I was pretty sad when I found out I couldn't play the flute that you can find.
I've found 5 - and two bows but no violin, and two lutes (along with several broken lutes). Being able to play could be a fun nice thing to do - perhaps playing as you stroll - bards will need access to them to do their bardly magic - and I also see it as a good thing to do to create a distraction for a thief to close in and pickpocket a distracted individual. There is a lot you can do with the instruments if they simply implement it.
