How do you put on a ballet season when all the dancers are stuck at home? American Ballet Theatre is reconfiguring its spring season into a weekly format of multiple offerings. Monday: “Video Diaries” sees dancers sharing favorite memories of the Met. Wednesday: “Debut Deferred” asks a dancer to talk about the big debut they were preparing to make this season. Thursday: “ABT@80: A Fond Look Back” focuses on legendary ABT dancers and important company milestones. Friday: “Ballet Classes Inspired by the Classics” does just that, gives a class that incorporates phrases from a great ballet. Saturday: “ABT Weekend Talk Series” is an interview, usually of two dancers, on an important role or ballet they would have performed this season. —L.J.
