* Piano keys: The pianoforte has a set of keys, which are pressed to produce sound. Each key is connected to a hammer that strikes a string. The strings are stretched across a metal frame and are tuned to different pitches.
* Hammers: The hammers of a pianoforte are made of felt and are attached to a wooden rail. When a key is pressed, the rail moves forward and the hammers strike the strings. The hammers bounce back after striking the strings, allowing them to vibrate freely.
* Strings: The strings of a pianoforte are made of metal and are stretched across a metal frame. The strings are tuned to different pitches and produce sound when they are struck by the hammers.
* Resonance board: The resonance board of a pianoforte is a large, flat piece of wood that is attached to the back of the instrument. The resonance board helps to amplify the sound of the strings and give the piano its characteristic tone.
* Dampers: The dampers of a pianoforte are small pieces of felt that are attached to the hammers. When a key is released, the dampers fall onto the strings and stop them from vibrating.
* Pedals: The pedals of a pianoforte are located at the bottom of the instrument. The pedals control the sound of the piano by changing the way the hammers strike the strings.
