(hm, I see that jesus2099 beat me to the punch, but I wrote this up before I saw that, so I’m posting it anyway)
I do have a question about instrument ‘families’ that might be relevant to the origin of the issue and how it’s handled further.
There are albums that on the sleeve or in the liner notes say that Artist A plays guitars, or Artist B plays keyboards.
In my understanding that usually means that the artist played more than one guitar or just one keyboard on an album or a song.
The keyboard player might be using both a grand piano with a compact synthesizer keyboard laying on top of it, or he might be using any array of synthesizers, electric piano’s etc.
A guitar player might use different guitars for different tracks, or change guitars within a song for e.g. playing a solo.
So I always understood there was a difference when on an album it says that the guitar player played ‘guitars’ vs. it saying he played ‘guitar’.
The same for the keyboard player playing just one ‘keyboard’ (which often will be specified to be an acoustic piano, a clavecymbel, a Fender Rhodes, etc.), vs. him using several keyboards which are not further specified.
Is MusicBrainz making (and preserving) this distinction for entering and storing this in it’s database?
Without me knowing what actually happened with the ‘families’ mishap, was it perhaps so that entries that said ‘guitar’ were preserved, and entries that said ‘guitars’ were changed to ‘guitar families’?
