is a companion website to the book Emergent Musical Forms: Aural Explorations. The Aural Sonology Project represents a novel approach to the analysis of sonic and structural aspects of music-as-heard, developed at the Norwegian Academy of Music. Its method of analysis and theory is not uniquely reserved for a particular compositional style or expression. A central concern for the project is the development of aural consciousness through a systematic application of different ways of listening. Audio-visual technology facilitates the creation and the presentation of the aural sonology analyses. The approach is particularly useful for dealing with music for which no score is available (e.g. electroacoustic music) or (instrumental) music in which there is no simple one-to-one correspondence between a score and the aural phenomenon. A complete presentation of the project is published in Emergent Musical Forms: Aural Explorations by Lasse Thoresen with the assistance of Andreas Hedman (Studies in Music of the University of Western Ontario).

As part of the artistic development project The Reflective Musician, Lasse Thoresen made analyses of the interpretive strategies employed by Sergey Rachmaninoff in his Chopin interpretation. The analysis is demonstrated by analytical movies, found at the present web-page under Further Analyses. The paper is entitled Extreme Interpretation? Some observations on Rachmaninoff’s interpretation of Chopin’s Third Ballade in A-flat Major, op. 47 no. 3. Sensorial Aesthetics in Musical Practices. Kathleen Coessens, ed. Leuven University Press 2019. ISBN 9789461662910. It can be purchased here.

When spectral music came to Norway in the 1980s it quickly merged with other composition techniques and concepts. The first piece of spectral music made in Norway was Lasse Thoresen’s Illuminations/Les enluminures. On June 14 he presented a paper on the story, including analyses of the piece, at the seminar Spectralisms 2019 at IRCAM, Paris. The presentation can be seen here. The complete paper is published here: Spectral Mergers. How Spectral Music came to Norway.

Eilif Balkır defended her PhD dissertation September 7, 2018 in Paris. The title of her dissertation is: Étude comparative des approches créatrices et technologiques au Groupe de Recherches Musicales à Paris et à Elektronmusikstudion à Stockholm 1965–1980. Deux directions artistiques différentes à partir d’une idée commune. The PhD is the result of a “cotutelle” between Stockholm University, Department of Culture and Aesthetics, and Sorbonne University. Balkır examines interactions between Pierre Schaeffer (Groupe de Recherches Musicales) and Knut Wiggen (Elektronmusikstudion)—pioneers of electroacoustic music in France and Sweden—and the evolution of artistic directions within their respective institutions. Aural Sonology is central to Balkır’s analyses of pioneer works which forms a part of the basis for her research, and the end goal is to determine a methodology for an in-depth understanding of acousmatic music analysis and to establish an historical documentation on French and Swedish electroacoustic music within the development of technology. The dissertation may be read in full-text at the portal for publications at Stockholm University. Language: French.

Nicolas Marty defended his PhD-thesis Les conduites d’écoute. Temps, espace et forme dans les musiques acousmatiques at Université Paris-Sorbonne, École Doctorale V, Laboratoire de recherche IReMus. Marty’s main subject is that of listening behaviours, originally an idea proposed by François Delalande. He discusses and criticizes the extensions of the idea presented in Emergent Musical Forms. He presents analytical movies of electroacoustic music, in which he applies selected analytical tools from Aural Sonology.

Andreas Angell has published his Master’s thesis “Timbre, texture and spiritual symbolism in Gubaidulina’s two works, De profundis and Et expecto. Aural sonology as a tool to explore sonic and structural aspects of interpretation in contemporary accordion music” in Applied Music Theory at the Norwegian Academy of Music. Excerpt from abstract: “This thesis concerns multiple aural analyses of the pieces for accordion by Sofia Gubaidulina; De Profundis and Et Exspecto. Through aural sonology, this research focuses on the exploration of emerging gestalts through performance and interpretation. Unlike a traditional analysis of the music manifested in the score, this approach concerns sonic and structural elements that are heard through the recorded performance. (…) The goal of this thesis is to ascertain which timbral musical objects are heard, illuminate the structural forms of the music and make an interpretation of the symbolic meaning in the chosen works”. Videos of the aural analyses may be found here.

Marcelo Nicolino, a Brazilian musician and researcher, has published his Master’s dissertation “The sound design spectromorphology: the listening score as a tool to analyze the cinematic sound design composition” in Music/Sonology at the University of São Paulo. The main subject is the use of Thoresen’s spectromorphology theory as a practical tool for film sound design analysis. As a case study, Nicolino analyzed five sequences from F.F. Coppola’s The Conversation (1974), sound design by Walter Murch. Several videos of the analyses may be found here. Language: Portuguese.

Alessio Elia earns the PhD degree in Story, Science and Techniques of Music at the University of Rome Tor Vergata with the dissertation: The “Hamburgisches Konzert” by György Ligeti. From sketches and drafts to the final (?) version. Musical structures, techniques of composition and their perception as aural phenomena. Aural Sonology is used for analysing form-building in Ligeti’s Hamburgisches Konzert.
