Live plants have been used as musical instruments, especially in electronic music.
Live plants can be used as electronic musical instrument by running a weak electric current through them and by amplifying the way the current is changed when the plants are touched, or by applying contact microphones and amplifying the projection and tone of the sounds produced when handling them [1] .
John Cage composed Child of Tree (1975) and Branches (1976) for what he described as "amplified plant materials". Cage was a proponent of chance music and felt that the organic nature of music without man-made instruments was very strong and influential. The percussion group So Percussion gave a concert in 2007 featuring Cage's pieces, where percussionist "Jason Treuting played an amplified cactus, running his hand over the plant's unfriendly spikes to produce an alluring sound like a babbling brook." [2]
Another piece for amplified cactus is Degrees of Separation "Grandchild of Tree" by Paul Rudy which received mention at the Bourges International Competition for Electroacoustic Music in 2000. [3] Rudy mentions in his own program notes: [4]
The idea for a cactus and tape work came about when I heard a performance of John Cage's Child of Tree. I was immediately taken with the sound of the cactus in particular. Taken from its natural environment and placed in the confined and groomed existence of a pot, amplified with a contact microphone, the cactus took on a completely new and interesting character...
A piece by Mark Andre, ...zu Staub... also features three amplified cacti alongside classical instruments.
In 2007, the French digital artist duo Scenocosme created a sound installation where visitors create sounds by touching the leaves of plants in pots haning from the ceiling. [5]
A drum kit is a collection of drums, cymbals, and sometimes other auxiliary percussion instruments set up to be played by one person. The player (drummer) typically holds a pair of matching drumsticks, one in each hand, and uses their feet to operate a foot-controlled hi-hat and bass drum pedal.
John Milton Cage Jr. was an American composer and music theorist. 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 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.
A prepared piano is a piano that has had its sounds temporarily altered by placing bolts, screws, mutes, rubber erasers, and/or other objects on or between the strings. Its invention is usually traced to John Cage's dance music for Bacchanale, created without room for a percussion orchestra. Cage has cited Henry Cowell as an inspiration for developing piano extended techniques, involving strings within a piano being manipulated instead of the keyboard. Typical of Cage's practice as summed up in the Sonatas and Interludes (1946–48) is that each key of the piano has its own characteristic timbre, and that the original pitch of the string will not necessarily be recognizable. Further variety is available with use of the una corda pedal.
Noise music is a genre of music that is characterised by the expressive use of noise within a musical context. This type of music tends to challenge the distinction that is made in conventional musical practices between musical and non-musical sound. Noise music includes a wide range of musical styles and sound-based creative practices that feature noise as a primary aspect.
Audio feedback is a positive feedback situation which may occur when an acoustic path exists between an audio input and an audio output. In this example, a signal received by the microphone is amplified and passed out of the loudspeaker. The sound from the loudspeaker can then be received by the microphone again, amplified further, and then passed out through the loudspeaker again. The frequency of the resulting howl is determined by resonance frequencies in the microphone, amplifier, and loudspeaker, the acoustics of the room, the directional pick-up and emission patterns of the microphone and loudspeaker, and the distance between them. The principles of audio feedback were first discovered by Danish scientist Søren Absalon Larsen, hence it is also known as the Larsen effect.
4′33″ is a three-movement composition by American experimental composer John Cage. It was composed in 1952, for any instrument or combination of instruments, and the score instructs performers not to play their instruments during the entire duration of the piece throughout the three movements. The piece consists of the sounds of the environment that the listeners hear while it is performed, although it is commonly perceived as "four minutes thirty-three seconds of silence". The title of the piece refers to the total length in minutes and seconds of a given performance, 4′33″ being the total length of the first public performance.
Max Neuhaus was an American musician, composer and artist who was a noted interpreter of contemporary and experimental percussion music in the 1960s. He went on to create numerous permanent and short-term sound installations in the four decades that followed.
Timothy "Tim" George Hodgkinson is an English experimental music composer and performer, principally on reeds, lap steel guitar, and keyboards. He first became known as one of the core members of the British avant-rock group Henry Cow, which he formed with Fred Frith in 1968. After the demise of Henry Cow, he participated in numerous bands and projects, eventually concentrating on composing contemporary music and performing as an improviser.
A contact microphone, also known as a piezo microphone, is a form of microphone that senses audio vibrations through contact with solid objects. Unlike normal air microphones, contact microphones are almost completely insensitive to air vibrations but transduce only structure-borne sound. Often used as acoustic leakage probes, they also enjoy wide usage by noise music artists experimenting with sound. Contact microphones can be used to amplify sound from acoustic musical instruments, to sense drum hits, for triggering electronic samples, and to record sound in challenging environments, such as underwater under high pressure.
An experimental musical instrument is a musical instrument that modifies or extends an existing instrument or class of instruments, or defines or creates a new class of instrument. Some are created through simple modifications, such as cracked drum cymbals or metal objects inserted between piano strings in a prepared piano. Some experimental instruments are created from household items like a homemade mute for brass instruments such as bathtub plugs. Other experimental instruments are created from electronic spare parts, or by mixing acoustic instruments with electric components.
Orchestral enhancement is the technique of using orchestration techniques, architectural modifications, or electronic technologies to modify the sound, complexity, or color of a musical theatre, ballet or opera pit orchestra. Orchestral enhancements are used both to create new sounds and to add capabilities to existing orchestral ensembles.
Sō Percussion is an American percussion quartet formed in 1999 and based in New York City.
Live electronic music is a form of music that can include traditional electronic sound-generating devices, modified electric musical instruments, hacked sound generating technologies, and computers. Initially the practice developed in reaction to sound-based composition for fixed media such as musique concrète, electronic music and early computer music. Musical improvisation often plays a large role in the performance of this music. The timbres of various sounds may be transformed extensively using devices such as amplifiers, filters, ring modulators and other forms of circuitry. Real-time generation and manipulation of audio using live coding is now commonplace.
In music, noise is variously described as unpitched, indeterminate, uncontrolled, loud, unmusical, or unwanted sound. Noise is an important component of the sound of the human voice and all musical instruments, particularly in unpitched percussion instruments and electric guitars. Electronic instruments create various colours of noise. Traditional uses of noise are unrestricted, using all the frequencies associated with pitch and timbre, such as the white noise component of a drum roll on a snare drum, or the transients present in the prefix of the sounds of some organ pipes.
Imaginary Landscape No. 3 is a composition for six percussionists by American composer John Cage and the third in the series of Imaginary Landscapes. It is the last Imaginary Landscape to feature percussion instruments and, therefore, the last one to be considered a chamber piece. It was composed in 1942.
Imaginary Landscape No. 2 is a composition for five percussionists by American composer John Cage and the second in the series of Imaginary Landscapes. It was also the first march in the set, the second being Imaginary Landscape No. 4 . It was composed in 1942.
But what about the noise of crumpling paper which he used to do in order to paint the series of "Papiers froissés" or tearing up paper to make "Papiers déchirés?" Arp was stimulated by water, forests, sometimes shortened as But what about the noise..., is a composition for percussion ensemble by American composer John Cage. It was finished in 1985.
The implementation of sound technology by Drum Corps International is a phenomenon in the twenty-first century marching arts. Since 2004, many corps have used electronics to amplify, alter, and add to the sound of their ensembles.
