What is a Piano?

Piano is a keyboard musical instrument. The word piano is the shortened form of pianoforte. The name comes from the fact that the instrument could be played softly(piano) or loudly(forte).

Piano’s wooden body encloses the metal strings, hammers and the soundboard. Different pitches are produced by pressing the keys on the piano which moves the hammers inside to strike the strings.
Sound Board
In a string instrument, the strings vibrate against a surface which is called sound board. The resonant properties of the sound board increase the loudness greatly.
Cast Iron Plate
Cast iron plate or cast iron frame sits on top of the sound board and serves as a barrier which sustains the massive tension of the strings.
Hammers
Hammers are inside the piano. They hit the strings and make sound when the keys are pressed down. Once the key is pressed down hammer hits the string quickly and bounces off to let the string vibrates and produces the sound, when the key is released damper falls back on to the string and stops the string’s vibration and the sound stops.
Treble Strings
Treble strings are the strings that produce the high sounds and play the high notes
Bass Strings
Bass strings are the strings that make the low sounds and play the low sounds.
Action Frame
Action frame is a frame that attached all of the playing mechanism into the piano. It holds the various playing parts together so they can work properly.
Keyboard
Keyboard is a set of adjacent depressible keys on the piano. Pressing these keys moves the hammers to hit the strings and to make sounds.
Tuning Pins
Tuning pins are the pins that hold the strings in tune.
