From Harmony to the Field

This document expounds a brief history of Western musical art, from the mid-nineteenth century to the beginning of the twenty first, which traces the complete transformation of its expressive means and materials. Examined are the changes to Western music’s basic materials such as pitch system, timbral palette and formal architecture. We observe as these aspects are dismantled, supplanted by a dramatically expanded sonic palette and subsequently expanded ranges of expression and topical consideration. This brief historiography contextualizes my current working theories and methods for the construction and understanding of electroacoustic music, centered around the idea of The Field, which frames my work and my views of others’ works. But more importantly, The Field is an attempt to move the model for work away from human rationality and place it in an aspect of the world. Next, a chronological survey a selection of recent work will elucidate a shift in my own expressive materials and media. This is followed by the relating of the genesis and context of my thesis work, field: alarum, implication (v.2), situating it in The Field and in the body of work. Ultimately, this paper exemplifies my striving to understand and contextualize my practice and to deepen and focus my practical, theoretical and critical engagement with it

A Corpus Approach to Roman Law Based on Justinian’s Digest

Traditional philological methods in Roman legal scholarship such as close reading and strict juristic reasoning have analysed law in extraordinary detail. Such methods, however, have paid less attention to the empirical characteristics of legal texts and occasionally projected an abstract framework onto the sources. The paper presents a series of computer-assisted methods to open new frontiers of inquiry. Using a Python coding environment, we have built a relational database of the Latin text of the Digest, a historical sourcebook of Roman law compiled under the order of Emperor Justinian in 533 CE. Subsequently, we investigated the structure of Roman law by automatically clustering the sections of the Digest according to their linguistic profile. Finally, we explored the characteristics of Roman legal language according to the principles and methods of computational distributional semantics. Our research has discovered an empirical structure of Roman law which arises from the sources themselves and complements the dominant scholarly assumption that Roman law rests on abstract structures. By building and comparing Latin word embeddings models, we were also able to detect a semantic split in words with general and legal sense. These investigations point to a practical focus in Roman law which is consistent with the view that ancient law schools were more interested in training lawyers for practice rather than in philosophical neatness.</jats:p

Algorithmic Compositional Methods and their Role in Genesis: A Multi-Functional Real-Time Computer Music System

Algorithmic procedures have been applied in computer music systems to generate compositional products using conventional musical formalism, extensions of such musical formalism and extra-musical disciplines such as mathematical models. This research investigates the applicability of such algorithmic methodologies for real-time musical composition, culminating in Genesis, a multi-functional real-time computer music system written for Mac OS X in the SuperCollider object-oriented programming language, and contained in the accompanying DVD. Through an extensive graphical user interface, Genesis offers musicians the opportunity to explore the application of the sonic features of real-time sound-objects to designated generative processes via different models of interaction such as unsupervised musical composition by Genesis and networked control of external Genesis instances. As a result of the applied interactive, generative and analytical methods, Genesis forms a unique compositional process, with a compositional product that reflects the character of its interactions between the sonic features of real-time sound-objects and its selected algorithmic procedures. Within this thesis, the technologies involved in algorithmic methodologies used for compositional processes, and the concepts that define their constructs are described, with consequent detailing of their selection and application in Genesis, with audio examples of algorithmic compositional methods demonstrated on the accompanying DVD. To demonstrate the real-time compositional abilities of Genesis, free explorations with instrumentalists, along with studio recordings of the compositional processes available in Genesis are presented in audiovisual examples contained in the accompanying DVD. The evaluation of the Genesis system’s capability to form a real-time compositional process, thereby maintaining real-time interaction between the sonic features of real-time sound objects and its selected algorithmic compositional methods, focuses on existing evaluation techniques founded in HCI and the qualitative issues such evaluation methods present. In terms of the compositional products generated by Genesis, the challenges in quantifying and qualifying its compositional outputs are identified, demonstrating the intricacies of assessing generative methods of compositional processes, and their impact on a resulting compositional product. The thesis concludes by considering further advances and applications of Genesis, and inviting further dissemination of the Genesis system and promotion of research into evaluative methods of generative techniques, with the hope that this may provide additional insight into the relative success of products generated by real-time algorithmic compositional processes

Activating the archive through generative systems – Remaking images from the Aalto rare books collection

The focus of this thesis is on generative processes applied in the context of art and design. Specifically, it looks at the conception and application of a suitable analogue generative system utilised for working with archival material from the Aalto Visual Resources Centre. The project is documented in detail to describe the process from conception through execution in a systematic and transparent way. The review of three different taxonomies and the analysis of selected works, as well as the identification of artists’ motivations for using generative systems, are used to define the scope of generative art as well as to define and discuss the thesis project

Reconsidering cultural entrepreneurship: hip hop music economy and social change in Senegal, francophone West Africa

The increasing interest in the cultural economy is part of an attempt to invent new industrial development strategies that comprises a capacity to transform locations. In policy-making, the cultural economy is commonly framed from an economic perspective that salutes the role of the cultural economy and the dynamics of entrepreneurship in processes of urban and regional developments. Moreover, explorations of cultural economy and entrepreneurship are mainly represented by studies of Europe and North America. This thesis departs from such a normative perspective, and critically examines the links between a situated music economy, its cultural entrepreneurs and social change in West Africa. The empirical investigation of West African hip hop musical practitioners is framed by the notion of “community of practice”. The situated practices of these cultural workers and their music production ecology are investigated – methodologically – from a grounded perspective in order to grasp the originality of their materiality and aesthetics. The empirical focus of this thesis research is Dakar, one Francophone West African urban locale, which is contrasted with the ‘test case’ site of Ouagadougou. The case study locations are ‘experientially situated’, and over seventy semi-structured interviews were conducted with a range of participants both directly and indirectly involved in the hip hop music economy. Underpinning this research is the starting point that using “community of practice” as a conceptual framework offers a theoretically informed empirical basis for situating cultural entrepreneurship in the context of the West African music economy. In response, this thesis introduces the transcultural dimension of Hip Hop to frame its radical culturalisation of the West African music economy. This is done by singling out the political, social and theoretical significance of how hip hop entrepreneurship has become a force to be reckoned within social change in Francophone West Africa: this is a significant contribution of the thesis

An Artificial Intelligence Approach to Concatenative Sound Synthesis

Sound examples are included with this thesisTechnological advancement such as the increase in processing power, hard disk capacity and network bandwidth has opened up many exciting new techniques to synthesise sounds, one of which is Concatenative Sound Synthesis (CSS). CSS uses data-driven method to synthesise new sounds from a large corpus of small sound snippets. This technique closely resembles the art of mosaicing, where small tiles are arranged together to create a larger image. A ‘target’ sound is often specified by users so that segments in the database that match those of the target sound can be identified and then concatenated together to generate the output sound. Whilst the practicality of CSS in synthesising sounds currently looks promising, there are still areas to be explored and improved, in particular the algorithm that is used to find the matching segments in the database. One of the main issues in CSS is the basis of similarity, as there are many perceptual attributes which sound similarity can be based on, for example it can be based on timbre, loudness, rhythm, and tempo and so on. An ideal CSS system needs to be able to decipher which of these perceptual attributes are anticipated by the users and then accommodate them by synthesising sounds that are similar with respect to the particular attribute. Failure to communicate the basis of sound similarity between the user and the CSS system generally results in output that mismatches the sound which has been envisioned by the user. In order to understand how humans perceive sound similarity, several elements that affected sound similarity judgment were first investigated. Of the four elements tested (timbre, melody, loudness, tempo), it was found that the basis of similarity is dependent on humans’ musical training where musicians based similarity on the timbral information, whilst non-musicians rely on melodic information. Thus, for the rest of the study, only features that represent the timbral information were included, as musicians are the target user for the findings of this study. Another issue with the current state of CSS systems is the user control flexibility, in particular during segment matching, where features can be assigned with different weights depending on their importance to the search. Typically, the weights (in some existing CSS systems that support the weight assigning mechanism) can only be assigned manually, resulting in a process that is both labour intensive and time consuming. Additionally, another problem was identified in this study, which is the lack of mechanism to handle homosonic and equidistant segments. These conditions arise when too few features are compared causing otherwise aurally different sounds to be represented by the same sonic values, or can also be a result of rounding off the values of the features extracted. This study addresses both of these problems through an extended use of Artificial Intelligence (AI). The Analysis Hierarchy Process (AHP) is employed to enable order dependent features selection, allowing weights to be assigned for each audio feature according to their relative importance. Concatenation distance is used to overcome the issues with homosonic and equidistant sound segments. The inclusion of AI results in a more intelligent system that can better handle tedious tasks and minimize human error, allowing users (composers) to worry less of the mundane tasks, and focusing more on the creative aspects of music making. In addition to the above, this study also aims to enhance user control flexibility in a CSS system and improve similarity result. The key factors that affect the synthesis results of CSS were first identified and then included as parametric options which users can control in order to communicate their intended creations to the system to synthesise. Comprehensive evaluations were carried out to validate the feasibility and effectiveness of the proposed solutions (timbral-based features set, AHP, and concatenation distance). The final part of the study investigates the relationship between perceived sound similarity and perceived sound interestingness. A new framework that integrates all these solutions, the query-based CSS framework, was then proposed. The proof-of-concept of this study, ConQuer, was developed based on this framework. This study has critically analysed the problems in existing CSS systems. Novel solutions have been proposed to overcome them and their effectiveness has been tested and discussed, and these are also the main contributions of this study.Malaysian Minsitry of Higher Education, Universiti Putra Malaysi

Music in Motion: Diversity and Dialogue in Europe; Study in the frame of the "ExTra! Exchange Traditions" project

Diverse musical cultures of migrant and minority communities have existed in Europe for centuries and shaped its countries significantly. As part of an EU-funded project this volume deals with the musical activities of minorities and their impact on musical traditions in Europe. It also raises questions such as: How are musical traditions of minorities integrated in education and the public music life? Can music facilitate transcultural dialogue? And to what extent do musical practice and performance reassert the own cultural tradition in a foreign environment? Answers to those and similar questions as well as a review on what can be observed in the 21st century Europe are gathered in various thematic approaches. The book also provides model projects with a practical insight into the life and work with music of migrant and minority cultures across Europe
