As a composer who studied music and mathematics, I have always found numbers, structure, and science accessible touch-points. But something more interesting evolved over the past several years as I returned to the Hungarian psychologist Mihaly Csikszentmihalyi’s work on “flow.” Coined in 1969, he defined flow as “the state in which people are so involved in an activity that nothing else seems to matter.” No surprise then that some of his first participants were composers: this is a constant aspiration.
