Context: The Telharmonium (also known as the Dynamophone) was an early electrical organ, developed by Thaddeus Cahill circa 1896 and patented in 1897. The electrical signal from the Telharmonium was transmitted over wires; it was heard on the receiving end by means of "horn" speakers., An electronic musical instrument is a musical instrument that produces sound using electronics. Such an instrument sounds by outputting an electrical audio signal that ultimately drives a loudspeaker., The Hammond organ is an electric organ, invented by Laurens Hammond and John M. Hanert and first manufactured in 1935. Various models have been produced, most of which use sliding drawbars to create a variety of sounds. Until 1975, Hammond organs generated sound by creating an electric current from rotating a metal tonewheel near an electromagnetic pickup, and then strengthening the signal with an amplifier so that it can drive a speaker cabinet. Around two million Hammond organs have been manufactured. The organ is commonly used with, and associated with, the Leslie speaker., Endless Summer is an album by Austrian electronic music producer Fennesz , released on 3 July 2001 by Mego . It was reissued in 2006 with two bonus tracks and new cover art. Like most of Fennesz 's other works , it focuses heavily on digitally manipulated electric guitar sounds , but with a much stronger emphasis on melodies and pop - like composition than on his previous releases . Endless Summer shares its title with a 1974 Beach Boys compilation album . It was named the 41st best album of the decade by Resident Advisor , 14th by Tiny Mix Tapes , and 26th by Pitchfork Media ., The guitar is a musical instrument classified as a string instrument with anywhere from four to 18 strings, usually having six. The sound is projected either acoustically, using a hollow wooden or plastic and wood box (for an acoustic guitar), or through electrical amplifier and a speaker (for an electric guitar). It is typically played by strumming or plucking the strings with the fingers, thumb and/or fingernails of the right hand or with a pick while fretting (or pressing against the frets) the strings with the fingers of the left hand. The guitar is a type of chordophone, traditionally constructed from wood and strung with either gut, nylon or steel strings and distinguished from other chordophones by its construction and tuning. The modern guitar was preceded by the gittern, the vihuela, the four-course Renaissance guitar, and the five-course baroque guitar, all of which contributed to the development of the modern six-string instrument., Christian Fennesz (born 25 December 1962) is an Austrian guitarist and composer active in electronic music, often credited on recordings simply as Fennesz., A synthesizer (often abbreviated as synth, also spelled synthesiser) is an electronic musical instrument that generates electric signals that are converted to sound through instrument amplifiers and loudspeakers or headphones. Synthesizers may either imitate instruments like piano, Hammond organ, flute, vocals; natural sounds like ocean waves, etc.; or generate new electronic timbres. They are often played with a musical keyboard, but they can be controlled via a variety of other input devices, including music sequencers, instrument controllers, fingerboards, guitar synthesizers, wind controllers, and electronic drums. Synthesizers without built-in controllers are often called "sound modules", and are controlled via MIDI or CV/Gate using a controller device, often a MIDI keyboard or other controller., An electric guitar is a fretted string instrument that uses a pickup to convert the vibration of its stringswhich are typically made of steel, and which occurs when a guitarist strums, plucks or fingerpicks the stringsinto electrical signals. The vibrations of the strings are sensed by a pickup, of which the most common type is the magnetic pickup, which uses the principle of direct electromagnetic induction. The signal generated by an electric guitar is too weak to drive a loudspeaker, so it is plugged into a guitar amplifier before being sent to a loudspeaker, which makes a sound loud enough to hear. The output of an electric guitar is an electric signal, and the signal can easily be altered by electronic circuits to add "color" to the sound or change the sound. Often the signal is modified using effects such as reverb and distortion and "overdrive", with the latter being a key element of the sound of the electric guitar as it is used in blues and rock music., Electronic music is music that employs electronic musical instruments and electronic music technology in its production, an electronic musician being a musician who composes and/or performs such music. In general, a distinction can be made between sound produced using electromechanical means and that produced using electronic technology. Examples of electromechanical sound producing devices include the telharmonium, Hammond organ, and the electric guitar. Purely electronic sound production can be achieved using devices such as the theremin, sound synthesizer, and computer., The theremin (originally known as the ætherphone/etherphone, thereminophone or termenvox/thereminvox) is an early electronic musical instrument controlled without physical contact by the thereminist (performer). It is named after the Westernized name of its Russian inventor, Léon Theremin (é), who patented the device in 1928., A computer is a device that can be instructed to carry out an arbitrary set of arithmetic or logical operations automatically. The ability of computers to follow a sequence of operations, called a "program", make computers very flexible and useful. Such computers are used as control systems for a very wide variety of industrial and consumer devices. This includes simple special purpose devices like microwave ovens and remote controls, factory devices such as industrial robots and computer assisted design, but also in general purpose devices like personal computers and mobile devices such as smartphones. The Internet is run on computers and it connects millions of other computers., Subject: endless summer , Relation: performer, Options: (A) a (B) amplifier (C) cahill (D) change (E) christian fennesz (F) classified (G) composer (H) electronic (I) five (J) m (K) means (L) mobile (M) natural (N) ocean (O) projected (P) renaissance (Q) the sound (R) various
