Reminds me of the ARK drums. Would love to play horrible music with friends in Valheim. Be nice to get bonus's for it too. Off the top of my head. It could give a status that prevents comfort decay for a duration. Duration could increase with number of people playing instruments, singing, or dancing. This would give you a reason in gameplay to play songs whilst sailing or walking. My second idea is move speed buff. Ya'll get the idea, I'll bore you no more.
