The Electronic Journal Of Combinatorics

Two musicians performed on the piano, one in the traditional manner, the other playing on the strings, frame, and case. Two other performers used tape to unite the presentation of live sounds with the future of prerecorded materials from later on and its past of recordings made earlier in the performance. Critics of musical conventions at the time saw promise in these developments.

During the 1960s, digital computer music was pioneered, innovation in live electronics took place, and Japanese electronic musical instruments began to influence the music industry. In the early 1970s, Moog synthesizers and Japanese drum machines helped popularize synthesized electronic music. The 1970s also saw electronic music begin to have a significant influence on popular music, with the adoption of polyphonic synthesizers, electronic drums, drum machines and turntables, through the emergence of genres such as disco, krautrock, new wave, synth-pop, hip hop and EDM. In the early 1980s mass-produced digital synthesizers, such as the Yamaha DX7, became popular, and MIDI was developed. In the same decade, with a greater reliance on synthesizers and the adoption of programmable drum machines, electronic popular music came to the fore.

Paul Hindemith and Ernst Toch composed several pieces in 1930 by layering recordings of instruments and vocals at adjusted speeds. Influenced by these techniques, John Cage composed Imaginary Landscape No. 1 in 1939 by adjusting the speeds of recorded tones. Avant-garde composers criticized the predominant use of electronic instruments for conventional purposes. The instruments offered expansions in pitch resources that were exploited by advocates of microtonal music such as Charles Ives, Dimitrios Levidis, Olivier Messiaen and Edgard Varèse. Further, Percy Grainger used the theremin to abandon fixed tonation entirely, while Russian composers such as Gavriil Popov treated it as a source of noise in otherwise-acoustic noise music.

When a key is pressed the tape head contacts the moving tape and plays a sound. The Mellotron was the most notable model, used by many groups in the late 1960s and the 1970s, but such systems were expensive and heavy due to the multiple tape mechanisms involved, and the range of the instrument was limited to three octaves at the most. To change sounds a new set of tapes had to be installed in the instrument. After the arrival of punk rock, a form of basic electronic rock emerged, increasingly using new digital technology to replace other instruments. The American duo Suicide, who arose from the punk scene in New York, utilized drum machines and synthesizers in a hybrid between electronics and punk on their eponymous 1977 album. Simultaneously in San Francisco, composer Stan Shaff and equipment designer Doug McEachern, presented the first “Audium” concert at San Francisco State College , followed by work at the San Francisco Museum of Modern Art , conceived of as in time, controlled movement of sound in space.

Twelve speakers surrounded the audience, four speakers were mounted on a rotating, mobile-like construction above. In an SFMOMA performance the following year , San Francisco Chronicle music critic Alfred Frankenstein commented, "the possibilities of the space-sound continuum have seldom been so extensively explored". In 1967, the first Audium, a "sound-space continuum" opened, holding weekly performances through 1970. In 1975, enabled by seed money from the National Endowment for the Arts, a new Audium opened, designed floor to ceiling for spatial sound composition and performance. Musique concrète was introduced to Japan by Toshiro Mayuzumi, who was influenced by a Pierre Schaeffer concert.

They predicted expansions in timbre allowed for by electronics in the influential manifesto The Art of Noises . Due to the complex nature of electronics theory, laboratory experimentation is an important part of the development of electronic devices. These experiments are used to test or verify the engineer's design and detect errors.

These developments led to the growth of synth-pop, which after it was adopted by the New Romantic movement, allowed synthesizers to dominate the pop and rock music of the early 1980s until the style began to fall from popularity in the mid-to-end of the decade. Along with aforementioned successful pioneers, key acts included Yazoo, Duran Duran, Spandau Ballet, Culture Club, Talk Talk, Japan, and Eurythmics. In the late 1960s, pop and rock musicians, including the Beach Boys and the Beatles, began to use electronic instruments, like the theremin and Mellotron, to supplement and define their sound. Also in the late 1960s, the music duo Silver Apples and experimental rock bands like White Noise and the United States of America, are regarded as pioneers to the electronic rock and electronica genres for their work in melding psychedelic rock with oscillators and synthesizers. Filed in 1964 (See Drum machine#History), which he released as the FR-1 Rhythm Ace drum machine the same year.

These techniques were used to compose soundtracks for several films in Germany and Russia, in addition to the popular Dr. Jekyll and Mr. Hyde in the United States. Experiments with graphical sound were continued by Norman McLaren from the late 1930s. Developments of the vacuum tube led to electronic instruments that were smaller, amplified, and more practical for performance. In particular, the theremin, ondes Martenot and trautonium were commercially produced by the early 1930s. This paper proposes a channel sounder to measure the channel properties of an implantable device that transmits data from inside to outside the human body. The proposed channel sounder measures the receiving power of a signal transmitted from outside the human body.
