Explanation:

A fret is a raised element on the neck of a stringed instrument. Frets usually extend across the full width of the neck. On most modern western fretted instruments, frets are metal strips inserted into the fingerboard. ... Fret is often used as a verb, meaning simply "to press down the string behind a fret"

The theme of social protest remained a consistent focus for jacob lawrence throughout his career. in the 1960s lawrence was inspired by news reports and photographs, including images of segregated lunch counter sit-ins and stories of the   freedom riders in the civil rights movement. from the 1970s onward, lawrence's work focused less explicitly on contemporary social issues.
