Renée Fleming and Francis Collins have something unexpected in common: music.

Collins, the director of the National Institutes of Health, plays guitar. Fleming, of course, is a renowned soprano.

Reyna Gordon was an aspiring opera singer fresh out of college when she began contemplating the questions that would eventually define her career.

"I moved to Italy when I finished my bachelor of music, and I started to take more linguistic classes and to think about language in the brain, and music in the brain," she says.
