The piano is a musical instrument played by means of a keyboard that proces sound by striking steel strings with felt hammers. The hammers immediately rebound allowing the strings to continue vibrating at their resonant frequency. These vibrations are transmitted through a bridge to a soundboard that amplifies them.
The piano is widely used in Western music for solo performance, ensemble use, 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 have made it one of the most familiar musical instruments. It is sometimes classified as both a percussion and a stringed instrument. According to the Hornbostel-Sachs method of music classification, it is grouped with Chordophones.
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, clavicembalo [or gravicembalo] col piano e forte (literally harpsichord with soft and loud). This refers to the instrument's responsiveness to keyboard touch, which allows the pianist to proce notes at different dynamic levels by controlling the speed with which the hammers hit the strings.
A musical instrument is a device constructed or modified with the purpose of making music. In principle anything that, proces sound, and can somehow be controlled by a person playing it, can serve as a musical instrument. The expression, however, is reserved generally for items that have a specific musical purpose. The academic study of musical instruments is called organology.
Voice, that is, the human voice, is an instrument in its own right. A singer generates sounds when airflow from the lungs sets the vocal cords into oscillation. The fundamental frequency is controlled by the tension of the vocal cords and the tone quality by the formation of the vocal tract; a wide range of sounds can be created.

String instruments generate a sound when the string is plucked, strummed, slapped, etc. The frequency of the wave generated (and therefore the note proced) usually depends on the length of the vibrating portion of the string, its linear density (mass per unit length of string), the tension of each string and the point at which the string is excited; the tone quality varies with the construction of the resonating cavity. Examples: guitars, violins and sitars.
乐器是一个设备建造或与制作音乐的目的，修改。原则上任何事情，产生声音，并能以某种方式由一个人玩的，可以作为一种乐器控制。的表达，然而，保留的项目一般有特定的音乐宗旨。在乐器被称为颅相学的学术研究。
声音，即人类的声音，是在它自己的权利的工具。一个歌手的声音时产生的气流从肺部套到声带振动。控制的基本频率是由声带紧张和由声道音质的形成，一个范围广泛的声音可以被创建。
弦乐器生成一个字符串时，弹拨声，strummed，打耳光，等产生的波的频率（因此产生的说明）通常对字符串的振动部分的长度而定，其线性密度（每单位质量字符串的长度），每个字符串紧张和点是在哪个字符串兴奋;不同的音质与共鸣腔的建设。例子：吉他，小提琴和西塔。
