Transcript of How a Piano is Made

The Story of a Piano
Raw Materials
Post Production
Wool felt is used for the dampers on a piano to quiet the strings.
Wood from forests in Europe and the US supply wood for a piano.
Maple (for casing)
Spruce (for soundboard)
Beech (for bridges)
Other Light Woods (for keys)

Iron (for iron plate)
Steel (for strings)
Copper (for bass strings)
Brass (for tuning pins)
Iron and Copper are mined from mountains and are melted together to create alloys including Steel and Brass.
White and Black Plastic (used for keys).
Oil extracted from the earth is refined in refineries to create plastic.
Engineer Creates a Design
There are many variations of pianos, so to begin production of a piano, a scale engineer creates a new design to improve upon this instrument.

Key improvements include the structure and stability of the piano over varying temperatures.
To ensure that no one steals the piano design, the government patents it.
The Government Patents the Design
To begin production of a piano, a market in which there is a demand for a piano is needed.
To build the factory, buy the raw materials, and pay the factory workers, capital is needed.
Glue is used for adhesion of the thin, long, bent pieces of wood that create the case of the piano and other parts like the bridges.
Glue is created by processing animal bone and tissue.
Wool felt is created by processing the wool sheered off a sheep into small fibers, and then gluing them together into a sheet.
Lacquer is used to give the piano a beautiful look and feel, and smooth out the wood casing.
Lacquer is created by making a solution of nitrocellulose and plasticizers.
Paint is created by making a solution of pigments, solvents, and resins.
Paint is used to cover the iron plate.
Iron Plate
The iron plate is created by pouring molten iron in sand molds and letting it cool down.
The soundboard is created out of spruce by air drying it and after, in the kiln.
Ribs are created from spruce to fit the underside of the soundboard to keep it in the proper curvature.
The bridges are created using beech and are fitted to the soundboard using glue.
Strings are produced out of steel and copper at a piano string mill.
Wood Case
Long, thin pieces of maple wood are bent and glued together to create the rim and case of the piano.

Lacquer is applied to the case.
Braces for the soundboard and iron plate are created out of spruce wood.
Tuning Pins
Tuning pins are created out of brass which is melted and put into a special form.
Keys are created out of light wood that is cut and dried. Hammers are also created out of wood and are attached to the keys.

Wool felt is attached to the hammers.
Putting it Together
1. The wooden parts are glued
together by workers.
2. The iron plate is fitted on top of the
3. The strings are strung and are
fastened using the brass tuning
The warehouses distribute the piano to different stores.
The demand in the market results in multiple purchases and earnings.
The piano is shipped to warehouses in multiple countries and cities.
The piano is advertised in magazines and other various places.
