If you’ve never seen a smile that’s bigger than its body, that is how Fernando Tarango’s energy feels when he enters a patient’s room. It is gentle and wise, and it emanates an unassuming kindness that puts people at ease. His music fills the room and opens a space in which patients experience not so much a performance as a presence of mind and spirit. And when that spirit moves them to raise their own voices in song, Fernando graciously gives them the stage. But they don’t need a spotlight, because they’re already lit from within.
