After the Storm
Singing, dancing and other entertaining activity is done using different skills depending on which sort of performing art is a question.
Acting is a Guile check
Playing an Instrument is Coordination
Singing is a Charm check
Story-Telling is a Folklore check, though done as entertainment.
Each of these uses can be taken as a specialization of the skill.
All such checks can be used in some contexts as a form of Charm check. Specializations may be cumulative (e.g., an acting specialization can add soul to a Singing or Storytelling check).
