supports: Pierre Henri Marie Schaeffer (, ; 14 August 1910  19 August 1995) was a French composer, writer, broadcaster, engineer, musicologist and acoustician. His innovative work in both the sciencesparticularly communications and acousticsand the various arts of music, literature and radio presentation after the end of World War II, as well as his anti-nuclear activism and cultural criticism garnered him widespread recognition in his lifetime. Experimental music is a compositional practice defined broadly by exploratory sensibilites and movement radically opposed to and questioning of institutionalized musical compositional, performing, and aesthetic conventions . The practice became prominent in the mid-20th century, particularly in North America. John Cage was one of the earliest composers to use the term and one of experimental music's primary innovators, utilizing indeterminacy techniques and seeking unknown outcomes. In France, as early as 1953, Pierre Schaeffer had begun using the term """" to describe compositional activities that incorporated tape music, musique concrète, and elektronische Musik. Also, in America, a quite distinct sense of the term was used in the late 1950s to describe computer-controlled composition associated with composers such as Lejaren Hiller. A brass instrument is a musical instrument that produces sound by sympathetic vibration of air in a tubular resonator in sympathy with the vibration of the player's lips. Brass instruments are also called "labrosones", literally meaning "lip-vibrated instruments". Computer software, or simply software, is that part of a computer system that consists of encoded information or computer instructions, in contrast to the physical hardware from which the system is built. John Milton Cage Jr. (September 5, 1912  August 12, 1992) was an American composer, music theorist, writer, philosopher, and artist. A pioneer of indeterminacy in music, electroacoustic music, and non-standard use of musical instruments, Cage was one of the leading figures of the post-war avant-garde. Critics have lauded him as one of the most influential American composers of the 20th century. He was also instrumental in the development of modern dance, mostly through his association with choreographer Merce Cunningham, who was also Cage's romantic partner for most of their lives. The trombone is a musical instrument in the brass family. Like all brass instruments, sound is produced when the player's vibrating lips (embouchure) cause the air column inside the instrument to vibrate. Nearly all trombones have a telescoping slide mechanism that varies the length of the instrument to change the pitch. Many modern trombone models also utilize a rotary valve as a means to lower pitch of the instrument. Variants such as the valve trombone and superbone have three valves like those on the trumpet. Lejaren Arthur Hiller (February 23, 1924 in New York City  January 26, 1994 in Buffalo, New York) was an American composer. In 1957 he collaborated with Leonard Issacson on his String Quartet No. 4, "Illiac Suite", the first significant use of a computer to compose music. In 1958 Hiller founded the Experimental Music Studio at the University of Illinois at Urbana-Champaign. His notable pupils included composers James Fulkerson, Larry Lake, Ilza Nogueira, David Rosenboom, Bernadette Speach and James Tenney. Musique concrète (meaning "concrete music") is a form of musique expérimentale (experimental music) that exploits acousmatic listening, meaning sound identities can often be intentionally obscured or appear unconnected to their source cause. It can feature sounds derived from recordings of musical instruments, the human voice, and the natural environment as well as those created using synthesizers and computer-based digital signal processing. Compositions in this idiom are not restricted to the normal musical rules of melody, harmony, rhythm, metre, and so on. Originally contrasted with "pure" "elektronische Musik" (based solely on the production and manipulation of electronically produced sounds rather than recorded sounds), the theoretical basis of "musique concrète" as a compositional practice was developed by Pierre Schaeffer, beginning in the early 1940s. From the late 1960s onward, and particularity in France, the term acousmatic music (musique acousmatique) started to used in reference to fixed media compositions that utilized both musique concrète based techniques and live sound spatialisation. Computer music is the application of computing technology in music composition, to help human composers create new music or to have computers independently create music, such as with algorithmic composition programs. It includes the theory and application of new and existing computer software technologies and basic aspects of music, such as sound synthesis, digital signal processing, sound design, sonic diffusion, acoustics, and psychoacoustics. The field of computer music can trace its roots back to the origins of electronic music, and the very first experiments and innovations with electronic instruments at the turn of the 20th century. The embouchure is the use of facial muscles and the shaping of the lips to the mouthpiece of woodwind instruments or the mouthpiece of the brass instruments. The word is of French origin and is related to the root "bouche" (fr.), 'mouth'. The proper embouchure allows the instrumentalist to play the instrument at its full range with a full, clear tone and without strain or damage to one's muscles. Algorithmic composition is the technique of using algorithms to create music. A composer (Latin "compn"; literally "one who puts together") is a person who creates or writes music, which can be vocal music (for a singer or choir), instrumental music (e.g., for solo piano, string quartet, wind quintet or orchestra) or music which combines both instruments and voices (e.g., opera or art song, which is a singer accompanied by a pianist). The core meaning of the term refers to individuals who have contributed to the tradition of Western classical music through creation of works expressed in written musical notation (e.g., sheet music scores). Sound design is the process of specifying, acquiring, manipulating or generating audio elements. It is employed in a variety of disciplines including filmmaking, television production, theatre, sound recording and reproduction, live performance, sound art, post-production, radio and video game development. Sound design most commonly involves the manipulation of previously composed or recorded audio, such as sound effects and dialogue. In some instances it may also involve the composition or manipulation of audio to create a desired effect or mood. A sound designer is one who practices the art of sound design. A trumpet is a musical 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 almost-closed lips (called the player's embouchure), producing a "buzzing" sound that starts a standing wave vibration in the air column inside the instrument. Since the late 15th century they have primarily been constructed of brass tubing, usually bent twice into a rounded rectangular shape.  George E. Lewis ( born July 14 , 1952 ) is a composer , electronic performer , installation artist , trombone player , and scholar in the fields of improvisation and experimental music . He has been a member of the Association for the Advancement of Creative Musicians ( AACM ) since 1971 , and is a pioneer of computer music . Digital signal processing (DSP) is the use of digital processing, such as by computers, to perform a wide variety of signal processing operations. The signals processed in this manner are a sequence of numbers that represent samples of a continuous variable in a domain such as time, space, or frequency. Acoustics is the interdisciplinary science that deals with the study of all mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound. A scientist who works in the field of acoustics is an acoustician while someone working in the field of acoustics technology may be called an acoustical engineer. The application of acoustics is present in almost all aspects of modern society with the most obvious being the audio and noise control industries. 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.
