The Hohner 64 Chromonica, as the name suggests, is a chromatic mouth harp. However, it’s not just any chromatic. It has some real elegance and style. It has round holes, which make it comfortable to play. It also has 64 reeds and a 4-octave range. Many similar harmonicas only cover 3 octaves. That’s why the Hohner 64 Chromonica is extremely popular among professionals. The extended range makes it fantastic for playing not just blues, but anything from pop to classical music. This harmonica is the cream of the crop when it comes to look, comfort, and sound. This step up from the Chromonica 48 is great for musicians that like to experiment.
