Villages/Realms should be able to build a form of amphitheater as a structure.
I think it'd be really fun to have a function of them be that they can host a concert where a group (up to a certain size) of players can all provide music with crafted instruments and give all listeners a temporary buff that's based on their averaged charisma.
To avoid having 24/7 bot concerts there could be restrictions like having concerts only last for a defined period and requiring a cool down afterwards before another can be played, and that the people who receive the buff can only receive it once within a given period of time
