In a recent conversation with @CatQuest, he mentioned the Brazilian “bateria” as something he would want to add to MusicBrainz to be able to indicate a lot of instruments are part of it, but which doesn’t really match the current options as it’s not really an instrument in itself. This reminded me that we’re still using “strings [string quartet]” and stuff like that for other standard group combinations (well, I’m just using “strings”, but I know @loujin for example uses “strings [string quartet]”). And we thought we’d like to create a new type of “instrument” (name may be “grouping”?) for these kind of groupings, that would allow us to state, for example, “string quartet includes violin, viola, cello”. It seems like a reasonable thing that for us to store, but I didn’t want to just add this without some discussion - so I’d like to know if people think this would be a bad idea
I think this would also be useful for STYLE-470 (instrumentation for works). It would also allow merging “orchestra performed” into the instrument list, same as with vocals (STYLE-609), to eventually have just one “performed” relationship instead of many.
If after STYLE-609 we have a UI that separates instruments and vocals somehow even if they’re stored the same way in the background, I’d probably also want a third section for groupings (and I’d probably want to move “choir vocals” to be a grouping, eventually, too, but that’s getting ahead of ourselves).
