Special Framework under CSG for Operas

Operas are handled a bit differently than other works. Were they to be formatted using the standard structure, a large amount of redundant information would be added to the title, making it appear cluttered rather than structured.

In a title for an opera, the Movement and Ornamentation frameworks follow the standard structure described above. However, the Work and Opus framework is restructured.

Opera Work and Opus Identification
Opera Name Catalog / Opus Number No. (3)

Note that this is almost the same as the standard Movement framework, except that most of that framework's structure is unused. The sole structural difference between the Opera Work and Opus framework and the standard Work and Opus framework is that instead of:

  • , K. 492 "Le nozze di Figaro"
  • , Op. 8 Our Hunting Fathers

this special structure instead creates:

  • Le nozze di Figaro, K. 492
  • Our Hunting Fathers, Op. 8

Note as well that in the Opera special framework, the opera's name is not enclosed within quotation marks.

It is also worth mentioning again that in the Dramatic Position section of the Movement framework, though "Act" and "Scene" should be translated into the correct word for the CSG language style being used, "No." should not be translated.

Ballet Music

Ballet music normally falls well within the normal CSG structure. However, in some rare cases, it can present difficulties. At one time, short ballets were performed between the acts of operas and other similar musical theater presentations. While most of these have not survived, some rare ones have, and continue to be performed and recorded today.

When such a work is encountered, should the normal CSG structure fail to well fit the work, the special Opera style described above may be used in conjunction with the special style for Variations of Other Works, prefixing the music with "Ballet Music for" in the CSG language style being used for the work.


  • The listing for the opera would be: * Idomeneo, rè di Creta, K. 366 The listing for the ballet music composed for that opera thus would be: * Ballet Music for Idomeneo, rè di Creta, K. 366, in B-flat major, K. 367: III. Passepied


Special Framework under CSG for Variations within Movements

Variations can potentially lead to needlessly long titles. Rather than include each and every variation, where variations do not have tempo changes, link them with a hyphen ( - ). Example:

  • Sonata for Piano No. 6 in D major, K. 205b / KV 284 "Dürnitz": III. Tema. Andante & Variations I - X & Variation XI. Adagio cantabile & Variation XII. Allegro

Work Condition or Version Information

Well-known works will rarely need much, if any additional information to be provided. Some more obscure works, however, may need such information - identifications such as "Appendix", "fragment", "sketch", "original version", "spurious", "doubtful", completion-related information, etc.

Such information may be located in one of two places.

The first has already been described, in the Dramatic Position section, and indicates that a movement of a theatrical work is part of the appendix, not part the normal running of the theatrical work.

Work and Opus Identification
Work Type No. (1 & 4) Instrumentation No. (2) Key Scale Catalog / Opus Number No. (3 & 4) (Work Condition / Version Note) "Common Name"

The second is not included directly as part of any one framework, as such version or work condition information may apply to an entire work, or it may apply only to a single movement within a work. It may be that the entire work is considered spurious, or it may be that one movement from a work has only survived as a fragment. Whichever is the case, when such information needs to be included, we ask that you keep it as short as possible, include it within parenthesis, and place it between the Numbered work of a Work Catalog / Opus Number section and the Common Name section within the Work and Opus Framework.

Except where names are involved, all such note information should be lowercased.


  • Concerto for Violin and Orchestra in D major, K. 271i / K2 271a / KV K2271a (doubtful): I. Allegro maestoso
  • Sonata for Keyboard with 4 Hands in G major, K. 497a/KV 357/1 (Julius André completion): Allegro
