Recital includes a power adapter, so you can plug it into the wall and play all day, but it also can go mobile running on six of your own D cell batteries.
Where the Recital really sets itself apart is with its teaching tools. In addition to Split mode for different keyboard voices on the left and right sides, a Lesson mode separates the keyboard into two areas with the same pitch and voice. That means a student can sit next to their teacher with both playing the same notes, for a simpler learning experience.
Recital is compatible with Skoove, an online piano-instruction service. Skoove listens to your performance to give real-time feedback, with adjustable tempo settings to match your skill level. Better yet, Recital isn't just compatible with the standard Skoove: it also comes with a free three-month subscription to Skoove Premium to unlock all of the lessons and songs.
Finally, when you know you're a virtuoso, the Recital has a sustain pedal input, USB-MIDI connectivity, and RCA stereo output, so you can expand your keyboard's capabilities to meet your own.
