Twenty-five keys sized for small hands give children an early start on piano skills while the record and playback functions let them listen to their own performances and build confidence. Adjustable volume and speed help match the sound level and tempo to different songs and practice needs. The compact 15 x 9.5 x 18.5 in keyboard fits easily in a playroom, and the included 13.5 x 10 x 7.5 in stool provides a dedicated seat for focused playing. A hidden battery box that holds 4 AA batteries keeps power components out of sight, and energy-saving sleep mode helps extend battery life. Rounded corners, widened legs and non-slip foot pads create a stable base, and the removable legs let the MDF and ABS piano body sit on a tabletop or floor as kids grow and their play space changes.
