It might be interesting if you could enter a tavern and earn a small amount of money or some food or board for the night.
Appoach an NPC, offer services, play music, collect payment. The player generates an income and has the ability to add music to the environment (weddings anyone?). The rest of us listen to the tune when we enter a tavern or attend a function.
I\'m not saying this would be popular but it could add to roleplaying and could make characters more interesting. Given half the chance it would be nice to roleplay an instrument considering I can\'t use one in real life (musically challenged
).
As for playing, well maybe you could learn new songs or recite common tales to a tune (so newbies could say listen to the sad tale of Laanx). Possibly have macros that are typed along with a tune (make your own tales or songs for guilds and the like). Let imagination be unleashed and see what you can come up with.
Music for a magical sense isn\'t so stupid either, enter a temple and chant to recover mana or whatever your imagination can dream up. Let the bards live!
As for dancing, not sure again for weddings or social occasions maybe, I have no idea.
