88 Key Weighted Piano keyboard Story

The beginning of 88 Key Weighted keyboard

It was at the end of the 17th century when, at the court of the Medici in Florence, a certain Bartolomeo Cristofori invented the ancestors of what today are known as the grand pianos. He took into account the desire to make the dynamics (loud and quiet sound) audible by the strength of the keystroke. However what sounds so simple, was a small technical revolution, in contrast to the harpsichord. Where the strings are plucked for sound production. In such an instrument a dynamic soft/loud sound could not be achieved.

New Instrument needed a new Name

The new instrument required a complicated mechanism in which the strings were struck with small leathered hammers. This revolutionary instrument was first known as gravicembalo col piano e forte (Heavy Harpsichord with Soft and Loud). At a later date it was shortened to the Piano Forte (Soft, Loud). And finally it has become more commonly known as a Piano.

In the next one hundred and fifty years, after its invention, the mechanics and design of the piano  were refined up until in the second half of the 19th century. This marked a watershed of piano refinement and pianos have been built to this format ever since.

All modern pianos still use the basic design of piano as established over 150 years ago the mechanics and materials used are still very much the same. Small developments have been made over the years. Those that truly break new ground are retained and those that don’t are discarded.




The most important stages were:

    • 1820 – With the development of the first pianino (cottage piano) – ie an upright instrument. Robert Wornum gradually replaced the design of the board piano.
    • 1821 – Sebastien Erard develops the wing repetition mechanism that allows a much faster and more controlled keyboard.
    • 1826 – Henri Pape uses felt instead of leather as material for the hammer heads, the tone generated in the instrument was better.
    • 1826 – Robert Wornum improves the mechanics of his pianino and creates the basis of the keyboard instrument. The most upright piano ever built to this day.
    • 1840 – or there about, Henri Herz once again improves the wing mechanics of Erard (double repetition mechanics).
    • 1855 – Steinway in New York builds the first wing with a cross-string covering. The strings no longer ran parallel but intersected, in combination with a cast-iron frame.
    • 1866 – Carl Rönisch invents the full armour plate. A cast plate covers the post and thus provides greater stability and rigidity.

The Wonderful Modern Piano

All of these developments were a response to the the pianists and musicians. Who at the time demanded an instruments with a wider range and stronger tones.

Since that time, there have been many minor and some major innovations in the piano or grand piano design. But in essence, the instruments built today were invented and establish during the mid 19th century.

Interesting facts about pianos

  • pinoa strings and hammersInvented some 200 years ago, in Italy. Based on the harpsichord, they differed in that a hammer struck the string where’s the harpsichord plucked the string.
  • Incidentally the harpsichord was based on the harp.
  • That change in how the note was produced resulted in a completely different instrument, which could be played loud or soft, hence its name piano forte. Which means soft loud, in Italian.
  • Contrast that with the harpsichord which can only play at one level as the string is either plucked out it isn’t. There’s no in-between.
  • Pianos have strings and each string has to be tuned. An intricate arrangement of pegs hold a strings under tension. These steel strings are held under huge force and the purpose is the keep the strings in tune.
  • Despite that force, pianos do need regular tuning. A new piano needs to be tuned 3 or 4 times a year. As they get older twice a year will normally suffice.
  • piano synthesizerAlthough made with extreme precision, the main material is wood. So the tuning of the instrument is affected by atmospheric conditions. Damp and humidity are the main culprits here, causing the piano to go out of tune.
  • The two main types of piano are the grand piano and the upright piano. The trade off is between size versus quality of sound. And although the baby grand piano is a compromise on the full size grand, it’s still rather large and not everyone has room for these.
  • Grand pianos are also faster, which means the keys reset when half way up.on an upright the key has to fully return before it can be pressed again.
  • Modern electronic pianos arrived in the 80s. These proved very popular and the sound has improved and before richer over the years. But one of the truly amazing qualities of these electronic instruments, is that their sound can be altered and they can reproduce the sound of any of the famous models of grand pianos out there.

Instruments with a Keyboard

In the world of keyboards everyone knows the piano and its derivatives, grand piano, upright piano. But we thought it would be fun to look at other instruments that also have keyboards.

Starting with the mechanical keyboards


The world comes from the french word meaning “heavenly”. It sound is similar to a glockenspiel but softer and more refined. It looks like an upright piano with four octaves. Hammers, operated by the keys, strike metal plates to give that heavenly sound.


These instruments were small in size, compared to pianos and so weren’t very loud. The sound is produced by blades striking iron or brass strings. Very popular in the 16th,17th and 18th centuries



Looking much like a piano, the harpsichord plucks rather that strike the string. Which means that unlike a piano where the pianist can play both loud and softer sounds, the harpsichord, plays with one intensity, no matter how hard one strikes the key.


This a small organ where the player operates foot pedals to pump air through the instrument. Thin metal reeds produce the sound via a keyboard, which controls the airflow.


A hand held instrument, the accordion comprises of a set of bellows which blow air over a set of metal reeds which vibrate. The player flexes the instrument which generates the sound. The keyboard down one side plays the melody, the buttons on the other side plays the base.


These use a keyboard as electronic switches. The switching is processed using microprocessors and converted into sound through a speaker, or recorded by electronic means.

Sounds or samples can be altered so that many variations are possible. Synths can mimic other instruments or natural sounds, such as whale song. Alternatively completely new sounds can be invented and played through the synth.
