I have obviously never really paid attention to the recording artist field. I thought creating the relationships for the singers only where they actually participate solved the problem of them “showing up” only at the tracks they actually perform .
What is still missing is a concise step by step guide how to enter classical musci data so it turns out in the generally accepted way. (or am I just missing it?)
Hi and many thanks for the replies. I have been so pleased to learn that others have gone before me and are clearly much more knowledgeable and achieving what I had hoped. I am still very much a beginner here.
I am not a coder and chabreyflint’s link is hard work for me but clearly this is the direction I need to go. So much reading!!!
I shall return when I have absorbed a bit more
Many thanks again.

If a release in MB is using D♭. Should we change that to D-flat or do we leave it as D♭. It’s printed on the release as D♭.
Info: Digital releases have it as D-flat, but cover art on back of CD has it as D♭.
I’d probably change it personally, but it’s not very important either way and some people might prefer keeping it. I’d keep the recording as D-flat and the work as D-flat major, I think 
D♭ means D-flat major.
d♭ would be D-flat minor.
But I’d just use D♭ in the tracklist/recording, D-flat for the digitals looks like a bad conversion by someone not realising capitalisation is related to major/minor. It possibly means the intended title should have D♭, and the digital title is just to avoid display problems.
For what it’s worth, very often D-flat means D-flat major, and they will specify “minor” for minor keys.
@loujin : Set relation attributes / Recording-Artist relation attributes
Please have a look at this.
Specimen: https://musicbrainz.org/release/3b0611cd-ea09-4c19-ba9e-891b0b6e67a6 Recording with soloists, 2 choirs & orchestra, where SATB soloists are credited but not set to solo.
Relations editor: Select all recordings.
Recording-Artist relation attributes: Toggle solo
Expected result: SATB soloists only toggle to solo.
Result: SATB soloists & choirs toggle to solo.
I see no reason for choir defaulting with the toggle, but may be missing a point. (Leaving the release as is.)
My first post here hopefully I dont break any hard rules.
I am currently adding tons of early music recordings to the db, mostly (for now) from the labels covered by outhere recordings. For now I am doing almost everything by hand so the metadata are good enough, but could be improved.
I tried to look around but couldnt find any userscript to import from outhere
eg https://outhere-music.com/en/albums/boesmans-bartholomee-foccroulle-mernier-early-instruments
I think it would be a nice one to have if anyone can code it. The website has a very clean structure and the infos are super accurate, down to individual performers per track (booklet+cover+description).
