Neo-Bechstein
Neo-Bechstein or Bechstein-Siemens-Nernst-Flügel were a set of electric grand pianos that were primarily built by Walther Nernst in the 1930s. Improvising upon an electrical prototype by Oskar Vierling, the design was executed around 1922, and the first of the set was marketed in 1931 to critical acclaim. The mechanics of the piano were implemented by the C. Bechstein company and the valve electronics were created by Siemens & Halske. The design belonged to a newer generation of electric pianos that eliminated the presence of any sound board. Description Smaller than the dimensions of an ordinary grand piano, the Neo-Bechstein measured about in length and belonged to a newer generation of electric pianos that eliminated the presence of any sound board. Thinner and shorter strings were grouped into 18 clusters of 5 strings each. The clusters all converged towards a pickup followed by a membrane-less microphone. The oscillations were correspondingly transformed into elect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oskar Vierling
Oskar Walther Vierling (born 24 January 1904 in Straubing, died 1986) was a German physicist, inventor, entrepreneur and professor in high-frequency technology. Vierling was an important inventor and engineer of electronic and electro-acoustic instruments between the 1930s and 1950s. Life Oskar Vierling attended school in Regensburg, and graduated with the Obersekundareife. In 1925 he graduated as an engineer at the Technische Hochschule Nürnberg in Nuremberg in Nuremberg, and later attending the Telegrafen technische Reichsamt in Berlin. Vierling then took a position at the Heinrich Hertz Institute. Fritz Sennheiser was his student and joined him in the founding of the high-frequency institute of the University of Hannover. Vierling was married and had two sons. The children took over the kind of Vierling Group. Career In 1929, Vierling along with Walther Nernst, created the Neo-Bechstein Electric Grand piano design, that divided the strings into groups of five, wit ...

Electric Grand Piano
The electric grand piano is a stringed musical instrument played using a keyboard, in which the vibration of strings struck by hammers is converted by pickups into electrical signals, analogous to the electric guitar's electrification of the traditional guitar. Since electric amplification eliminates the need for a resonant chamber, electric grand pianos are smaller and lighter (around ), and consequently more portable, than acoustic pianos. Electric amplification also bypasses the difficulty of having to mic a conventional grand piano, and thus makes an electric grand easier to set up with a sound system. History Experimental efforts to electrify the grand piano began in the late 1920s with the Neo-Bechstein. In 1939, the first commercially available model, the RCA Storytone, was introduced. These instruments featured the traditional hammered-string mechanism with pickups instead of a soundboard. In subsequent decades, other instruments now referred to as electric pianos wer ...

Walther Nernst
Walther Hermann Nernst (; 25 June 1864 – 18 November 1941) was a German chemist known for his work in thermodynamics, physical chemistry, electrochemistry, and solid state physics. His formulation of the Nernst heat theorem helped pave the way for the third law of thermodynamics, for which he won the 1920 Nobel Prize in Chemistry. He is also known for developing the Nernst equation in 1887. Life and career Early years Nernst was born in Briesen in West Prussia (now Wąbrzeźno, Poland) to Gustav Nernst (1827–1888) and Ottilie Nerger (1833–1876). His father was a country judge. Nernst had three older sisters and one younger brother. His third sister died of cholera. Nernst went to elementary school at Graudenz. He studied physics and mathematics at the universities of Zürich, Berlin, Graz and Würzburg, where he received his doctorate 1887. In 1889, he finished his habilitation at University of Leipzig. Personal attributes It was said that Nernst was mechanically min ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siemens & Halske
Siemens & Halske AG (or Siemens-Halske) was a German electrical engineering company that later became part of Siemens. It was founded on 12 October 1847 as ''Telegraphen-Bauanstalt von Siemens & Halske'' by Werner von Siemens and Johann Georg Halske. The company, located in Berlin-Kreuzberg, specialised in manufacturing electrical telegraphs according to Charles Wheatstone's patent of 1837. In 1848, the company constructed one of the first European telegraph lines from Berlin to Frankfurt am Main. Siemens & Halske was not alone in the realm of electrical engineering. In 1887, Emil Rathenau had established ''Allgemeine Elektrizitäts-Gesellschaft'' (AEG), which became a long-time rival. In 1881, Siemens & Halske built the Gross-Lichterfelde Tramway, the world's first electric streetcar line, in the southwestern Lichterfelde suburb of Berlin, followed by the Mödling and Hinterbrühl Tram near Vienna, the first electrical interurban tram in Austria-Hungary. 1882 saw the open ...

Sound Board (music)
A sound board, or soundboard, is the surface of a string instrument that the strings vibrate against, usually via some sort of bridge. Pianos, guitars, banjos, and many other stringed instruments incorporate soundboards. The resonant properties of the sound board and the interior of the instrument greatly increase the loudness of the vibrating strings. "The soundboard is probably the most important element of a guitar in terms of its influence on the quality of the instrument's tone ."Sloane, Irving (1989). ''Classic Guitar Construction'', p.20. Bold Strummer. . "The sound board is the most important element in the guitar." The sound board operates by the principle of forced vibration. The string gently vibrates the board, and despite their differences in size and composition, makes the board vibrate at exactly the same frequency. This produces the same sound as the string alone, differing only in timbre. The string would produce the same amount of energy without the board p ...

Piano
The piano is a stringed keyboard instrument in which the strings are struck by wooden hammers that are coated with a softer material (modern hammers are covered with dense wool felt; some early pianos used leather). It is played using a keyboard, which is a row of keys (small levers) that the performer presses down or strikes with the fingers and thumbs of both hands to cause the hammers to strike the strings. It was invented in Italy by Bartolomeo Cristofori around the year 1700. Description The word "piano" is a shortened form of ''pianoforte'', the Italian term for the early 1700s versions of the instrument, which in turn derives from ''clavicembalo col piano e forte'' (key cimbalom with quiet and loud)Pollens (1995, 238) and '' fortepiano''. The Italian musical terms ''piano'' and ''forte'' indicate "soft" and "loud" respectively, in this context referring to the variations in volume (i.e., loudness) produced in response to a pianist's touch or pressure on the keys: the gr ...

Valve Amplifier
A valve amplifier or tube amplifier is a type of electronic amplifier that uses vacuum tubes to increase the amplitude or power of a signal. Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers in the 1960s and 1970s. Valve amplifiers can be used for applications such as guitar amplifiers, satellite transponders such as DirecTV and GPS, high quality stereo amplifiers, military applications (such as radar) and very high power radio and UHF television transmitters. History Origins Until the invention of the transistor in 1947, most practical high-frequency electronic amplifiers were made using thermionic valves. The simplest valve (named diode because it had two electrodes) was invented by John Ambrose Fleming while working for the Marconi Company in London in 1904. The diode conducted electricity in one direction only and was used as a radio detector and a rectifier. In 1906 Lee De Forest added a third e ...

Action (piano)
The piano action mechanism (also known as the key action mechanismPressing, Jeffrey Lynn, PhD (1946–2002), (1992''Synthesizer performance and real-time techniques'' p. 124. or simply the action) of a piano or other musical keyboard is the mechanical assembly which translates the depression of the keys into rapid motion of a hammer, which creates sound by striking the strings. Action can refer to that of a piano or other musical keyboards, including the electronic or digital stage piano and synthesizer, on which some models have "weighted keys", which simulate the touch and feel of an acoustic piano. The design of the key action mechanism determines the "weighted keys" feeling; by Tobias Matthay (1963), p. 91. that is, the feeling of the heaviness of the touch of the keys."A professional pianist is likely to care most about the piano's action, because that is what controls its responsiveness and relative lightness--or heaviness--of touch. Roughly speaking, a piano's action is ligh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
