The GO:PIANO is a top-quality portable solution that makes learning easy and fun. It features authentic sound and feel derived from Rolands premium home pianos, and supports Bluetooth for working with music education apps on your favorite mobile devices. Adding in built-in speakers, convenient practice features and more, GO:PIANO is the perfect way to start playing piano. - High-Quality Piano Sounds for an Authentic Playing Experience - GO:PIANOs onboard piano sounds are derived from Rolands highly acclaimed home instruments. Just like a fine acoustic grand piano, each note has its own character, and the tonal color changes seamlessly in response to your touch. This important characteristic will inspire you to improve quickly and continue to spark musical ambitions as your skills grow. GO:PIANO also includes electric pianos, organs and other sounds, allowing you to explore different music styles. - Learn the Right Way With Standard-Size Piano Keys - While GO:PIANO is extremely portable, its keyboard still provides authentic feel and response. The 61 keys are standard size and shape, and offer playing surfaces that emulate the natural feel of an acoustic grand piano. This is a critical factor when starting out on the piano, as it provides a smooth transition when moving to a more traditional instrument in the future. And when you do, your GO:PIANO will continue to be a great portable piano for use around the house and while traveling.
