"The piano is the most important instrument ever invented; its importance to the music, as printing is to poetry." Famous writer George Bernard Shaw said.
In all kinds of musical instruments, a piano is a machine that needed hand operation.
With the meeting and combination of man and machine, it was suddenly informed!
Playing Beethoven's music, powerful arguments such as the philosopher's contemplation;
Play the Chopin such as poetry; playing Debussy, painter.
It had features of poet, painter, philosopher and motivator.
Nietzsche, Tolstoy, Gretel love it and play,
Not without reason, of course.
在意大利佛罗伦萨的羽管键琴制造师克里斯托弗利在自己的工作室里，改进创新设计了琴键带动琴槌击弦的机械结构，这种结构的击弦机，用不同的力度敲击琴键，使钢琴可以发出明显的强弱变化，命名为Gravicembalo col Piano e forte，后来简称为piano forte;并且先后在法国和德国逐渐被运用和发展。
In 1709, Christopher Lee, a harpsichord maker, had designed a new mechanical structure of the hammer hitting the action led by key-board in his studio of Florence, Italy. The piano could sound significantly by the action hitting the key-board in the different strength. It named Gravicembalo colPiano e forte, and later referred to as the piano forte; and had gradually been applied and developed in France and Germany.
In 1711, Yo Seu, a British trumpeter and lutenist, had invented the fork. Fork had been in use for centuries as an important acoustic instrument and tuning tool.
In 1716, Taylor, a British mathematician, had deduced a very important formula to calculate the frequency of the strings; by that formula, it had been concluded that frequency of the strings depended on chord, quality and tension. Thus had been the foundation for design of the late piano strings.
In 1725, Gottfried Silber Mann, a Germany famous organ maker, made Germany the first mallet-piano (Hammerklavier).
In 1729, serving in the Thomas Church in Leipzig organ masters, choir conductor, John Sebbas Bach pointed out that the piano's high-pitched voice of weak defects and uncomfortable playing feel. Through further efforts and improvement, the work of the organ-maker Silber Mann had gained the approval and accreditation of Bach followed development of piano manufacturing center moved to Germany.
In 1742, Johann Socher, in Sonthofen of Germany, had made a most ancient square (also called a table) piano which was known till now, before that there were just harpsichord and transformed clavichord.
In 1745, in Gerhard City of Germany, Friedrich had put his idea into reality-to place the piano upright to save space; and manufactured one piano that can be placed upright, similar to the Grand Piano, called Pyramide(pyramid shaped); then after that many similar designs were utilized by many piano manufacturers, but the distance also was still far from our current upright piano.
A few years later Friedrich started mass production of square pianos, known as "fortbien".
In 1753, in The Play on the Keyboard Instruments, published by Carl Philip Emmanuel Bach, though the clavichord was still preferred, but at the same time also there was no lack of praise for new piano. Emmanuel Bach also became the founder and pioneer of piano music. Since then, in this area of music, Mozart, Haydn and Beethoven, and other famous musicians appeared.
In 1767, in several decades in the United Kingdom the square piano had been developed and improved, and square piano as accompaniment during this period, had firstly appeared on the concert stage.
In 1768, John Christian Bach Piano led square piano as a solo instrument into the concert hall, called the "London Bach". Until 1770, composers had not focused on "new piano" Hammerklavier, pianoforte, and they still wrote for subject the harpsichord (Cembalo) the music or there was also for"new piano". Bach's sons Emmanuel and Christian Bach took the lead in the development of playing music with distinct piano style and performance skills. After that Haydn, Mozart, and Andreas Clementi Andreas Clementi had been the piano makers.
In 1770, John Andrea r .Stein, a piano maker in Germany Augsburg had developed new striking machine-place string drumsticks on the key levers (Prellmechanik). This simple "break even" form was also known as "Viennese action piano", this instrument technology based on the Vienna classical piano music had played an important role. The piano production with this type of action had been continued into the 19th century.
In 1772, from 1772 to 1777, Bai Keer and Standart, two British, had perfected action system to become British-style action, which was the predecessor and foundation of the modern Grand Piano Action.
In 1774, Joseph Merlin, a British, had developed Una-Corda, a mobile pedal device, so that the hammer can reach the single string to make the piano may sound weakened. In this period it was the knee pedal, which was controlled by the knee pedal. Until now it was developed to modern pedal.
In 1778, the arrangement design for wires and striking location of the piano had been firstly systematized by Baldwin from United Kingdom, which was the first one to be determined on the basis of science in this field.
In 1790, Erhard in Paris had manufactured the three-stringed piano treble, the Alto field each sound corresponds to three strings.
In 1793, Broadwood piano factory of Bach family from United Kingdom with nearly two generations had made the last harpsichord; about ten years ago, Baldwin had sold 38 harpsichords and 133 hammerklaviers. Two years after Mozart died, Beethoven was just 23 years old, but still played with the harpsichord.
In 1794, Ybahhe from Germany had built his first square piano and created the oldest piano factory which still existed now.
In 1808, Sebastian Erhard, a French piano maker, had invented the "simple fracture" devices of the grand piano, what we called complex leveraged piano action. Today, the grand piano's action was still made in accordance with this principle.
In 1811, Robert Vorm of London had built his Cottage piano, very close to the modern upright piano, with height of 167 cm. It was the forerunner of the modern upright piano.
In 1817, Broadwood, a British, his factory had presented Beethoven a piano, when Beethoven was deaf already.
In 1823, there had been 85 key-boards for piano, in this range, from contra A to four-lined octave a, had been set as a standard.
In 1825, Barkh had used iron skeletal structure for his square piano and made it more solid.
In 1826, Papae from France had changed the traditional cortex of piano hammer using blanket hammer, and the blankets were woven blankets at that time. Then the hammer factory was built, and the whole sound processes were born in the late manufacturing process of piano.
In 1826, Vorm had improved his action system for his upright piano; and modern upright piano was invented at that moment which was used until now.
In 1828, Schubert was gone; at the same year, Modell Senator piano factory was established in Vienna.
In 1834, Webster had produced the first cast steel string, changing the previous iron strings and brass strings, contributing to the perfect chords of the piano manufacturing.
In 1840, Haierzi in Paris, had improved the triangle piano striking machine once again, which had been still in used until now.
SILVIA PIANO(西尔维娅钢琴) 推出自动演奏钢琴，走在当时科技前沿。
In 1882, SILVIA PIANO had introduced the automatic performance piano which was at the frontiers of the science.
In 19th century, the piano manufacturing industry was heat, there had been many famous piano manufacturing families and their brands even last so far, before the World WarⅡ, there were hundreds of Germany piano manufacturing families, and after the World WarⅡto the present, the piano companies and brands which still exist so far were listed as following. But some companies had been bought by companies in Asia.
