Jeanine Tesori, the Tony winning composer of “Kimberly Akimbo” and “Fun Home,”

talks about her upcoming Metropolitan Opera debut, “Grounded,” and what it’s like when a musical theater composer finds herself working with an 80-piece orchestra and 60-voice ensemble. Also discussed: the launch of the “Kimberly Akimbo” national tour, the revisions she and David Lindsay-Abaire made to “Shrek,” and why “Soft Power,” the musical she wrote with David Henry Hwang, is like the Renaissance Faire.
