There has been a discussion that is related to dancing (Dancing as a skill or talent?) and following the same principle playing on musical instrument will be Coordination + Perform (non-existent skill) and Singing probably Personality + Perform
The problem is that the spirit of the system does not allow multiple attributes to be linked to sine skill, therefore you might have to “invent” separate skills for the different art-related things. But for me it is too much overhead.
You can check the bard (skald it was?) talent tree in the Barbarian book.
