Introduction

Piano is a name given to a musical instrument, it produces sound by striking steel strings with fabric hammers that allows the strings to vibrate continuously. These vibrations are transmitted through the bridges to the soundboard which amplifies them. The piano is mostly used in the western music for solo performances and is more familiar of musical instruments. The word piano is derived from the Italian name pianoforte. It was invented by the Italian named Bartolomeo Cristofori in the year 1700.

Soundboard

The soundboard consists of a sheet of wood; One thickness spruce and Special taper. It is a part of a musical instrument used to produce a sound. It is part of a string that transmits the vibration of the strings greatly increasing the loudness of sound over that of the string alone. Soundboards are made of wood though other materials have skin or plastic on instruments. Plate or belly are some of the unique sound boards. In a Grand piano the soundboard is a large horizontal plate at the bottom and in the Upright Piano the soundboard is a large vertical plate at the bottom.

Sound Board Of Piano

In the piano the function of the soundboard is to take up and repeat the vibratory motions of the strings. More than two hundred strings that constitute the tone generating element of the piano are stretched at high tensions over wooden bridges which are rigidly fastened to the surface of the soundboard. Within a small fraction of a second any motions of the strings are transmitted through the bridges to the sound board, which as it were, accepts them and faithfully reproduces them over its entire surface. These tiny complex motions originating at the strings are transmitted to the large body of air surrounding the front and back surface of the soundboard. The soundboard of the piano acts just as the parchment head of a drum or the thin sheet diaphragm of the receiver element in a telephone. In order to obtain these very remarkable effects of amplification, the soundboard of the piano must be constructed with exquisite skill. The pieces of spruce wood from which it is made are matched in such a way that the grain runs roughly parallel to the line of the great bridges upon which the strings rest.
