這種鋼琴擁有和傳統鋼琴一樣的造型,但是卻沒有傳統鋼琴上的聲學結構,既沒有琴弦也沒有共鳴板。數碼鋼琴的核心是一臺電腦,它將從傳統鋼琴上採樣下來的各個音的音色一一儲存在內部存儲器中,演奏者按動琴鍵就驅動了一個信號,電腦就將對應的音色播放出來。數碼鋼琴的出現在保證音色和音量的前提下進一步減小了鋼琴的重量和體積,可以讓更多人更方便和更廉價地使用和學習演奏鋼琴。

鋼琴從外形上主要分成立式鋼琴和三角鋼琴。
三角鋼琴是鋼琴最原始的形態,現在一般都用於音樂會的演奏,是一件笨重的龐然大物。為了解決占地的問題,立式鋼琴被發明出來。立式鋼琴採用了一種琴弦交錯安裝的設計方案,有效地解決了空間上的要求和音色音量的平衡問題。只要家中有一小塊空間,都能安放一臺立式鋼琴。
無論是三角鋼琴還是立式鋼琴,其基本結構都是一樣的。由:弦列、音板、支架、鍵盤系統(包括 黑白琴鍵和擊弦音棰)、踏板機械(包括頂桿 和踏板)和外殼共六大部分組成。
鋼琴的音域寬廣,可達7個八度,音量宏大,音色變化豐富,可以表達各種不同的音樂情緒,或剛或柔,或急或緩 均可恰到好處;高音清脆,中音豐滿,低音雄厚,可以模仿整個交響樂隊的效果。

This kind of piano has with the traditional piano same modelling, but actually does not have on the traditional piano acoustics structure, also does not have the string also not to have the sounding board.

The digital piano appearance further reduced the piano weight and the volume in the guarantee timbre and under the volume premise, may let more people be more convenient and uses and studies the performance piano inexpensive.
The piano mainly divides into the vertical piano and the triangle piano from the contour.
The triangle piano is the piano most primitive shape, now generally all uses in the concert the performance, is an unwieldy colossus. In order to solve the occupying a land area of problem, the vertical piano is invented. The vertical piano used one kind of string to interlock the installment the design proposal, has effectively solved in the spatial request chord color volume balanced problem. So long as in the family has a scrap space, all can place a vertical piano.
Regardless of is the triangle piano or the vertical piano, its basic structure all is same. By: The string row, the sound board, the support, the keyboard system (and strikes string sound including black and white key short wooden club), the footboard machinery (including roof bar and footboard) and the outer covering altogether six major part compositions.
The piano range is broad, may amount to 7 eight degrees, the volume is great, the timbre change is rich, may express each kind of different music mood, either just or supple, either anxious or slow may just right; The treble is clear, the tenor is plentiful, the bass is abundant, may imitate the entire symphony orchestra the effect.
