Chrometta 10 Make It Look Easy This harmonica is a great introduction to the art of chromatic playing. Its user friendly design includes an enclosed mouthpiece and slide mechanism which allows you to blow straight at the reed plates, creating a tone that is clear and consistent with strong projection. The enclosed cover design insures a rich, full resonance. The Chrometta 10 has additional notes extending down into the lower register as far as G3, which is the lowest note found on the violin.
