Trumpet
A trumpet is a brass instrument commonly used in classical and jazz ensembles. The trumpet group contains the instruments with the highest register in the brass family. Trumpet-like instruments have historically been used as signaling devices in battle or hunting, with examples dating back to at least 1500 BC; they began to be used as musical instruments only in the late 14th or early 15th century. Trumpets are used in art music styles, for instance in orchestras, concert bands, and jazz ensembles, as well as in popular music. They are played by blowing air through nearly-closed lips (called the player's embouchure), producing a "buzzing" sound that starts a standing wave vibration in the air column inside the instrument.
History of primitive, ancient Western and non-Western trumpets
The chromatic trumpet of Western tradition is a fairly recent invention, but primitive trumpets of one form or another have been in existence for millennia; some of the predecessors of the modern instrument are now known to date back to the Neolithic era. The earliest of these primordial trumpets were adapted from animal horns and sea shells, and were common throughout Europe, Africa, India and, to a lesser extent, the Middle East. Primitive trumpets eventually found their way to most parts of the globe, though even today indigenous varieties are quite rare in the Americas, the Far East and South-East Asia.
Doorbell
A doorbell is a signaling device typically placed near a door to a building's entrance. When a visitor presses a button the bell rings inside the building, alerting the occupant to the presence of the visitor. Although the first doorbells were mechanical, activated by pulling a cord, modern doorbells are generally electric switch. William Murdoch, a Scottish inventor, installed a number of his own innovations in his house, built in Birmingham in 1817; one of these was a loud doorbell, that worked using a piped system of compressed air. A precursor to the electric doorbell, specifically a bell that could be rung at a distance via an electric wire, was invented by Joseph Henry around 1831.
Fife (instrument)
A fife is a small, high-pitched, transverse aerophone, that is similar to the piccolo, but louder and shriller due to its narrower bore. The fife originated in medieval Europe and is often used in military and marching bands. Someone who plays the fife is called a fifer. The word "fife" comes from the German "Pfeife", or pipe, which comes from the Latin word "pipare". The fife is a simple instrument usually consisting of a tube with 6 finger holes, and diatonically tuned. Some have 10 or 11 holes for added chromatics. The fife also has an embouchure hole, across which the player blows, and a cork or plug inside the tube just above the embouchure hole.
USB
USB, short for Universal Serial Bus, is an industry standard that defines cables, connectors and communications protocols for connection, communication, and power supply between computers and devices. USB was designed to standardize the connection of computer peripherals (including keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters) to personal computers, both to communicate and to supply electric power. It has largely replaced a variety of earlier interfaces, such as serial ports and parallel ports, as well as separate power chargers for portable devices – and has become commonplace on a wide range of devices.
Mellophone
The mellophone is a three-valved brass instrument pitched in the key of F or E. It has a conical bore, like that of the euphonium and flugelhorn. The mellophone is used as the middle-voiced brass instrument in marching bands and drum and bugle corps in place of French horns, and can also be used to play French horn parts in concert bands and orchestras. These instruments are used instead of French horns for marching because their bells face forward instead of to the back (or to the side), as dissipation of the sound becomes a concern in the open-air environment of marching. Tuning is done solely by adjusting the tuning slide, unlike the French horn where the pitch is affected by the hand position in the bell.
Musical ensemble
A musical ensemble, also known as a music group or musical group, is a group of people who perform instrumental or vocal music, with the ensemble typically known by a distinct name. Some music ensembles consist solely of instruments, such as the jazz quartet or the orchestra. Some music ensembles consist solely of singers, such as choirs and doo wop groups. In both popular music and classical music, there are ensembles in which both instrumentalists and singers perform, such as the rock band or the Baroque chamber group for basso continuo (harpsichord and cello) and one or more singers. In classical music, trios or quartets either blend the sounds of musical instrument families (such as piano, strings, and wind instruments) or group together instruments from the same instrument family, such as string ensembles (e.g., string quartet) or wind ensembles (e.g., wind quintet).
