Range: Why Generalists Triumph in a Specialized World

by David Epstein

The strict deliberate practice school describes useful training as focused consciously on error correction. But the most comprehensive examination of development in improvisational forms, by Duke University professor Paul Berliner, described the childhoods of professionals as “one of osmosis,” not formal instruction. “Most explored the band room’s diverse options as a prelude to selecting an instrument of specialization,” he wrote. “It was not uncommon for youngsters to develop skills on a variety of instruments.” Berliner added that aspiring improvisational musicians “whose educational background has fostered a fundamental dependence on [formal] teachers must adopt new approaches to learning.” A number of musicians recounted Brubeck-like scenarios to Berliner, the time a teacher found out that they could not read music but had become adept enough at imitation and improvisation that “they had simply pretended to follow the notation.” Berliner relayed the advice of professional musicians to a young improvisational learner as “not to think about playing—just play.”
