The History of Computer Music
Computer music is a form of electronic music that uses computers to generate, process, manipulate, or organize sounds. Computer music can be traced back to the early experiments with electronic sound synthesis in the 1950s, when pioneers like Max Mathews, John Pierce, Jean-Claude Risset, James Tenney, Iannis Xenakis, and others used mainframe computers to create synthetic sounds and compositions.
Since then, computer music has evolved along with the development of computer technology, from the analog to the digital, from the mainframe to the personal computer, from the desktop to the laptop, from the software to the hardware, from the studio to the stage, from the offline to the online, and from the fixed to the interactive. Computer music has also expanded its scope and diversity, incorporating influences from various musical genres, cultures, and disciplines.
Today, computer music is a vibrant and dynamic field that encompasses a wide range of styles, techniques, and applications. Computer music composers can create sounds that are impossible or impractical to produce by acoustic means, manipulate sounds in ways that are beyond human perception or control, and organize sounds in complex and novel structures. Computer music can also interact with other media, such as video, graphics, text, or sensors, creating multimedia and multimodal experiences. Computer music can also engage with other performers, audiences, or environments, creating collaborative and participatory situations.
The Concepts of Computer Music
Computer music is different from traditional music in many ways. One of the main differences is that computer music does not rely on predefined musical elements, such as notes, scales, chords, or instruments. Instead, computer music composers can define their own musical elements, such as sounds, parameters, algorithms, or processes. This gives computer music composers more freedom and flexibility to create original and expressive musical works.
Some of the main concepts that computer music composers use to create their musical elements are:
Microsound is a term coined by Curtis Roads to describe sound events that are shorter than one-tenth of a second. Microsound is also known as sound particles or grains. Microsound is the smallest unit of sound that can be perceived by human ears. Microsound can be used to create complex sounds from simple grains by applying various operations, such as synthesis, processing, or organization.
Granular synthesis is a technique that uses microsound to synthesize sounds. Granular synthesis involves generating a large number of grains with different characteristics, such as frequency, amplitude, duration, envelope, or position. These grains are then combined in various ways to create complex sounds that can vary from smooth to noisy, from harmonic to inharmonic, from static to dynamic.
Sound morphing is a technique that uses microsound to transform sounds. Sound morphing involves analyzing two or more sounds into their constituent grains and then interpolating between them to create new sounds that have features of both. Sound morphing can be used to create hybrid sounds that blend different timbres, pitches, rhythms, or spatial locations.
Spatialization is a technique that uses microsound to create sound environments. Spatialization involves manipulating the position and movement of sounds in space using various methods, such as panning, reverberation, filtering, or delay. Spatialization can be used to create immersive sound environments that simulate realistic or imaginary spaces.
The Tools of Computer Music
Computer music composers use various software and hardware tools to create their musical works. These tools can range from simple applications that perform specific tasks to complex environments that allow for multiple functions and interactions. Some of the most popular and powerful tools that computer music composers use are:
Csound is one of the oldest and most versatile computer music languages. Csound was developed by Barry Vercoe at MIT in 1985 as an extension of Max Mathews' MUSIC-N family of languages. Csound allows users to write text-based code that specifies how sounds are generated and processed using various modules called opcodes. Csound can run on almost any platform and can produce high-quality audio output.
SuperCollider is a popular environment for live coding and interactive sound design. SuperCollider was developed by James McCartney in 1996 as an object-oriented language that combines features of Smalltalk and C++. SuperCollider allows users to write code that controls a server that performs audio synthesis and processing using various classes called UGens. SuperCollider can also communicate with other applications and devices using various protocols such as OSC or MIDI.
Max/MSP is a graphical programming platform for audio and video processing. Max/MSP was developed by Miller Puckette at IRCAM in 1988 as a visual language that uses graphical objects called boxes and wires to create patches that perform various functions. Max/MSP allows users to create interactive applications that can handle audio input and output using various objects called MSP objects.
The Works of Curtis Roads
Curtis Roads is not only a computer music theorist and educator, but also a computer music composer. He has created many works that demonstrate his mastery and innovation of computer music techniques, especially microsound and granular synthesis. Some of his most influential and innovative works are:
Point Line Cloud
Point Line Cloud is a masterpiece of microsound composition. Point Line Cloud was released in 2005 as a CD and DVD that contains 11 audiovisual pieces that explore the different forms and transformations of sound particles. Point Line Cloud uses granular synthesis to create sounds that range from pointillistic to dense, from linear to chaotic, from discrete to continuous. Point Line Cloud also uses spatialization and video synthesis to create stunning visualizations that match the sonic complexity.
Half-Life is a collaboration with video artist Brian O'Reilly. Half-Life was released in 2010 as a DVD that contains four audiovisual pieces that explore the concept of decay and regeneration. Half-Life uses granular synthesis and sound morphing to create sounds that decay from complex to simple, from harmonic to noisy, from organic to synthetic. Half-Life also uses video synthesis and processing to create images that decay from colorful to monochrome, from clear to distorted, from natural to artificial.
Now is a recent work that explores temporal perception. Now was released in 2017 as a CD that contains six pieces that manipulate time in different ways. Now uses granular synthesis and sound morphing to create sounds that stretch, compress, freeze, or reverse time. Now also uses spatialization and psychoacoustics to create illusions of temporal continuity or discontinuity.
