The 76-key keyboard (a conventional piano has 88 keys) is perfect for playing pop tunes or simple classical pieces. 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. The NP Series keyboards focus on the inspiration and pleasure of playing a piano, featuring the pure sound of one of Yamaha's finest grand pianos.
