Definitions and abbreviations

Arrangement	An arrangement in OTCL refers to an ‘adaptation of a composition for a medium different from that for which it was originally composed’ (The New Harvard Dictionary of Music). This term is interpreted broadly, and embraces a wide range of procedures such as melody setting, literal transcription, simple reduction and recomposition.
Bach Digital	An online scholarly resource providing access to digitized scans of musical sources, work and source catalogues, as well as literature related to Johann Sebastian Bach and composers from the Bach family (www.bach-digital.de)
Concordances	Different versions of the same piece sharing the same LWV number, even though these arrangements are in most cases not truly concordant with each other.
Gallica	The digital library collection of the Bibliothèque Nationale de France (gallica.bnf.fr)
Genre	Genre derived either from the title or LWV to facilitate searching. Some pieces in this repertory belong to distinct genres such as chaconnes and gavottes. However, many terms, such as air, entrée, ritournelle and rondeau do not necessarily imply distinct genres. For example, many rondeaux are also dances, and many airs are also entrées. In certain cases, omitting genre in searching could yield better results.
Keyboard	Harpsichord, organ or clavichord. The majority of arrangements are idiomatically suited for the harpsichord. A few arrangements survive in organ sources (e.g., Møllersche). Generally, I have adopted the term ‘keyboard’ to allow for the possibility that some arrangements might have been intended for the organ and even the clavichord.
Location	Existing numeration of pages or folios in the source. The folio format is identified by a number followed by the letter ‘r’ or ‘v’ (recto or verso; e.g., 16r–17v).
LWV	Schneider, Herbert. Chronologisch-Thematisches Verzeichnis sämtlicher Werke von Jean-Baptiste Lully (Tutzing: Hans Schneider, 1981)
Mode	In the search page, the option ‘mode’ serves to distinguish between major and minor keys.
Numeric code	The string of numbers derived from the theme to facilitate searching and identification. Seven numbers are used, from ‘1’ representing the tonic through ‘7’ representing the leading note. This code ignores rhythms, registers, accidentals, ornaments and barlines. The key and time signature of each piece, which are indicated separately, are also ignored.
Original Source	Manuscript or printed source. For a comprehensive list, click ‘Browse Original Sources’.
Original Title	Title furnished by each source with its original spelling.
Pitch	Pitches are referred to using the standard Helmholtz system by italicized letters, in which middle C is designated c’.
Provenance	Provenance and dating of manuscript sources, following Gustafson 1979, Gustafson and Fuller 1990 and Gustafson 2018.
Scribe	Nomenclature of scribes (A, B, C…) follows Gustafson 1979, Gustafson and Fuller 1990 and Gustafson 2018. Identity of scribe, if known, is indicated in ‘Notes’.
Time	Time signature or meter.
