Stradivarius
A Stradivarius is one of the string instruments, such as violins, violas, cellos, and guitars, crafted by members of the Stradivari family, particularly Antonio Stradivari (Latin: Antonius Stradivarius), in Cremona, Italy, during the late 17th and early 18th centuries. These instruments are known for their craftsmanship, tonal quality, and lasting legacy, and are considered some of the finest ever made. Stradivari's violins, in particular, are coveted by musicians and collectors, with many selling for millions of dollars. Antonio Stradivari made over 1,100 instruments, with approximately 650 surviving today. The exact methods Stradivari used to produce the instruments' famed sound remain unknown, with theories ranging from the unique quality of the wood used during the Little Ice Age to the varnishes and chemical treatments applied. Despite extensive scientific research, including modern acoustic analysis and CT scans, no one has been able to conclusively replicate or fully expl ...

Stradivari Family
Antonio Stradivari (, also , ; – 18 December 1737) was an Italian luthier and a craftsman of string instrument In musical instrument classification, string instruments, or chordophones, are musical instruments that produce sound from vibrating strings when a performer strums, plucks, strikes or sounds the strings in varying manners. Musicians play some ...s such as violins, cellos, guitars, violas and harps. The Latinisation of names, Latinized form of his surname, ''Stradivarius'', as well as the colloquial ''Strad'' are terms often used to refer to his instruments. It is estimated that Stradivari produced 1,116 instruments, of which 960 were violins. Around 650 instruments survive, including 450 to 512 violins. His instruments are considered some of the finest ever made, and are extremely valuable collector's items.

Jean-Baptiste Vuillaume
Jean-Baptiste Vuillaume (; 7 October 1798 – 19 March 1875) was a French luthier, businessman, inventor and winner of many awards. He was one of the finest French luthiers of the 19th century and a key figure in the world of violin making. His workshop made more than 3,000 instruments. His vision was the ethics and beauty of the Cremona school. Early life Vuillaume was born in Mirecourt, where his father and grandfather were luthiers. His father taught him the basics of violin making. Career Vuillaume moved to Paris in 1818 to work for François Chanot. In 1821, he joined the workshop of Simon Lété, François-Louis Pique's son-in-law, at Rue Pavée St. Sauveur. His first labels are dated 1823. Lété and Vuillaume became partners and in 1825 settled in the Rue Croix-des-Petits-Champs under the name of "Lété et Vuillaume". In 1827, at the height of the Neo-Gothic period, he started to make imitations of old instruments, some of which were identical to the origi ...

Cellos
The violoncello ( , ), commonly abbreviated as cello ( ), is a middle pitched bowed (sometimes plucked and occasionally hit) string instrument of the violin family. Its four strings are usually tuned in perfect fifths: from low to high, C2, G2, D3 and A3. The viola's four strings are each an octave higher. Music for the cello is generally written in the bass clef; the tenor clef and treble clef are used for higher-range passages. Played by a '' cellist'' or ''violoncellist'', it enjoys a large solo repertoire with and without accompaniment, as well as numerous concerti. As a solo instrument, the cello uses its whole range, from bass to soprano, and in chamber music, such as string quartets and the orchestra's string section, it often plays the bass part, where it may be reinforced an octave lower by the double basses. Figured bass music of the Baroque era typically assumes a cello, viola da gamba or bassoon as part of the basso continuo group alongside chord ...

Museo Del Violino
The Violin Museum (), formerly the Stradivarius Museum (Italian: Museo Stradivari), is a musical instrument museum located in Cremona. The museum is best known for its collection of stringed instruments that includes violins, violas, cellos, and double basses crafted by renowned luthiers, including Antonio Stradivari and Giuseppe Guarneri del Gesù. History At the time of his death in 1883, Enrico Ceruti, a prolific and successful Italian luthier and musician in his own right, passed down the objects from his workshop to Michelina, the widow of his son, Paolo. Michelina was at that time, married the second time to Giovanni Battista Cerani, who was also a close friend of Enrico Ceruti. Cerani was an instrument dealer and collector, who later donated various musical instruments and models owned by great Cremonese violin luthiers, including Antonio Stradivari to the town of Cremona in 1893, and thus, the Stradivarius Museum () was established. The museum was later enriched by the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Violins
The violin, sometimes referred to as a fiddle, is a wooden chordophone, and is the smallest, and thus highest-pitched instrument (soprano) in regular use in the violin family. Smaller violin-type instruments exist, including the violino piccolo and the pochette, but these are virtually unused. Most violins have a hollow wooden body, and commonly have four strings (sometimes five), usually tuned in perfect fifths with notes G3, D4, A4, E5, and are most commonly played by drawing a bow across the strings. The violin can also be played by plucking the strings with the fingers (pizzicato) and, in specialized cases, by striking the strings with the wooden side of the bow (col legno). Violins are important instruments in a wide variety of musical genres. They are most prominent in the Western classical tradition, both in ensembles (from chamber music to orchestras) and as solo instruments. Violins are also important in many varieties of folk music, including country music, bl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cremona
Cremona ( , , ; ; ) is a city and (municipality) in northern Italy, situated in Lombardy, on the left bank of the Po (river), Po river in the middle of the Po Valley. It is the capital of the province of Cremona and the seat of the local city and province governments. The city of Cremona is especially noted for its musical history and traditions, including some of the earliest and most renowned luthiers, such as Giuseppe Guarneri, Antonio Stradivari, Francesco Rugeri, Vincenzo Rugeri, and several members of the Amati family. History Ancient Celtic origin Cremona is first mentioned in history as a settlement of the Cenomani (Cisalpine Gaul), Cenomani, a Gauls, Gallic (Celtic) tribe that arrived in the Po River, Po valley around 400 BC. However, the name Cremona most likely dates back to earlier settlers and puzzled the ancients, who gave many fanciful interpretations. Roman military outpost In 218 BC the Ancient Rome, Romans established on that spot their first military outpos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Little Ice Age
The Little Ice Age (LIA) was a period of regional cooling, particularly pronounced in the North Atlantic region. It was not a true ice age of global extent. The term was introduced into scientific literature by François E. Matthes in 1939. Matthes described glaciers in the Sierra Nevada (U.S.), Sierra Nevada of California that he believed could not have survived the hypsithermal; his usage of "Little Ice Age" has been superseded by "Neoglaciation". The period has been conventionally defined as extending from the 16th to the 19th centuries, (noted in Grove 2004: 4). but some experts prefer an alternative time-span from about 1300 to about 1850. The NASA Earth Observatory notes three particularly cold intervals. One began about 1650, another about 1770, and the last in 1850, all of which were separated by intervals of slight warming. The Intergovernmental Panel on Climate Change IPCC Third Assessment Report, Third Assessment Report considered that the timing and the areas affecte ...

Simone Fernando Sacconi
Simone Fernando Sacconi (May 30, 1895 in Rome – June 26, 1973 in Point Lookout) was an expert Italian violin maker and restorer who studied fellow ''luthier'' Antonio Stradivari extensively during his lifetime. "While still at school he became a workshop assistant to Giuseppe Rossi, a pupil of Degani. By the time he was 16, Sacconi already had his own clientele, and a particular ability as a maker of copies. In 1931 he moved to New York to work for the dealer Emil Herrmann. He continued to make new instruments – and occasionally bows – but his time there was mainly taken up with repairs and restoration work. In this field he had no equal, an example of his work being a Stradivari of the best period, virtually destroyed in an accident in 1948, which now shows no sign of having suffered. In the imitation of old Italian varnish he excelled all rivals. In 1951, upon the invitation of Rembert Wurlitzer, Sacconi went with his pupil D’Attili to work for Rembert Wurlitzer Co. ...

Woodworm
A woodworm is the Xylophagy, wood-eating larva of many species of beetle. It is also a generic description given to the infestation of a wooden item (normally part of a dwelling or the furniture in it) by these larvae. Types of woodworm Woodboring beetles with larvae commonly known as woodworm include: *Ambrosia beetles (weevils of the subfamilies Scolytinae and Platypodinae) *Woodboring weevils (''Pentarthrum huttoni'' and ''Euophryum confine'') *Ernobius mollis, Bark borer beetle or waney edge borer (''Ernobius mollis'') *Common furniture beetle (''Anobium punctatum'') *Deathwatch beetle (''Xestobium rufovillosum'') *hylotrupes, House longhorn beetle (''Hylotrupes bajulus'') *Lyctus brunneus, Powderpost beetle (''Lyctus brunneus'') *Wharf borer (''Narcerdes melanura'') Manifestation Signs of woodworm usually consist of holes in the wooden item, with live infestations showing powder (faeces), known as frass, around the holes. The size of the holes varies, but they are typic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potassium Silicate
Potassium silicate is the name for a family of inorganic compounds. The most common potassium silicate has the formula K2SiO3, samples of which contain varying amounts of water. These are white solids or colorless solutions.Gerard Lagaly, Werner Tufar, A. Minihan, A. Lovell "Silicates" in Ullmann's Encyclopedia of Industrial Chemistry, Wiley-VCH, 2005. Synthesis, structure, reactions Potassium silicate can be synthesized in the laboratory by treating silica with potassium hydroxide, according to this idealized equation: : These solutions are highly alkaline. Addition of acids causes the reformation of silica. K2SiO3 adopts a chain or cyclic structures with interlinked monomers. Each Si is tetrahedral. Uses Woodwork protection against fire Impregnation of wood with a potassium silicate solution is an easy and low-cost way for rendering the woodwork of houses secure against catching fire. The woodwork is first saturated with a diluted and nearly neutral solution of potash si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
