Bard so much needs a mod. Just put in a sequence of fetch quests in dungeons like radiant story quests, given by the Bard's College people. Make a bunch of unique music instruments altered like this: you can equip them like a sword (underneath the instrument graphic they would actually be enchanted weapons with zero damage, it would look a bit weird but what can you do), when you hit the attack key, they play the instrumental music from the tavern bards (give them a slow attack speed so you have to play at least a few seconds), then they trigger an area effect illusion spell such as fear, frenzy or Call to Arms.
