Definition of a classical work
Works belonging to the "classical music" genre should either have at least one known recording or performance (even if it is not currently in the MB database) or should be the most recent common ancestor to two Works which are in the MB database.
Works should be entered into MusicBrainz using the boundaries decided by the composer, as printed in the score. Some special cases:
"Menuet - Trio"
In unnumbered operas (Wagner, for instance), sometimes an act is the smallest entity you can enter. See "excerpts" below for how to deal with popular arias and choruses.
Sometimes works are published in "collections". This is common for songs and shorter instrumental pieces, but can also happen with larger works like piano sonatas. These works can be interesting to have as "containers", but should not be treated as a main work with parts. Note: In general you should only add collections as works if the composer was involved. Do not enter things like "All piano sonatas by Beethoven" as works in MusicBrainz.
Linking recordings to works
Sometimes recordings and works don't match exactly.
