I want to know the answer to the following question:
What technique did Jesse McReynolds create?
All the background I'm provided with is that "Other major bluegrass mandolinists who emerged in the early 1950s and are still active include Jesse McReynolds (of Jim and Jesse) who invented a syncopated banjo-roll-like style called crosspicking—and Bobby Osborne of the Osborne Brothers, who is a master of clarity and sparkling single-note runs.". Is that enough to answer the question?
Answer: yes
