The History of the Euphonium Euphonium Though Sommers of Weimar is credited with inventing the Euphonium circa , this instrument represents the culmination of earlier experiments dating back as far as circa Like the tuba, the euphonium is an instrument possessed of great range- about four full octaves in the hands of a player capable of making full use of its attributes. Some consider the euphonium to be a B flat tenor tuba; others claim it to be a tenor or baritone Fluegelhorn; still others have mistakenly claimed that the euphonium was a Sax invention, or a derivation of a Sax instrument. Since Fluegel instruments have a comparatively limited range, marked by instability and general lack of responsiveness in the third octave this includes all Fluegelhorns, ballad horns, vocal horns, Koenig horns, and related instruments , and since the tuba, like the euphonium, has a far greater range than most brasswinds, the tuba connexion seems most plausible. The Sax connexion is erroneous because it is based upon a miscomprehension of nomenclature. These terms also serve to confuse the distinction between these two instruments.

Jump to navigation Jump to search Crotal bell from Panama , gold, 6th th century Crotal bells Greek ‘crotalon’ – castanet or rattle are various types of small bells or rattles. They were produced in various Pre-Columbian cultures. In Europe they were made from probably before the early Middle Ages and though many founders cast bells of this type, the Robert Wells bell foundry of Aldbourne, Wiltshire produced the largest range.

The first medieval designs came in two separate halves into which a metal pea was introduced and the two halves were then soldered or crimped together. Somewhere around they were cast in a single piece with a ball of metal inside. They were often made of bronze with a slot cut down the side. These bells were used to warn other horse-drawn vehicle users mostly on country roads that another vehicle was approaching.

Don’t worry — your e-mail address is totally secure. I promise to use it only to send you Clock Collecting Tips. There are so many styles and types of clocks, made by so many clock makers and from so many countries, that I was totally lost. Over many years, I have learned a lot. I have concentrated on the American clock companies for my collection, so there is much for me to learn about clocks from outside the US. The question I get most from the comment form on this web site is: Some people will see a clock at an antique store that would look good in a certain room of their house, and end up with it that way.

However you might end up with your special clock, you probably would like to identify, date and generally learn more about it.

The first such place was undoubtedly in San Francisco. Most writers note 1 agree that the earliest temple was in present-day Chinatown: Both are claimed to have existed since the early s. However, whether one accepts such claims depends on how one understands historical continuity. It is not enough to rely on secondary sources or oral tradition. It is also not enough just to cite primary sources which state that a temple dedicated to the same deity or sponsored by the same organization formerly existed in the same area as the present one, as is the case with both the Tin How and Kong Chow temples.

Though he is famous for inventing the telephone, he also developed or helped develop a photophone which wirelessly communicated sound on a beam of light , a proto-metal detector, the airplane that made the first manned flight in the British Commonwealth, and a hydrofoil watercraft that set a marine speed record which stood for a decade.

Bell also had some legendarily eccentric work habits. With his shabby tweed clothes and bushy, often unkempt hair and beard, he was every inch the scientist savant. His offices and laboratories were environments of creative chaos, overflowing with enormous stacks of papers, books, and sketches, and strewn with wires, batteries, and research supplies of all kinds.

Bell also preferred to work through the night, going to bed as the sun came up, and sometimes driving himself so hard that the effort brought on migraine headaches. In more relaxed moments, he would skinny-dip in the lake by his summer home, floating on his back while puffing on a lit cigar, and the eruption of a thunderstorm might find him dashing outside in swimsuit and rubber boots to immerse himself in the natural spectacle.

While he liked to tinker and dream, he hated getting down to the brass tacks of experimentation; he detested dealing with details, the painstaking effort required to verify intuitions, the tedious process of making minute recalibrations, and then testing and re-resting variables. Unlike his fellow inventor, Thomas Edison, Bell even hated the work of commercializing his inventions — applying for patents and popularizing and improving that which he had already created while he was proud of developing the telephone, he considered the fuss entailed in protecting its patent and promoting its use an irritating distraction from his other work.

History[ edit ] Although forms of brass have been in use since prehistory , [39] its true nature as a copper-zinc alloy was not understood until the post medieval period because the zinc vapor which reacted with copper to make brass was not recognised as a metal. Many have similar tin contents to contemporary bronze artefacts and it is possible that some copper-zinc alloys were accidental and perhaps not even distinguished from copper.

There is good archaeological evidence for this process and crucibles used to produce brass by cementation have been found on Roman period sites including Xanten [66] and Nidda [67] in Germany , Lyon in France [68] and at a number of sites in Britain. The fabric of these crucibles is porous, probably designed to prevent a buildup of pressure, and many have small holes in the lids which may be designed to release pressure [68] or to add additional zinc minerals near the end of the process.

Dioscorides mentioned that zinc minerals were used for both the working and finishing of brass, perhaps suggesting secondary additions. These places would remain important centres of brass making throughout the medieval period, [82] especially Dinant.

For example, yellow brass bells have tones that are brighter, while rose brass bells have tones that are much warmer and more subtle. Moreover, it is possible for the bell of an instrument to be made of different materials from the rest of it.

Paul, MN Copper and its alloys, including brass and bronze, are among the oldest metals used by mankind. Dating back to ancient times, these metals gained wide use due to the ease with which their components were produced from ores. Copper also occurs in its native form in many places on our planet.

The rusty “button” protruding from the base of the two left-hand bells is the steel rivet that once attached these bells to their strap. The fourth bell is shown still attached to the strap. Antique acorn bells are not as rare as raspberry/fishscale bells.

Sheet-metal crotal bell 13th th century Alongside the early cast crotals, copper and copper-alloy bells of sheet metal were produced. On the very earliest of this type, the loop was made of circular-section wire, which was inserted through a small hole in the top of the bell and its ends splayed in the manner of a modern split-pin. Slightly later, a narrow strip of sheeting was used instead of wire, and was either fitted in the same way, or formed into a ring and soldered to the top of the bell as on the example illustrated.

Bells of this type have been recovered from secure contexts that span the date range circa mid th to mid th century. They are also found in a wide range of sizes, at least from 13mm to 34mm diameter, suggesting a variety of different uses. Around the end of the 13th century, a new type of white-metal pewter and tin crotal bell, cast in one piece, appears. The form is approximately spherical, but, as cast, the bottom half of the bell chamber is splayed.

This enables the pellet to be placed inside the bell, and the splayed half to be squeezed together to retain it. It also makes support of the core within the mould relatively easy. The earliest bells of this type have several moulded parallel ribs around the circumference, both vertically and horizontally. Later ones are often plain, but some have moulded decoration of various forms. The rounded ends of the sound bow are often very close to, or interrupt, the girth rib.

Decoration of thimbles, whether of brass or silver, also became commonplace, and inscriptions are often found around the base or within strap-work patterns. During the Commonwealth period, in particular, many such inscriptions are of a religious or moralistic nature.

Share This Though the history of metalworking is relatively young in Japan, craftsmen there developed alloys and the art of patination further there than any other metalworking culture. Their invention of specialized alloys allowed them to produce unique patinas. Today, metalsmiths are still experimenting with alloys, creating new ones, and improving on traditional combinations. In making these alloys, careful consideration of the desired results are given much attention, for small changes in ratios can have dramatic effects on the results.

Japanese artists have contributed significantly in another way, by using their unique alloys in innovative combinations. Perhaps the best example of this is mokume-gane, a lamination process in which layers of various alloys are manipulated to create a rich pattern. In addition, Japanese work of many periods shows highly skilled inlay techniques where, again, the complex pallette of Japanese alloys is used to achieve subtlety and a controlled use of color.

For most of the history of metalsmithing, workers were forced by necessity to make their own alloys. In earliest times, the now distinct skills of refining, alloying, moldmaking and casting were all rolled together into the profession of the metal artist. Still today, even though there are many fine alloys commercially available, it is not uncommon for artists to make their own alloys.

Sometimes this might be done to improve the ability of the metal to flow into a mold, or to increase its strength, but another practical reason to manipulate alloys is to influence the way they react to patina solutions. Ganoksin is sponsored by Making Alloys Sara-awase Most alloys used in cast sculpture contain copper as the principal ingredient. The practice of making alloys goes back to the earliest work, perhaps starting with an alloy of copper and tin, called in Japanese sei-do.

This material is an example of the mysterious nature of alloys.
