Transgender singers find voices in Boston choir

In the world of vocal groups, where singers are separated along bold gender lines with little room for gray, the Butterfly Music Transgender Chorus stands out.

Founded last year in Boston, it is one of the country's first choirs reserved for transgender singers. It was created for those who didn't feel welcome at traditional choruses, but it's also one of few places where transgender vocalists can learn how to adjust their voices safely while they're in transition.

At a recent rehearsal, chorus members couldn't hold back smiles as they finished the folk ballad Shenandoah.
