In 17 1 1 year, Italian writer Scipione Maffei wrote an article introducing this new instrument, including an inaccurate mechanism diagram. This article is widely circulated in western Europe, and many craftsmen make pianos accordingly. 1726, German organ manufacturer Gottfried Silbermann (1683-1753) also made a piano according to this article, adding a manual damper similar to the damper pedal of a modern piano, which can raise the damper on the strings. /kloc-in the 1970s, Hilberman introduced his piano to Bach, but Bach didn't like it at that time, complaining that the treble was too weak and the dynamic range was not wide. Later, Hilbert improved it, and Bach visited Berlin in 1747 to try and praise Hilbert's piano. There are many students in Hilberman who have made great contributions to the early piano development. Among them, 12 students are called "Twelve Disciples". Some people immigrated to Britain and gradually formed two different manufacturing schools, German-speaking countries and Britain.
Vienna-style string striking machine
/kloc-In the late 8th century, more and more pianos were made. John Andreas Stein (1728- 1792), a student of Sherberman, began to make pianos in augsburg. Stein piano has a backward hammer, which is very sensitive to the touch of keys compared with modern piano. Mozart visited augsburg in 1777 and tried Stein's piano (at that time, Stein's piano cancelled the escapement of Christopher's piano). Later, in a letter to his father, Mozart praised Stein's piano for its balanced sound quality and exquisite manufacturing technology, but also pointed out the shortcomings of the escapement mechanism. Stein later improved, invented the Prellmechanik string beater, added the escapement mechanism and perfected the sustain pedal. Stein's daughter Nannette Streicher and her son-in-law Johann Andreas Streicher continue their piano manufacturing business in Vienna. They are friends of Beethoven, who owns a Streicher piano. At the same time, there are other piano manufacturers in Vienna, including Anton Walter, whose piano is louder than Streicher's. Walter is a friend of Mozart, who bought a Walter piano at 178 1. There is Conrad Graf (1782- 185 1), who made Beethoven's last piano and opened the first piano manufacturing enterprise in Vienna. These pianos developed in German-speaking countries are called Vienna-style clavichords. Besides grand piano, there are Viennese-style clavichords and square pianos. The Vienna-style percussion piano uses a wooden frame, each tone has two strings, and the hammer is wrapped in leather. The colors of white keys and black keys of keys are contrary to those of modern pianos, with weaker sound, clearer contrast and shorter reverberation time.
English string striking machine
Since 1760, due to the German Seven-Year War, many students in Hilberman moved to England, among which Johann Christoph Zumpe began to make cheap square pianos in the workshop of Burckardt Shudi, a harpsichord manufacturer. Although this kind of square piano has no escapement mechanism and its technology is relatively backward, it is very popular and plays an important role in the process of piano replacing harpsichord. 1768, J.C. Bach made the first public performance in piano history with this square piano. Americus Backers, a Dutchman, and Broadwood and Robert Stodart, two mechanics in Shudi Workshop (both students of Hilberman) invented a more advanced string striking machine, adding escapement and check mechanism, which made the sound deeper and deeper, but reduced the sensitivity of touching keys and required deeper touching keys. This kind of string striking machine is called English string striking machine or Broadwood string striking machine. The British percussion piano looks like a harpsichord, with three strings for each sound. 1769, Broadwood married Barbara Shudi, the daughter of Master Shudi, and later took over Shudi's workshop and changed her surname (which still exists today). The piano she made was once shipped to Beethoven.
Sliding soft system technology
Slide soft system technology, referred to as 3S technology for short, is the best innovation in upright piano, which was invented by Toyo Piano Manufacturing Company. Up to now, ordinary upright piano has weakened the sound of the piano by changing the striking distance and striking the strings. The piano using 3S technology adopts the same working principle as grand piano, reducing the number of strings to achieve the effect of weak sound. 3S technology can make the effective plucking speed reach 1.5 times that of ordinary pianos, and it can be played at a plucking speed not lower than that of grand piano. And when playing with a weak pedal, the speed of combo will not be affected at all. Even if upright piano installed with 3S technology steps on the mute pedal, the touch of the keys will not change. Ordinary upright pianos will inevitably feel bad when playing weak notes, but 3S series pianos overcome this problem. It achieves the effect of weak sound by hitting two of the three strings, one of the two strings and one of the strings with one end of the hammer. It can not only reduce the volume, but also freely change the timbre, so that you can enjoy the playing effect not inferior to that of grand piano. At present, only Apollo pianos produced by Toyo Piano Manufacturing Company have 3S technology in upright piano.
