　　鋼片琴為法國米斯泰爾發明。最初的發音體用一係列音叉，亦稱鋼叉琴。1886年正式命名為鋼片琴，實際現在的鋼片琴音條和共鳴管均以鋁制作。鋼片琴外形如小形簧風琴，聲源體為金屬板條，以類似鋼琴的擊弦機擊奏、有踏板制音器控制音響的長短，和鍵盤鋼條琴柏飢但每一鋼音條下方附有共鳴管，放大音量，並使音色清晰純淨。鋼片琴音域一般為CC',4個八度。

　　柴可夫斯基在《胡桃夾子》中用此樂器的纏綿音響來暗示第二幕中《糖果口舞曲》的粘性與甜美。巴爾托克《為弦樂器、打擊樂器和鋼片琴所寫的音樂》為鋼片琴的典型曲例。

Piano

A grand piano, with the lid up. Most pianos are about 150 cm wide. Grand pianos such as the "baby grand" pictured are about as long as they are wide, but a Concert Grand can measure up to 3 m perpendicular to its keyboard.For other uses, see Piano (disambiguation).
"Pianoforte" redirects here. For earlier versions of the instrument, see Fortepiano.
A piano or pianoforte is a musical instrument classified as a keyboard, percussion, or string instrument, depending on the system of classification used. The piano produces sound by striking steel strings with felt hammers that immediately rebound allowing the string to continue vibrating. These vibrations are transmitted through the bridges to the soundboard, which amplifies them.

The piano is widely used in western music for solo performance, chamber music, and accompaniment. It is also very popular as an aid to composing and rehearsal. Although not portable, and often expensive, the piano's versatility and ubiquity has made it among the most familiar of musical instruments.

The word piano is a shortened form of the word pianoforte, which is seldom used except in formal language and derived from the original Italian name for the instrument, gravicèmbalo col piano e forte (literally harpsichord with soft and loud). This refers to the ability of the piano to produce notes at different volumes depending on the amount of force used to press the keys.
