Recording form of work (RDA 6.3)

Record form of work as a separate element, as part of an access point, or as both.

Best practices for music cataloging [3]: If giving form of work as a component of an access point [6] (i.e., preferred titles consisting of the name of one or more type of composition [7]), routinely also record form of work in a 380 [5] field.
For other works, record form of work separately in a 380 field if readily ascertainable.
Prefer controlled vocabulary such as Library of Congress Genre/Form Terms for Library (LCGFT) (See Commonly used music terms in the Library of Congress Genre/Form Terms [8].

For consistency, capitalize the first term.

When terms do not come from a controlled vocabulary, use the singular form.

Do not record in a 380 field types of composition [7] terms that are:
   ° terms indicating a number of performers (e.g. Duets)
   ° tempo markings (e.g., Allegros)
   ° other generic terms that do not convey formal characteristics (e.g., Pieces, Music).
