Perk: Singing based on IQ

[dataweaver]

Frankly, Singing is no more of a physical activity than playing a tuba is. I see no problem with basing both Singing and Musical Instrument off of the same attribute — though if I had to pick one, I'd be more likely to go with Perception than either HT or IQ.

But then, I'm also of the opinion that Perception should be the base attribute for most skills that are primarily about aesthetics, whether it's visual (Artist, Makeup, or Photography), auditory (Mimicry, Musical Instrument, Singing, or Ventriloquism), or olfactory (Cooking). Perception works best for each of these because the most important feature is picking up on subtleties in the medium and whether the overall sensory effect is pleasing (attractive visual, pleasant sound, delicious taste, etc) and adjusting accordingly. These skills are all about the sensory experience.
