In this paper I try to outline a model that can bring out the meaningful relationships between ‘the instrumental’ and ‘the electronics’ in mixed music. The model is based on the semiotic square which is considered in semiotics as a powerful conceptual framework to examine the relationships between two terms (S1/S2) and their negative (non-S1/non-S2), terms which can be characters, situations, actions, concepts, etc. Two paradigmatic axes represent the relations between the actors of mixed music: the sources (instrumental and electronic) on the one hand, and the manipulations (real-time processing and sound projection) on the other. According to the semiotic square, the relations inside the environment are defined in terms of contrariety, contradiction and complementarity. This model allows us to start out with a purely technological description of the ‘mixed music’ genre and of individual pieces, with the advantage of a pre-operative analysis of the system. It describes the immanent structure of the environments and releases the potential interactions between the instrumental and the electronics of mixed music. These interactions are examined, from a paradigmatic point of view, with numerous representative pieces of mixed music from the twentieth century.

The musicologist is confronted with many situations during the analysis of electroacoustic music, whether on support media, mixed, or real-time. Musical genres and styles vary greatly, and the collection of electronic musical instruments has also proven to be very heterogeneous. The intrinsic characteristics of the electroacoustic parts and their scoring create serious limitations. Furthermore, many sources remain inaccessible or are already lost. Thus the preoccupation with documentary sources related to the acts of creation, interpretation, and technological context becomes more and more pressing. It is now essential to formulate a synthetic vision of this music, which has existed for half a century, and to pursue the search for invariants. This work must be based on a rigorous methodology that has yet to be developed. More generally speaking, the goal is to establish the terms and conditions of a systematic musicology of electroacoustics.

An electroacoustic musical work is a complex network of processes and elements: technical, musical, human, etc.; therefore, while the aesthetic perception is unified, its definition is fragmentary. This observation compels us to intensify our study of a taxonomy of agents and processes, with the aim of clarifying the identity of this music.

The discussion is positioned according to two different vantage points: (i) analysis of works, and (ii) the writings devoted to the aesthetics of electroacoustic music. Musicological analysis is simultaneously the means, the goal and the motivation for getting to know this arborescent reality. It allows us to arrive at the identification of six agents and four processes associated with the work, whose main properties we will describe. These elements are used as a methodological and theoretical grid for organising the discussion about the works. The question centres on a paradigm which is created from the analysis and returns to it, as an essential link between hermeneutic knowledge and the knowledge of the internal logic of an electroacoustic work.

Art always does more than subsist upon technical progress; for centuries its practice has merged with it, and we should never forget that the first meaning of the word art was technê. However, never before has the relationship between art and technology raised so many questions and provoked so much misunderstanding. As a matter of fact, at the same time as the frontiers of technique continue to recede, the frontiers of art seem more and more difficult to grasp. (Couchot and Hillaire 2003: 15)

Portraits polychromes are a series of books associated with multimedia documents presented on the Internet site of the GRM since 2001. In releasing this collection, our primary concern was to increase awareness of the electroacoustic repertoire and the reserves in the GRM archives. The GRM, being a pioneering centre of electroacoustics, is fortunate to possess a consistent and significant reserve dating back to the beginning of the 1950s. At present, the catalogue contains around 2,000 works, accompanied with supplementary documents: composer's biographies, reviews, photographs, documentary movies, radio broadcasts, recorded public lectures, theoretical research work, transcriptions and analyses. In addition to the heritage value of the GRM's collection, the enterprise of the Portraits polychromes, with the aid of multimedia tools, aims to advance the progress of research on analysis and the transcription of musical works.

Electroacoustic music has been of great interest to Latin American composers since its inception. Hundreds of composers have been working in this field, creating thousands of pieces. However, there is a significant lack of information and recordings in this respect, and little research has been conducted in this area until recently. One step forward to advance the exploration of a somewhat lost sound world is The Latin American Electroacoustic Music Collection, a documentation, preservation and dissemination project, developed by the author.

This paper seeks to address some of the problems faced by those archiving an area of musical practice – electroacoustic music and the sonic arts – which is, by definition, involved with technologies which change and develop, and which unsurprisingly is itself in a state of flux and transformation. Drawing on the experience gained from two linked research projects – one looking at the development of the practice, the other seeking to archive it – it is suggested that the two apparently disparate areas of activity can be fruitfully regarded as overlapping in many respects. Both activities involve selection and aesthetic judgement, both strive for an elusive ‘completeness’ while acknowledging its impossibility, and at a technical level the strategies now emerging for searching and collating information from ‘separate’ archives look increasingly like the strategies used in some areas of ‘real-time’ composition and performance practice. It is argued that archivists of material from such a disparate and rapidly developing practice, rather than aiming for spurious ‘coverage’ of the field, should acknowledge and celebrate their difference from each other, while conforming to simple principles which will allow their archived content to be searched and collated dynamically by individual users, each querying and configuring the material optimally for their own purposes.

One of the most remarkable achievements of Pierre Schaeffer's musical thought is his proposal of the sonorous object as the focus of research. The sonorous object is a fragment of sound, typically in the range of a few seconds (often even less), perceived as a unit. Sonorous objects are constituted, studied, and evaluated according to various criteria, and sonorous objects that are found suitable are regarded as musical objects that may be used in musical composition. In the selection and qualification of these sonorous objects, we are encouraged to practise what Schaeffer called ‘reduced listening’, meaning disregarding the original context of the sound, including its source and signification, and instead focus our listening on the sonorous features.

However, it can be argued that this principle of ‘reduced listening’ is not in conflict with more fundamental principles of embodied cognition, and that the criteria for the constitution, and the various feature qualifications, of sonorous objects can be linked to gestural images. Also, there are several similarities between studying sound and gestures from a phenomenological perspective, and it is suggested that Schaeffer's theoretical concepts may be extended to what is called gestural-sonorous objects.

Edgard Varèse's Poème électronique can be viewed as a bridge between early twentieth-century modernism and electroacoustic music. This connection to early modernism is most clearly seen in its use of musical juxtaposition, a favoured technique of early modernist composers, especially those active in Paris. Juxtaposition and non-motion are considered here, particularly in relationship to Smalley's exposition of spectromorphology (Smalley 1986), which in its preoccupation with motion omits any significant consideration of non-motion. Juxtaposition and non-motion have an important history within twentieth-century music, and as an early classic of electroacoustic music, Poème électronique is a particularly striking example of a composition that is rich in juxtapositions similar to those found in passages of early modernist music. Examining Poème électronique through the lens of juxtaposition and non-motion reveals how the organisation of its juxtaposed sounds encourages the experience of sound structure suspended time.

The word ‘noise’ has taken on various meanings throughout the course of twentieth-century music. Technology has had direct influence on the presence of noise, as phenomenon and as concept, both through its newfound ubiquity in modernity and through its use directly in music production – in electroacoustics. The creative use of technologies has lead to new representation systems for music, and noise – considered as that outside of a given representation – was brought into meaning. This paper examines several moments in which a change in representation brought noise into musical consideration – leading to a ‘noise music’ for its time before simply becoming understood as music.

A casual listener may not have the relevant cognitive tools to relate to electroacoustic music as an independent art form. Even music students who have had several years' formal training may not know how to listen purposefully to it. The authors investigate the hypothesis that by engaging in the composition of musique concrète, students will become more informed listeners to electroacoustic music in general. This study describes a teacher and ten 16-year-old high school students who use a digital audio editor (Cool Edit Pro) to manipulate sound and to structure sound events. A variety of teaching approaches are tested. Having experienced the creative process, the participants display a growing ability to engage in higher-order critical thinking skills in relation to electroacoustic music.

The Intention/Reception (I/R) project concerns an investigation of the relationship between composer intention and listener response in electroacoustic (E/A) compositions. Phase one of the project focuses on E/A compositions that contain or are perceived to contain real-world sound references (RWE/A). The methodology involves introducing works that are unknown to the listening subjects and then evaluating their listening experience. Through repeated listening and the introduction of the composers' articulation of intent (through a work's title, inspiration, elements that the composer intends to be communicated, eventually elements of the compositional process itself – in short, the ‘dramaturgy’ of the work) listening responses are monitored. The purpose here is to investigate to what extent familiarity contributes to access and appreciation and to what extent intention and reception are meeting in this particular corpus of E/A art music.

This paper offers an introduction to the I/R project outlining its background, its context and presenting pertinent points concerning the design and operation of its methodology. Following this, some of the key results discovered thus far, including the first presentation of test data that formed the basis of the conclusions of a recently completed doctoral thesis, will be shared.
