A 76-key keyboard (a conventional piano has 88 keys) that allows you to perform piano pieces with greater authenticity, without requiring much space. Although the keys have the same box shape as those on a piano, the keyboard has a lighter feel that makes it easy for beginning pianists to start, rather than the weightier feel of a standard piano keyboard. You can also use headphones with the NP-35 if you are worried about disturbing those around you with your playing.
