Music Roll
A music roll () is a storage medium used to operate a mechanical musical instrument. They are used for the player piano, mechanical organ, electronic carillon and various types of orchestrion. The vast majority of music rolls are made of paper. Other materials that have been utilized include thin card (Imhof-system), thin sheet brass (Telektra-system), composite multi-layered electro-conductive aluminium and paper roll (Triste-system) and, in the modern era, thin plastic or PET film. The music data is stored by means of perforations. The mechanism of the instrument reads these as the roll unwinds, using a pneumatic, mechanical or electrical sensing device called a tracker bar, and the mechanism subsequently plays the instrument. After a roll is played, it is necessary for it to be rewound before it can be played again. This necessitates a break in a musical performance. To overcome this problem, some instruments were built with two player mechanisms (referred to as a duple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reproducing Piano
A player piano is a self-playing piano with a pneumatic or electromechanical mechanism that operates the piano action using perforated paper or metallic rolls. Modern versions use MIDI. The player piano gained popularity as mass-produced home pianos increased in the late 19th and early 20th centuries. Sales peaked in 1924 and subsequently declined with improvements in electrical phonograph recordings in the mid-1920s. The advent of electrical amplification in home music reproduction, brought by radios, contributed to a decline in popularity, and the stock market crash of 1929 virtually wiped out production. History The first practical pneumatic piano player, manufactured by the Aeolian Company and called the "Pianola", was invented in 1896 by Edwin S. Votey, and came into widespread use in the 20th century. The name "pianola", sometimes used as a generic name for any player piano, came from this invention. The mechanism of this player piano was all-pneumatic: foot-operated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacquard Loom
The Jacquard machine () is a device fitted to a loom that simplifies the process of manufacturing textiles with such complex patterns as brocade, damask and matelassé. The resulting ensemble of the loom and Jacquard machine is then called a Jacquard loom. The machine was patented by Joseph Marie Jacquard in 1804, based on earlier inventions by the Frenchmen Basile Bouchon (1725), Jean Baptiste Falcon (1728), and Jacques Vaucanson (1740). The machine was controlled by a "chain of cards"; a number of punched cards laced together into a continuous sequence. Multiple rows of holes were punched on each card, with one complete card corresponding to one row of the design. Both the Jacquard process and the necessary loom attachment are named after their inventor. This mechanism is probably one of the most important weaving innovations, as Jacquard shed (weaving), shedding made possible the automatic production of unlimited varieties of complex pattern weaving. The term "Jacquard" is no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Punched Tape

It was developed from and was subsequently used alongside punched cards, the difference being that the tape is continuous. Punched cards, and chains of punched cards, were used for control of looms in the 18th century. Use for telegraphy systems started in 1842. Punched tapes were used throughout the 19th and for much of the 20th centuries for programmable looms, teleprinter communication, for input to computers of the 1950s and 1960s, and later as a storage medium for minicomputers and Numerical control, CNC machine tools. During the Second World War, high-speed punched tape systems using opti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piano Roll
A piano roll is a music storage medium used to operate a player piano, piano player or reproducing piano. Piano rolls, like other music rolls, are continuous rolls of paper with holes punched into them. These perforations represent note control data. The roll moves over a reading system known as a tracker bar; the playing cycle for each musical note is triggered when a perforation crosses the bar. Piano rolls have been in continuous production since at least 1896, and are still being manufactured today; QRS Music offers 45,000 titles with "new titles being added on a regular basis", although they are no longer mass-produced. MIDI files have generally supplanted piano rolls in storing and playing back performance data, accomplishing digitally and electronically what piano rolls do mechanically. MIDI editing software often features the ability to represent the music graphically as a piano roll. The first paper rolls were used commercially by Welte & Sons in their orchestrions ...

Book Music
A book is a structured presentation of recorded information, primarily verbal and graphical, through a medium. Originally physical, electronic books and audiobooks are now existent. Physical books are objects that contain printed material, mostly of writing and images. Modern books are typically composed of many pages Bookbinding, bound together and protected by a Book cover, cover, what is known as the ''codex'' format; older formats include the scroll and the Clay tablet, tablet. As a conceptual object, a ''book'' often refers to a written work of substantial length by one or more authors, which may also be distributed digitally as an electronic book (ebook). These kinds of works can be broadly Library classification, classified into fiction (containing invented content, often narratives) and non-fiction (containing content intended as factual truth). But a physical book may not contain a written work: for example, it may contain ''only'' drawings, engravings, photographs, s ...

Wurlitzer
The Rudolph Wurlitzer Company, usually referred to as simply Wurlitzer, is an American company started in Cincinnati in 1853 by German immigrant (Franz) Rudolph Wurlitzer. The company initially imported stringed, woodwind and brass instruments from Germany for resale in the United States. Wurlitzer enjoyed initial success, largely due to defense contracts to provide musical instruments to the U.S. military. In 1880, the company began manufacturing pianos and eventually relocated to North Tonawanda, New York. It quickly expanded to make fairground organ, band organs, orchestrions, player pianos and pipe organs, pipe or theatre organs popular in theatres during the days of silent movies. Wurlitzer also operated a chain of retail stores where the company's products were sold. As technology evolved, Wurlitzer began producing Wurlitzer electric piano, electric pianos, electronic organs and jukeboxes, and it eventually became known more for jukeboxes and vending machines, which are s ...

Organ Pipe
An organ pipe is a sound-producing element of the pipe organ that resonator, resonates at a specific Pitch (music), pitch when pressurized air (commonly referred to as ''wind'') is driven through it. Each pipe is tuned to a note of the musical scale. A set of organ pipes of similar timbre comprising the complete scale is known as a rank; one or more ranks constitutes a Organ stop, stop. Construction Materials Organ pipes are generally made out of either metal or wood. Very rarely, glass, porcelain, plastic, paper, Papier-mâché, or even Rock (geology), stone pipes may be seen. A Las Piñas Bamboo Organ, historical organ in the Philippines has pipes made exclusively of bamboo. Metal Metal pipes are usually made of lead; for increased rigidity it is alloyed with tin along with trace amounts of antimony and copper. The percentage of each metal in the alloy influences the characteristics of the resulting pipe. A high proportion of tin results in a slightly brighter colour (optica ...

Pneumatic
Pneumatics (from Greek 'wind, breath') is the use of gas or pressurized air in mechanical systems. Pneumatic systems used in Industrial sector, industry are commonly powered by compressed air or compressed inert gases. A centrally located and electrically-powered Gas compressor, compressor powers Pneumatic cylinder, cylinders, air motors, pneumatic actuators, and other pneumatic devices. A pneumatic system controlled through manual or automatic solenoid valves is selected when it provides a lower cost, more flexible, or safer alternative to electric motors, and hydraulic actuators. Pneumatics also has applications in dentistry, construction, mining, and other areas. History Although the early history of pneumatics is somewhat unclear, blowguns are often considered the earliest pneumatic device, being created independently by various indigenous groups around the world. Bellows are an early form of air compressor used primarily for smelting and forging. Ctesibius of Alexand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
