Piano Source: Products; Digital Pianos
A DIGITAL PIANO is made up of a keyboard exactly like you find on an acoustic piano. Weighted keys action with hammers that hit electronic sensors, which detect the force you use to strike the keys. You can play softly or you can press harder and play loudly. Usually the sound of each note is played and sampled, sometimes more than 7 times, to get the exact sound and feel. The microchip produces the note with corresponding loudness they were made with.
When you press the keys of a grand piano, the hammer is pushed up toward the string, when you let up on the key, gravity pulls the hammer back down. On an upright piano, the hammer is pushed into the string from the front, when you let up, the hammer returns to starting position. If you try to press a key quickly on the upright, you will find the hammer quits responding as quickly and the key stays in a down position for a second. If you press a key on a grand quickly, gravity immediately causes the key to trturn to position and you can press it again and again. That is why the digital manufactures use the grand piano movement as a model, you can play, more easily with this action. The piano keys are weighted so that you will feel the least resistance at the top of the keyboard just like an acoustic piano.
Most digital pianos offer sounds other than piano. You may want strings, you sound like you are playing with a full orchestra. You may enjoy harpsichord, you will find the digital piano resembles the harpsichord without the velocity in the piano and no sustain. The organ is also a favorite of many with the sound of a huge cathedral organ responding to your touch. You may find learning features on various pianos, some teaching rhythm and some actually showing the music score that you can play along with.
You can listen to the piano through headphones instead of speakers, allowing you to play the piano while the rest of the family watches TV or just wake up in the middle of the night and enjoy yourself! The best part is, you can practice and practice and then, when your ready, unplug and play for your family and they hear it perfectly for the first time.
