MUSIC GENRE/FORM PROJECT Will include approximately 900 terms Terms are mostly derived from LCSH with some new additions Fill out thesaurus hierarchies Reduce bias toward Western classical music Art music Genre/forms currently only present in subfield v Studies and exercises Will be part of the LC genre/form thesaurus (lcgft) Will replace LCSH terms being used to identify a genre or form; subject terms will remain in LCSH LC has given us a deadline of mid-November to complete the project
LCMPT NOW AVAILABLE! LC officially launched Library of Congress Medium of Performance Thesaurus for Music (LCMPT) on February 24, 2014. Approximately 800 terms. Includes most of the medium terms currently in LCSH, as well as some new terms. Can be used in authority and bibliographic records in the 382 field. Eventually to be a replacement for the LCSH subject headings that include medium and are used as genre/form terms. Generally singular, not capitalized.

BEST PRACTICES The 382 portion of the DCM Z1 has been recently updated. MLA is developing some provisional best practices for using LCMPT that will be out shortly. Additions or changes to LCMPT should be submitted through the SACO Music Funnel.
A FEW EXAMPLES Medium of performance: alto saxophone, tenor saxophone, and baritone saxophone: 382 01 $a alto saxophone $n 1 $a tenor saxophone $n 1 $a baritone saxophone $n 1 $s 3 $2 lcmpt Medium of performance: alto voice and piano: 382 01 $a alto voice $n 1 $a piano $n 1 $s 2 $2 lcmpt Medium of performance: flute choir (piccolo, 4 flutes, alto flute, and bass flute): 382 01 $a flute choir $2 lcmpt AND/OR: 382 01 $a piccolo $n 1 $a flute $n 4 $a alto flute $n 1 $a bass flute $n 1 $s 7 $2 lcmpt
IMPLEMENTATION You can use LCMPT right now! At this time, continue to use LCSH music terms in 650s. Consider adding LCMPT terms in 382s in addition to LCSH: 382 01 $a mixed chorus $a continuo $2 lcmpt AND 650 #0 $a Masses $v Scores. 382 01 $a marimba $n 1 $a clarinet $n 1 $s 2 $2 lcmpt AND 650 #0 Clarinet and marimba music. Music LCGFT terms out in the next year or so. Look for a genre/form and medium of performance preconference at MLA 2015. Tell your systems people!
RETROSPECTIVE IMPLEMENTATION??? Once Music LCGFT terms are complete, catalogers may begin using genre/form and medium of performance terms in bibliographic records. Looking into options for converting subject headings in legacy records to genre/form and medium of performance terms. New task force?
