cello $n 1 $s 4 $2 lcmpt 650 #0 $a String quartets. 655 #7 $a Chamber music. $2 lcgft You’re going to hear this multiple times today, but it bears repeating.

So I have to do extra work?
Yes, for now. Still assigning subject headings to musical works in addition to genre/form and medium of performance terms. Eventually, we will not be assigning LCSH to musical works unless they are topical subjects.

What if I don’t know what to do when [insert crazy situation here]?
Check LCMPT and LCGFT best practices Take a guess! Or start a conversation on an list This is new for all of us, and we’re trying to figure out where the holes are. Your problem might eventually make its way into the next version of best practices.

LCGFT & LCMPT in Library Systems

Display Indexing Facets Search Since the development of the LCGFT and LCMPT vocabularies is fairly recent, and their use is not yet totally widespread, many library catalogs are not set up to use them to their full potential. One thing I’ve learned from my local shop is the development of the system itself tends to lag behind the use of new data because coders like to have actual data to use during the programming process. Unfortunately this is a chicken and egg situation. Should the data be created without any practical application, or should the program be developed to promote the use of the data? Sometimes it takes a leap of faith, usually taken by us catalogers, to get things started. There are four areas of the library system which must be developed in order to take full advantage of these new music vocabularies: display, indexing, facets, and search. I will talk a little about each of these aspects and give my thoughts on how systems COULD be developed. Much of what I am about to tell you is really personal opinion, perhaps based on very little actual knowledge of how library systems function. (I’m not a coder.) But these ideas are informed by conversations and committee work which I have undertaken with my local ILS staff.

Display How should LCGFT & LCMPT vocabularies look in the catalog record display? What data should be displayed? Where should it be displayed? Should this data also be displayed in results lists?

LCGFT Display (MARC 655) Locate near subject headings?
Use display label “Genre / Form”? Display 655 $a Do not display 655 “$2 lcgft” Note: There are other genre / form thesauri (and non-thesaurus terms) which are also coded in 655. Some of these 655s contain subfields The display of LCGFT in the 655 field is fairly straightforward. ...

Here’s the bib record for the film Time Bandits as seen in the Stanford catalog. I’m using a motion picture bib record as an example because the music LCGFT terms were just published about a week ago, and I haven’t yet seen any music genre/form terms used in bib records. Maybe one of our other presenters have some examples to show us.

Scrolling down the page, we see that the subject headings and genre headings are separated, but next to each other.

Here’s the same BluRay videodisc in the University of Chicago catalog.

Scroll down, and we see that the subject headings and the genre/form headings combined under the same label “Subject.”

Here’s a screenshot from WorldCat, the old one
Here’s a screenshot from WorldCat, the old one. Here, subject and genre/form have their own labels, but are located quite far from one another, separated by “Find a copy in the library”, which I had to compact in order to get both to appear on the same screen. Display decisions are difficult to make when screen real estate comes

But strangely, the newer WorldCat Discovery doesn’t distinguish between Subject and Genre/Form.

LCMPT Display (MARC 382) Location? Display constant?
Order of MOP terms? Punctuation? The display of LCMPT data in the 382 field is quite a bit more complicated. This is due to the fact that there is a lot of data coded into a single MARC field. Compounding this is a usage in which subfields are repeated and subfield order is semantically important. Many, if not most, library catalogs do not yet even display MARC 382 data, but there are a few that do.

UCLA’s catalog displays “Medium of performance” right next to the subject headings.

Stanford lists “Instrumentation” immediately following the physical description (300 field data).

WorldCat Discovery places “Medium of performance” below the subjects.

But old-school WorldCat puts it further down the page, beneath the physical description.

LCMPT Display (MARC 382) Location? Near the genre / form terms?
Near the physical description? Somewhere else? The question of where in the catalog record display to locate the medium of performance data is a complicated and controversial one to answer. Should the medium of performance be listed next to the genre/form terms, since they work together to describe the music (like our old current subject heading usage)? Or should MOP be placed somewhere else in the bib record display? For scores, the medium of performance is one of the most important pieces of information for users. Maybe if you have a really cool and ambitious systems person, you can convince her/him to locate the MOP data in a different spot depending upon the type of resource: score = near the top; audio = close to the genre/form headings. This question can only really be answered by you and your individual library.

“Medium of performance”? “Instrumentation”? “Performance medium”? “Performing forces”? “Partial medium of performance”? This second question is probably the least troublesome, which display constant is appropriate. Use a sensible term like “Medium of performance” or “Instrumentation.” Be aware that the phrase “medium of performance” may not be clear to many users, including many musicians. The term “instrumentation” may be more generally understood, but are singers included in instrumentation. And don’t forget when you code the first indicator 1 (instead of 0), this indicates a partial medium of performance.

Order of MOP terms? Display in order as coded in 382 Should soloists ($b) always be first? This question can probably be answered by saying: Display MOP terms in the order in which they are coded in the 382 field. This seems obvious to us as catalogers, who spend great energy making sure that MARC fields and subfields are in a certain logical order. But always be explicit with every instruction when talking with programmers, else they may think they are being efficient (or helping you) by ordering subfields alphabetically for display. However, one question which is important to address is the placement of the $b soloists. Should they always come first in the MOP?

Order of MOP terms? Punctuation / labels? The punctuation or labels used in display will probably be the most difficult to work out. We want to find the clearest, but also most concise, way to display the data contained in a MARC field which has no human-readable punctuation (besides that found in the note subfield). There are many options here; some of these ideas will take more development time (by programmers) to implement.

Number of performers ($n)
No punctuation, just a space? violin 1 flute 2 guitar 4 $n in parentheses? violin(1) flute(2) guitar(4) $n preceding term? 1 violin 2 flute 4 guitar What if no $n? In the 382, the number of performers is coded in the $n following the medium term. There are several possible ways a catalog could display this number: no punctuation, just a space; surround the number in parentheses. One interesting possibility would be to program the catalog to display the number before the medium term. And if there is no $n, should the catalog simply display the term alone, or does this require some other indication?

Punctuation between $a or $b terms
Comma? violin(1), flute(1), guitar(1) Semicolon? 4 guitar ; orchestra Pipe? electric guitar(1) | bass guitar(1) | drum set(1) Nothing but space? mixed chorus orchestra

Soloist ($b) “soloist: ” or “[soloist]”?
soloist:oboe(1), band oboe(1)[soloist], band “solo”? solo violin(1) ; solo cello(1) ; orchestra “with”? soprano voice(1) with mixed chorus, orchestra No special indication? 1 piano, percussion ensemble

Alternative MOP ($p) “alternative” or “alternatively”?
violin(1) alternatively flute(1), piano(1) “ or ”? violin(1) or flute(1), piano(1) “/”? violin(1)/flute(1), piano(1) Possibly drop $n from display after $p? violin(1) or flute, piano(1)

Doubling MOP ($d) “doubling”? flute(1) doubling piccolo(1), piano(1)
“+” or “ & ” or “/”? flute(1)+piccolo(1), piano(1) flute(1) & piccolo(1), piano(1) flute(1)/piccolo(1), piano(1) Possibly drop $n from display after $d? flute(1)+piccolo, piano(1)

Note ($v) Display text as written Indicate note by some punctuation
Parentheses or brackets? mixed chorus[SATB] piano(2)[piano, 4 hands] Comma? mixed chorus, SATB piano(2), piano, 4 hands

“Easiest”[?!?] recommendations
Wrap subfields n in parentheses Wrap subfields v in square brackets Change all “$a” into “, ” Change all “$b” into “, solo ” Change all “$p” into “ or ” Change all “$d” into “+” Remove first comma ($a or $b preceding first term) Do not display subfields s or 2 Use a sensible display constant and location

Examples violin(2), viola(1), cello(1)
solo soprano voice(1), mixed chorus[SATB] flute(1)+alto flute(1), piano(2)[piano, 4 hands] Partial medium of performance: violin(1) or flute(1) or oboe(1) * “Legacy” 382s (before publication of LCMPT and best practices) should display fine, although vocabulary will be different

Indexing How should LCGFT & LCMPT vocabularies be indexed to allow proper functionality? What data should be indexed? How should it be indexed?

LCGFT Indexing (MARC 655) Create a separate genre/form index?

Conversion of legacy 650 “subject” headings Requirements
Each 650 should beget, at least, one 382 and/or one 655 field Algorithm should work equally well for score and sound recording records Terms in machine-generated fields must be conformant to LCGFT and LCMPT Machine-generated fields should ideally be conformant to MLA best practices Duplicate fields should be removed 650 fields retained for the time being Fields retained because, among other reasons, other facets (creator/contributor characteristics, audience, language, geography, time period) have to be dealt with soon. Records will be hybrid for some time!

Conversion of legacy 650 “subject” headings Challenges (to name a few)
Implicit medium of performance (e.g., “Symphonies”, “Monologues with music”) Differences in vocabulary LCSH (“mixed voices”) vs. LCMPT (“mixed chorus”) LCSH (“Canons, fugues, etc.”) vs. LCGFT (“Canons” or “Fugues”) Completely new terms in LCGFT (“Art music”) Identifying solo performers True “topical” headings: how to distinguish? By presence of certain values in $v? (e.g., “Songs and music”) Or don’t worry and just let them “fail” the algorithm? Videorecording records? Possible influence on best practices Completely new terms: can only be inferred at best from 650s Topical headings: the system can’t tell which 650s are actually topical headings vs. form/genre/medium constructions. Possible influence: for example, if Art music can’t be automatically assigned to appropriate works that have no specific genre/form, should we be doing so in new records?? On the other hand, should we impose such limits on ourselves going forward?

Fate of existing LCSH headings
LCSH likely to remain in score and sound recording records for some time to come LCGFT/LCMPT algorithm may never be perfect Discovery systems need time to catch up What about works about music? Not all LCSH music headings are appropriate for topical use What’s the granularity “cutoff”? Uncontrolled pattern headings “Cutoff” – see next slide Pattern headings can’t be “cancelled”; must be identified through other means

Fate of existing LCSH headings
Types of topical music headings Topical only, per scope note and SHM Opera (vs. form heading Operas) Usable as topical or form Symphonic poems (presence of $x History and criticism signals topical use) Usable as topical or medium Violin music How granular should topical music headings be? Headings qualified by language Songs, French Headings that combine form/genre and medium Concertos (Piano) (might be worth keeping) Suites (Bassoon, clarinet, trombones (2), double bass, percussion) (maybe not) Headings qualified by Sacred/Secular Cantatas, Secular (or postcoordinate with Sacred music?) Stay tuned!! Again, where’s the cutoff? Many decisions need to be made.

Isn’t this about genre and medium?
Yes! but... Principle goal for LCMPT = access LCMPT also used for RDA medium of performance element = identification

RDA and Medium of Performance
RDA still contains instructions that prescribe how to identify certain mediums of performance accompanying ensembles with one performer to a part solo instruments with accompanying ensemble orchestra/string orchestra/band (especially this one!) solo voices and choruses (and this one!) The JSC Music Working Group will be looking at revising at least some of these instructions in 2015, especially those that have closed lists of terms.

Best Practices for Use with RDA and MARC21 recommends: When recording medium for an access point, also record it as a separate element in the 382 field. When recording medium in a bib record, give the medium that corresponds to that particular expression.

Differences Differences in LCMPT Best Practices and DCM Z1
DCM Z1 recommends adding $n for ensembles DCM = LC’s Descriptive Cataloging Manual LCMPT BPs recommend NOT adding $n for ensembles. MLA proposed $e for number of ensembles which was approved in January 2015. Difference in the 382 field for bib and authority records Authority 382 has no indicators for access Bib 382 has 2nd indicator for access/no access Goal is for these standards to be harmonized – work in progress!
