How Do Keyboards In A Piano Work?

Answer Question

1 Answer - Sort by: Date | Rating

    When the tuned strings of a keyboard are struck by hammer they make a sound. When a key is pressed on the keyboard, it causes the hammer to strike the appropriate string and subsequently raises the damper off so that it vibrates liberally. The hammer after striking the string bounces back and is trapped by a monitoring device. Vibration is maintained at a frequency, which is different for each and every note. The strings are pulled across "bridges". The "soundboard" has bridges mounted on it. The vibration, which is caused due to depressing a key, is transferred to the soundboard. Soundboard amplifies the sound. The soundboard is a large wood like substance, which performs as a loudspeaker.

    A piano has 88 keys. When you push a key down, the instrument inside provokes the hammer to go up or forward to beat the strings. The hammer actually is in the form of a spherical stick with a head which gives the impression of a real hammer. Do not worry; the hammer will not damage the piano because the head is covered with thick wool felt. Due to vibration of the string, a musical sound is produced. As the string is connected to the big soundboard, the sound is much more amplified than what a mere string would have produced.
