The Hohner M564036P-D is the product code for the Hohner Pro Harp harmonica in the key of D. This model, often called the “Rock Harp,” is popular for its powerful, focused sound and rugged design. Part of the MS (Modular System) series, it features a durable, moisture-resistant plastic comb for consistent performance. The black-lacquered cover plates and lack of side vents give it a distinctive look and contribute to its loud projection. The key of D is commonly used for playing in the second position (cross harp) in the key of A, making it a favorite for blues and rock musicians.
