Piano parts

The word piano comes from the Italian pianoforte, which alludes to that instrument made up of keys that push strings to create a certain sound. By pressing each key strategically and repetitively, it is possible to obtain the sound, which can be modified with the use of the piano pedals.


It is made up of a sound box, which has an integrated keyboard where the strings are played with felt-lined hammers, thus generating the sound. These ropes are made on a steel basis.

Piano parts

Harmonic table

It is in charge of amplifying the sound waves that the strings create when vibrating, this box being the main element that creates the resonance in the piano. This is located under the ropes and parallel to them.

It is made on the basis of wood sheets, where fir is mainly used, where pieces of 10 cm width and 8 mm thickness are taken. These sheets are glued from the side, maintaining the same direction as the veins.

Its center has a convex shape, which helps resonance.

Percussion mechanism

It is a group of pieces and levers in charge of bringing the hammer to the keys, thus creating the vibration and sound on the piano.


These are attached in a crossed way to the harmonic table where they come to guarantee the stability of tension and the curvature of the interior of the wood of the table. These are glued perpendicular to the veins, which helps the resonances to spread in all directions.


It is usually known as an iron plate or frame. It is the backbone of this instrument, responsible for sustaining the tension of the strings, which has between 15 and 20 tons.

The frame is made with a piece of iron, which gives firmness and reliability to the structure. In turn, it has a varnish finish and a bronze coating.


The keyboard is made up of 88 keys, with the exception of the Bossendorfer that has 96 keys. It is made from beech, linden or fir wood.


Some keys have lead cylinders, such as the bass register keys.


It is in this part where the strings are tensioned, this being the area where the vibratory energy produced by the strings is transmitted to the soundboard. This bridge is divided into two parts: one area for the record region and the other for the rest.


It is in this part of the piano that the tuning pegs are inserted. It is made on the basis of solid wood sheets, where commonly beech sheets are placed one on top of the other.

They are shown with small metal cylinders where the ropes are hooked, which are placed with a very slight 10 degree tilt.


This is the piece of furniture that can be seen from the outside of the piano, which prolongs the function of the soundboard much more. It uses a bar made up of large wooden bars that serve as reinforcement and that manage to support the frame. Below this are the pedals.


Also called top table. It is the part of the piano that closes the cabinet and at the same time is used to direct the music towards the public. This usually has different heights, which allows you to play with the sound, where a greater or lesser sound is heard depending on its height.


These strings are placed in a fan, which are opened covering the area from the headstock towards the bridge, with this it is possible to amplify the sound of the instrument much more.

There are 224 strings in total, which are subjected to a tension of approximately 75 kg, with which proper tuning is achieved. These are made of hard carbon steel.


It is located under the box, where you can find three types of grand pianos, these are:

  • Tonal Penalty : Also known as a central pedal. It simultaneously lifts the strings below when the pedal is operated.
  • Resonance pedal : also called a forte pedal or a right pedal. With this pedal it is possible to simultaneously raise each of the dampers, where you get to get a free resonance of the strings.
  • Light blue pedal : it is usually named as the right pedal. With this, the hammers can be moved laterally.
