Cassotto
A cassotto is a 'sound chamber' within some more expensive accordions that contains one or more reed blocks of the treble side of the instrument. The sound of a cassotto register is warmer, less sharp than that of a register with unenclosed reeds. Technology The cassotto enclosure works as a passive frequency filter, attenuating higher frequencies and reinforcing lower ones (resonance). Instruments with cassotto have a sound quality distinctly different from instruments without. Usually only some reed blocks are placed in the cassotto enclosure, typically for low reed sets 16' and/or 8'. The remaining treble reed blocks are mounted straight. The firm Öllerer built a diatonic instrument with cassotto without register switches and two 8' (M) reed sets. Making a cassotto for diatonic instruments is quite more difficult due to the different reed plate arrangement. For chromatic accordions, a cassotto does not perform equally in every tone. On piano keyboards, the reed plates for bl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accordion
Accordions (from 19th-century German language, German ', from '—"musical chord, concord of sounds") are a family of box-shaped musical instruments of the bellows-driven free reed aerophone type (producing sound as air flows past a Reed (mouthpiece), reed in a frame). The essential characteristic of the accordion is to combine in one instrument a melody section, also called the descant, diskant, usually on the right-hand keyboard, with an accompaniment or Basso continuo functionality on the left-hand. The musician normally plays the melody on buttons or keys on the right-hand side (referred to as the Musical keyboard, keyboard or sometimes the manual (music), ''manual''), and the accompaniment on Bass (sound), bass or pre-set Chord (music), chord buttons on the left-hand side. A person who plays the accordion is called an accordionist. The accordion belongs to the free-reed aerophone family. Other instruments in this family include the concertina, harmonica, and bandoneon.

Resonance
Resonance is a phenomenon that occurs when an object or system is subjected to an external force or vibration whose frequency matches a resonant frequency (or resonance frequency) of the system, defined as a frequency that generates a maximum amplitude response in the system. When this happens, the object or system absorbs energy from the external force and starts vibrating with a larger amplitude. Resonance can occur in various systems, such as mechanical, electrical, or acoustic systems, and it is often desirable in certain applications, such as musical instruments or radio receivers. However, resonance can also be detrimental, leading to excessive vibrations or even structural failure in some cases. All systems, including molecular systems and particles, tend to vibrate at a natural frequency depending upon their structure; when there is very little damping this frequency is approximately equal to, but slightly above, the resonant frequency. When an Oscillation, oscillat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hohner
Hohner Musikinstrumente GmbH & Co. KG is a German manufacturer of musical instruments, founded in 1857 by Matthias Hohner (1833–1902). It is a subsidiary of Matth. Hohner AG. The roots of the Hohner firm are in Trossingen, Baden-Württemberg. Hohner has manufactured a wide range of instruments, such as harmonicas, kazoos, accordions, recorder flutes, melodicas, banjos, electric, acoustic, resonator and classical guitars, basses, mandolins and ukuleles (under the brand name ''Lanikai''). Hohner is known mostly for its harmonicas. From the 1940s through 1990s, the company also manufactured various electric/electronic keyboards. Especially in the 1960s and 1990s, they manufactured a range of innovative and popular electromechanical keyboard instruments; the cembalet, pianet, basset, guitaret, and clavinet. In the 1980s, several Casio synthesizers (such as the Casio HT-3000/Hohner KS61midi and the VZ-1/HS-2) were sold under the Hohner brand. Nowadays, Hohner produces h ...

Klingenthal
Klingenthal is a town in the Vogtland region, in Saxony, south-eastern Germany. Geography Klingenthal is situated directly on the border with the Czech Republic opposite the Czech town of Kraslice. Klingenthal is 29 km southeast of Plauen, and 33 km northwest of Karlovy Vary. It is part of the Musikwinkel, a historical center of musical instrument manufacturing. The Aschberg ("cinder mountain") towers above the town at 936 m. The extremely elongated town, 10.5 km from end to end, is surrounded by numerous woods of firs. The town is bisected by the Brunndöbra and Svatava (river), Svatava rivers. The two rivers unite at the Czech-German border to form the Svatava river, which in turn flows into the Ohře river at Sokolov, Czech Republic. History In 1591, Sebastian Köppel established a hammer mill near the border to Bohemia on the banks of the Svatava (river), Zwota in order to capitalize on the rich deposits of iron ore and the region's vast supplies of w ...

VEB Klingenthaler Harmonikawerke
VEB Klingenthaler Harmonikawerke (KHW) was a Volkseigener Betrieb, state-owned company based in Klingenthal, Saxony, and was the main producer of accordions, harmonicas, and electronic instruments in GDR, East Germany. History VEB Klingenthaler Harmonikawerke was established on 1 January 1949 through the consolidation of several private enterprises (F. A. Rauner, for example). 125,578 accordions were produced there in 1961 alone, which were exported to more than 40 countries. In 1964 VEB Vermona was incorporated into Klingenthaler Harmonikawerke. In 1972 a further 17 companies with state holdings were converted into state-owned companies and incorporated into VEB Klingenthaler Harmonikawerke (for example F. A. Böhm). The production and development of electronic instruments and effects pedals occurred in the factory at Schöneck, where the VERMONA logo first appeared on the ET-6 organ in 1972. In 1985 more than 3,000 people worked in the various sections. In 1990, during German r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overtones
An overtone is any resonant frequency above the fundamental frequency of a sound. (An overtone may or may not be a harmonic) In other words, overtones are all pitches higher than the lowest pitch within an individual sound; the fundamental is the lowest pitch. While the fundamental is usually heard most prominently, overtones are actually present in any pitch except a true sine wave. The relative volume or amplitude of various overtone partials is one of the key identifying features of timbre, or the individual characteristic of a sound. Using the model of Fourier analysis, the fundamental and the overtones together are called partials. Harmonics, or more precisely, harmonic partials, are partials whose frequencies are numerical integer multiples of the fundamental (including the fundamental, which is 1 times itself). These overlapping terms are variously used when discussing the acoustic behavior of musical instruments. Alexander J. Ellis (translating Hermann von Helmholtz) ...

Frequencies
Frequency is the number of occurrences of a repeating event per unit of time. Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio signals (sound), radio waves, and light. The interval of time between events is called the period. It is the reciprocal of the frequency. For example, if a heart beats at a frequency of 120 times per minute (2 hertz), its period is one half of a second. Special definitions of frequency are used in certain contexts, such as the angular frequency in rotational or cyclical properties, when the rate of angular progress is measured. Spatial frequency is defined for properties that vary or cccur repeatedly in geometry or space. The unit of measurement of frequency in the International System of Units (SI) is the hertz, having the symbol Hz.
