It just occured to me... when not looking at it from a purely DnD perspective, bards seem kinda... niche. I mean, singing magically imbued songs is cool, dont get me wrong, but as i think about it, the "standard" for the fantasy team of people was: The tough one with the big sword, The fast one with the two swords, The one with the bow, the one with healing, and the one with magic.
At what point did The Guy who plays music which empowers his allies and/or charms monsters become a mainstay? Was it just the founder of DnD's unique idea? When did the concept of bard first arise?
