Answer
The traditional fingerpicking style preceding Earl Scruggs' revolutionary three-finger picking technique was known as "clawhammer." It involved a downward picking motion using the指甲of the thumb, index, and middle fingers, resembling the movement of a claw striking a hammer. Clawhammer allowed for a rhythmic, syncopated sound that characterized traditional bluegrass, folk, and old-time music before Scruggs' innovations took the spotlight.
