I did some research.
I found this page https://freepsdvn.com/photoshop-action/n...-24634158/
I believe that the process can be easily reproduced by Gimp (without actions).
But in my head I don't remember any plug-in that has this effect.
Basically a musical worksheet in the background (note sheet), Some brushes with dynamic options enabled (color randon), and a selection of the part of the image to be highlighted.
I believe that a gradient should be created with the desired colors, and keep that gradient active when the brushes are applied.
In the case of PS, Action uses the Oil Paint filter, I don't think Gimp's Filter - Artistic - Oilify is similar, maybe some other filter (G'MIC?).
A quick try...
