Machine

A machine is a tool containing one or more parts that uses energy to perform an intended action. Machines are usually powered by mechanical, chemical, thermal, or electrical means, and are often motorized. Historically, a power tool also required moving parts to classify as a machine. However, the advent of electronics has led to the development of power tools without moving parts that are considered machines.

A simple machine is a device that simply transforms the direction or magnitude of a force, but a large number of more complex machines exist. Examples include vehicles, electronic systems, molecular machines, computers, television, and radio.

Etymology

The word machine derives from the Latin word machina, which in turn derives from the Greek (Doric μαχανά makhana, Ionic μηχανή mekhane "contrivance, machine, engine", a derivation from μῆχος mekhos "means, expedient, remedy").

A wider meaning of "fabric, structure" is found in classical Latin, but not in Greek usage.

This meaning is found in late medieval French, and is adopted from the French into English in the mid-16th century.

Drum machine

A drum machine is an electronic musical instrument designed to imitate the sound of drums, cymbals, other percussion instruments, and often basslines. Drum machines are most commonly associated with electronic music genres such as house music, but are also used in many other genres. They are also used when session drummers are not available or if the production cannot afford the cost of a professional drummer.

In the 2010s, most modern drum machines are sequencers with a sample playback (rompler) or synthesizer component that specializes in the reproduction of drum timbres. Though features vary from model to model, many modern drum machines can also produce unique sounds, and allow the user to compose unique drum beats and patterns.

History

Early drum machines

In 1930–32, the spectacularly innovative and hard to use Rhythmicon was realized by D-Rail at the request of Henry Cowell, who wanted an instrument which could play compositions with multiple rhythmic patterns, based on the overtone series, were far too hard to perform on existing keyboard instruments. The invention could produce sixteen different rhythms, each associated with a particular pitch, either individually or in any combination, including en masse, if desired. Received with considerable interest when it was publicly introduced in 1932, the Rhythmicon was soon set aside by Cowell and was virtually forgotten for decades. The next generation of rhythm machines played only pre-programmed rhythms such as mambo, tango, or bossa nova.

Scooby-Doo

Scooby-Doo is an American animated cartoon franchise, comprising several animated television series produced from 1969 to the present day. The original series, Scooby-Doo, Where Are You!, was created for Hanna-Barbera Productions by writers Joe Ruby and Ken Spears in 1969. This Saturday-morning cartoon series featured four teenagers—Fred Jones, Daphne Blake, Velma Dinkley, and Norville "Shaggy" Rogers—and their talking brown Great Dane named Scooby-Doo, who solve mysteries involving supposedly supernatural creatures through a series of antics and missteps.

Following the success of the original series, Hanna-Barbera and its successor Warner Bros. Animation have produced numerous follow-up and spin-off animated series and several related works, including television specials and telefilms, a line of direct-to-video films, and two Warner Bros.–produced theatrical feature films. Some versions of Scooby-Doo feature different variations on the show's supernatural theme, and include characters such as Scooby's cousin Scooby-Dum and nephew Scrappy-Doo in addition to or instead of some of the original characters.
