Walter Brown "Brownie" McGhee was an American folk and Piedmont blues singer and guitarist, best known for his collaboration with the harmonica player Sonny Terry.

Piedmont blues refers primarily to a guitar style, which is characterized by a fingerpicking approach in which a regular, alternating thumb bass string rhythmic pattern supports a syncopated melody using the treble strings generally picked with the fore-finger, occasionally others. The result is comparable in sound to ragtime or stride piano styles. Blues researcher Peter B. Lowry coined the term, giving co-credit to fellow folklorist Bruce Bastin. The Piedmont style is differentiated from other styles, particularly the Mississippi Delta blues, by its ragtime-based rhythms.
