A light, portable piano-style keyboard with just the functions you need The 61-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-15 if you are worried about disturbing those around you with your playing. We recommend this model to: - People with a casual desire to learn the piano - People with little space in their home (1052 mm x 260 mm x 104 mm) (41-7/16x 10-1/4x 4-1/8) - People worried about lacking strength in their fingers - People who don't want those around them to hear their playing - People who want a MIDI keyboard to enter data
