Not too unoften, specific genres will have specific instruments related to it, now that genres are an entity how about linking those instrument entities to the new genre entity?

for example:
instruments used in capoeira
instruments used in fado
Afoxé (https://www.wikidata.org/wiki/Q16058159) to Afoxê (https://www.wikidata.org/wiki/Q383530)
Various classical genres will benefit from this too
