Another relatively simple issue where we just need to pick something, anything: STYLE-591.
My original problem:
Some people use “librettist” as “lyricist” for every classical work (including art songs). Some people use it for opera and the like only, but on all works too. Some people use it only on the main opera / musical / whatever work and use “lyricist” for specific arias, etc.
Canadian Association of Music Libraries uses these definitions (http://www.rda-jsc.org/archivedsite/docs/6JSC-ALA-13.pdf):
An author of the words of an opera or other musical stage work, or an oratorio. For an author of the words of just the songs from a musical, see lyricist
An author of the words of a popular song, including a song or songs from a musical. For an author of just the dialogue from a musical, see librettist
We could use similar definitions.
I think this suggestion is pretty good (and it helps it’s not just based on a whim), but I’m leaving it open to discussion for a week to see if someone has strong disagreements with the proposal.
