Hi, Junior Gill hits all kind of things with his mallets, e.g. vibraphone, marimba and steel pan - known for this album:
There are printed per-track credits, but on tracks he used more than one of his instruments, only ‘mallets’ are mentioned.
But mallets is no MB instrument - what should be chosen? Percussion? Other instrument? I picked ‘percussion idiophone’, because of the explanation, but I’m not really happy with it, and it is probably not what was meant by the credit.
I’d pick “percussion” and rename it “mallets”. That is the more generic term as an idiophone will be too limited to something specific.
If I know that one track has an identifiable Marimba or steel pan heard, then I’d add that in as well. I have done this with a few albums as it is fun to listen and find the details by ear. Or some extreme reading up on “How I made this album” notes. No problem having multiple types of percussion listed on a track.
(But I may not be the best to ask as I’d never select membranophone as it is not a word I have ever heard used outside of this site)
I would put both for this guy. If he is making a point of using his “mallets” in the credits, then I’d make sure to give them a nice loud credit along with any instrument he is hitting with them.
When I see that word, I just imagine the drummer sitting there playing a Kazoo.
