A Zoom with grandpa, a negative virus test result, the mastery of a new skill: Such hopeful notes were essential to weathering the prolonged COVID-19 limbo of the past year. And now, spring brings us more high notes: an easing of mask restrictions, some warm and sunny weather and the gradual return of live music. Jackson Holeâs Cathedral Voices Chamber Choir presents a spring concert it has titled âNotes of Hopeâ starting at 3 p.m. Sunday in the Center for the Artsâ amphitheater to the south of the performing arts pavilion. The volunteer community ensembleâs first performance in over a year will feature contemporary and traditional works of Americana, with the voices augmented by the Jackson Hole Brass Quintet and members of the Jackson Hole Symphony.
