The strings of the piano are struck by felt hammers when the keys are pressed down.  Small felt dampers are used to stop the strings vibrating when not required.  The strings are strung on a strong iron frame and a ‘soundboard’ amplifies the sound.  There are two kinds of pedal operated by the player’s feet  –  one disables the damper action so that the sound continues to resonate, while the other alters the position at which the hammers strike the strings, thereby softening the sound.


Electronic Keyboard

The keyboard has keys similar to those of a piano but its sound is generated purely by electronic means.  Keyboardskeyboard are available in a range of styles and sizes from a three-octave basic model to one matching the scope of an acoustic piano.  Sophisticated models with a variety of features have made keyboards popular with those who cannot afford the cost of a piano.
