Yamaha Pianicas are small piano-style keyboards that you power with your own breath that produce a sound similar to an Accordion or harmonica. The P-37ERD has the same professional finish and styling as the other P-37E models, but with a brighter and more cutting sound that carries out to the audience in a live performance. Paired with its bold red color, this Pianica is perfect for the professional player looking to be the center of attention!
