Evolutionary Music
Evolutionary music is the audio counterpart to evolutionary art, whereby algorithmic music is created using an evolutionary algorithm. The process begins with a population of individuals which by some means or other produce audio (e.g. a piece, melody, or loop), which is either initialized randomly or based on human-generated music. Then through the repeated application of computational steps analogous to biological selection, recombination and mutation the aim is for the produced audio to become more musical. Evolutionary sound synthesis is a related technique for generating sounds or synthesizer instruments. Evolutionary music is typically generated using an interactive evolutionary algorithm where the fitness function is the user or audience, as it is difficult to capture the aesthetic qualities of music computationally. However, research into automated measures of musical quality is also active. Evolutionary computation techniques have also been applied to harmonizatio ...

Evolutionary Art
Evolutionary art is a branch of generative art, in which the artist does not do the work of constructing the artwork, but rather lets a system do the construction. In evolutionary art, initially generated art is put through an iterated process of selection and modification to arrive at a final product, where it is the artist who is the selective agent. Evolutionary art is to be distinguished from BioArt, which uses living organisms as the material medium instead of paint, stone, metal, etc. Overview In common with biological evolution through natural selection or animal husbandry, the members of a population undergoing artificial evolution modify their form or behavior over many reproductive generations in response to a selective regime. In interactive evolution the selective regime may be applied by the viewer explicitly by selecting individuals which are aesthetically pleasing. Alternatively a selection pressure can be generated implicitly, for example according to the leng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Generative Music
Generative music is a term popularized by Brian Eno to describe music that is ever-different and changing, and that is created by a system. Historical background In 1995 whilst working with SSEYO's Koan software (built by Tim Cole and Pete Cole who later evolved it to Noatikl then Wotja), Brian Eno used the term "generative music" to describe any music that is ever-different and changing, created by a system. The term has since gone on to be used to refer to a wide range of music, from entirely random music mixes created by multiple simultaneous CD playback, through to live rule-based computer composition. Koan was SSEYO's first real-time music generation system, developed for the Windows platform. Work on Koan was started in 1990, and the software was first released to the public in 1994. In 1995 Brian Eno started working with SSEYO's Koan Pro software, work which led to the 1996 publication of his title 'Generative Music 1 with SSEYO Koan Software'. Eno's early relationship ...

Algorithmic Composition
Algorithmic composition is the technique of using algorithms to create music. Algorithms (or, at the very least, formal sets of rules) have been used to compose music for centuries; the procedures used to plot voice-leading in Western counterpoint, for example, can often be reduced to algorithmic determinacy. The term can be used to describe music-generating techniques that run without ongoing human intervention, for example through the introduction of chance procedures. However through live coding and other interactive interfaces, a fully human-centric approach to algorithmic composition is possible. Some algorithms or data that have no immediate musical relevance are used by composers as creative inspiration for their music. Algorithms such as fractals, L-systems, statistical models, and even arbitrary data (e.g. census figures, GIS coordinates, or magnetic field measurements) have been used as source materials. Models for algorithmic composition Compositional algorithms are u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MIDI
MIDI (; Musical Instrument Digital Interface) is a technical standard that describes a communications protocol, digital interface, and electrical connectors that connect a wide variety of electronic musical instruments, computers, and related audio devices for playing, editing, and recording music. The specification originates in the paper ''Universal Synthesizer Interface'' published by Dave Smith and Chet Wood of Sequential Circuits at the 1981 Audio Engineering Society conference in New York City. A single MIDI cable can carry up to sixteen channels of MIDI data, each of which can be routed to a separate device. Each interaction with a key, button, knob or slider is converted into a MIDI event, which specifies musical instructions, such as a note's pitch, timing and loudness. One common MIDI application is to play a MIDI keyboard or other controller and use it to trigger a digital sound module (which contains synthesized musical sounds) to generate sounds, which t ...

Melomics
Melomics (derived from "genomics of melodies") is a computational system for the automatic composition of music (with no human intervention), based on bioinspired algorithms. Technological aspects Melomics applies an evolutionary approach to music composition, i.e., music pieces are obtained by simulated evolution. These themes compete to better adapt to a proper fitness function, generally grounded on formal and aesthetic criteria. The Melomics system encodes each theme in a genome, and the entire population of music pieces undergoes evo-devo dynamics (i.e., pieces read-out mimicking a complex embryological development process). The system is fully autonomous: once programmed, it composes music without human intervention. This technology has been transferred to industry as an academic spin-off, Melomics Media, which has provided and reprogrammed a new computer cluster that created a huge collection of popular music. The results of this evolutionary computation are being sto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TheGuardian
''The Guardian'' is a British daily newspaper. It was founded in 1821 as ''The Manchester Guardian'', and changed its name in 1959. Along with its sister papers ''The Observer'' and ''The Guardian Weekly'', ''The Guardian'' is part of the Guardian Media Group, owned by the Scott Trust Limited, Scott Trust. The trust was created in 1936 to "secure the financial and editorial independence of ''The Guardian'' in perpetuity and to safeguard the journalistic freedom and liberal values of ''The Guardian'' free from commercial or political interference". The trust was converted into a limited company in 2008, with a constitution written so as to maintain for ''The Guardian'' the same protections as were built into the structure of the Scott Trust by its creators. Profits are reinvested in journalism rather than distributed to owners or shareholders. It is considered a newspaper of record in the UK. The editor-in-chief Katharine Viner succeeded Alan Rusbridger in 2015. Since 2018, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DarwinTunes
DarwinTunes was a research project into the use of natural selection to create music led by Bob MacCallum and Armand Leroi, scientists at Imperial College London. The project asks volunteers on the Internet to listen to automatically generated sound loops and rate them based on aesthetic preference. After the volunteers rate the loops on a five-point scale, software permits the highest rated loops to 'reproduce sexually' and populate the next generation of musical loops. In a paper published in the Proceedings of the National Academy of Sciences, the DarwinTunes developers describe how their first experimental population derived from two randomly generated founding loops, allowed 100 generations of loops to evolve without any selection pressure before asking members of the public to rate the loops. The paper found that for the first 500 to 600 generations, aesthetic quality of the loops dramatically improved before reaching a stable equilibrium. They tested this using ratings by list ...

L-system
An L-system or Lindenmayer system is a parallel rewriting system and a type of formal grammar. An L-system consists of an alphabet of symbols that can be used to make strings, a collection of production rules that expand each symbol into some larger string of symbols, an initial "axiom" string from which to begin construction, and a mechanism for translating the generated strings into geometric structures. L-systems were introduced and developed in 1968 by Aristid Lindenmayer, a Hungarian theoretical biologist and botanist at the University of Utrecht. Lindenmayer used L-systems to describe the behaviour of plant cells and to model the growth processes of plant development. L-systems have also been used to model the morphology of a variety of organisms and can be used to generate self-similar fractals. Origins As a biologist, Lindenmayer worked with yeast and filamentous fungi and studied the growth patterns of various types of bacteria, such as the cyanobacteria '' Anabaena ...

Microsoft Windows
Windows is a group of several proprietary graphical operating system families developed and marketed by Microsoft. Each family caters to a certain sector of the computing industry. For example, Windows NT for consumers, Windows Server for servers, and Windows IoT for embedded systems. Defunct Windows families include Windows 9x, Windows Mobile, and Windows Phone. The first version of Windows was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). Windows is the most popular desktop operating system in the world, with 75% market share , according to StatCounter. However, Windows is not the most used operating system when including both mobile and desktop OSes, due to Android's massive growth. , the most recent version of Windows is Windows 11 for consumer PCs and tablets, Windows 11 Enterprise for corporations, and Windows Server 2022 for servers.

Eurovision Song Contest
The Eurovision Song Contest (), sometimes abbreviated to ESC and often known simply as Eurovision, is an international songwriting competition organised annually by the European Broadcasting Union (EBU), featuring participants representing primarily European countries. Each participating country submits an original song to be performed on live television and radio, transmitted to national broadcasters via the EBU's Eurovision and Euroradio networks, with competing countries then casting votes for the other countries' songs to determine a winner. Based on the Sanremo Music Festival held in Italy since 1951, Eurovision has been held annually since 1956 (apart from ), making it the longest-running annual international televised music competition and one of the world's longest-running television programmes. Active members of the EBU, as well as invited associate members, are eligible to compete, and 52 countries have participated at least once. Each participating broadcaster se ...
