Sai woke to the rousing first movement of Vivaldi’s violin concerto in C minor, “Il Sospetto.” He lay still for a minute, letting the music wash over him like a gentle Pacific breeze. The room brightened as the blinds gradually opened to the sunlight. Tilly had woken him right at the end of a light sleep cycle, the optimal time. He felt great: refreshed, optimistic, ready to jump out of bed. Narrated by Paul Boehmer.
