Enhanced Synesthesia

Chris Coolidge (Heroes)
Chris had the ability of enhanced synesthesia, which enabled him to see sound waves as light and meld his emotions with music, effectively drawing large amounts of people to him. Chris apparently used his ability to draw crowds of thousands to his concerts. While being able to see sound, Chris could also produce destructive blasts of sound, as he did with a strike of his guitar.

According to his assignment tracker file, Chris's biological level was 70, cerebral was 80, elemental was 15, and temporal/spatial was 50. His control index was at 73%.

Emma Coolidge (Heroes)
Emma has the ability to see sound waves as beautiful lights. She is able to produce beautiful music from these lights by "merging" her emotions into her power. This causes a sort of entracement for all those around Emma as they become drawn to her side.

This additional aspect of her ability is also not limited to those in her vicinity as she was able to attrack Peter Petrelli from somewhere in New York to her apartment.

Emma has shown that when she feels powerful emotions, such as fear, she is able to force the lights into a concussive blast powerful enough to leave a scar embedded into her apartment wall. She is later able to use this on purpose to blast Eric Doyle, defeating him.
