Song facts: “Mannish Boy” was first recorded in 1955 by Muddy Waters. It is a blues standard which is an “answer song” to “I’m A Man” by Bo Diddley.
Harmonica type (Diatonic): Use your 10-hole harmonica in the key of D to jam along in 2nd position. (Notice how the harmonica plays a classic call and response type of them by not playing while Muddy is singing but rather in between the vocals).
