Measuring Expressive Music Performances: a Performance Science Model using Symbolic Approximation

Music Performance Science (MPS), sometimes termed systematic musicology in Northern Europe, is concerned with designing, testing and applying quantitative measurements to music performances. It has applications in art musics, jazz and other genres. It is least concerned with aesthetic judgements or with ontological considerations of artworks that stand alone from their instantiations in performances. Musicians deliver expressive performances by manipulating multiple, simultaneous variables including, but not limited to: tempo, acceleration and deceleration, dynamics, rates of change of dynamic levels, intonation and articulation. There are significant complexities when handling multivariate music datasets of significant scale. A critical issue in analyzing any types of large datasets is the likelihood of detecting meaningless relationships the more dimensions are included. One possible choice is to create algorithms that address both volume and complexity. Another, and the approach chosen here, is to apply techniques that reduce both the dimensionality and numerosity of the music datasets while assuring the statistical significance of results. This dissertation describes a flexible computational model, based on symbolic approximation of timeseries, that can extract time-related characteristics of music performances to generate performance fingerprints (dissimilarities from an ‘average performance’) to be used for comparative purposes. The model is applied to recordings of Arnold Schoenberg’s Phantasy for Violin with Piano Accompaniment, Opus 47 (1949), having initially been validated on Chopin Mazurkas.1 The results are subsequently used to test hypotheses about evolution in performance styles of the Phantasy since its composition. It is hoped that further research will examine other works and types of music in order to improve this model and make it useful to other music researchers. In addition to its benefits for performance analysis, it is suggested that the model has clear applications at least in music fraud detection, Music Information Retrieval (MIR) and in pedagogical applications for music education

Tony Williams' drumset ideology to 1969: Synergistic emergence from an adaptive modeling of feel, technique and creativity as an archetype for cultivating originality in jazz drumset performance studies

I identify Tony Williams’ formative drumset ideology as being emergent from his adaptive modeling of the feel, technique and creativity identified in the drumming of Art Blakey, Max Roach and Philly Joe Jones respectively and present the results of extensive textual and musicological research on Williams’ formative practices between 1945 and 1969 as an archetype for cultivating originality in jazz drumset performance studies. I examine patterns of creative thought in the New York jazz community as they developed from the relative heteronomy of modernist bebop improvisation to the postmodernist aesthetic of jazz-rock fusion resulting in the emergence of collective autonomy in musical interaction and improvisation. My research reveals Willams’ possession of autotelic personality and utilisation of learning techniques associated with heutagogy. Also identified is the prevalence of entrainment in the social and musical interactions of the New York jazz community and I interpret these qualities through the lens of the theory of complex adaptive systems as a model for learning in jazz drumset performance studies. I analyse Williams’ ensemble and solo drumming in comparison to that of Blakey, Roach and Jones in addition to Roy Haynes by using an analytic schema designed specifically for identification of contrasting qualities in the voicing of rhythm and expression as revealed in the grouping and ordering of limbs in drumset performance. I present a complete stylistic overview of Williams’ recorded output until 1969 including swing, avant garde, ballad, straight eighth-note and sixteenth-note oriented styles as well as complex temporal events such as polymetric superimposition, rubato, polytempo, superimposed metric modulation, metric modulation and tempo fluctuation

Paradox, problem, and potential in secondary school jazz education

Thesis (D.M.A.)--Boston UniversitySeveral rationales for secondary school jazz education are commonly referenced in pedagogy manuals, advocacy literature, and instructional resources: jazz education can develop certain musicianship skills more effectively than traditional large ensemble classes (e.g., concert band), jazz education fosters lifelong music-making, jazz education can help build and sustain an audience for jazz, and jazz education is important because jazz holds a special place in American art and culture. The growth of jazz education, however, does not seem to have led to the expansion of the jazz audience and consumers in the USA or increased the likelihood of lifelong music making of students. Furthermore, jazz educators have not employed the kind of curricular structure and pedagogical practices necessary to take advantage of salient features of jazz in secondary music education. A close examination of the incongruence between rationales for jazz education and the practices of jazz education in secondary schools reveals certain paradoxes: student jazz participation grows, while broader jazz consumption ebbs; jazz education resources multiply, while diversity of theory and practice within jazz education diminishes; student jazz ensembles become more polished, but at the expense of developing skills that enhance students' personal music agency. I contend in this study that paradoxes such as these can be useful as a framework for problematizing as well as imagining (and ultimately enacting) possibilities. I propose that a "this-with-that" dialectic described by Jorgensen enables paradoxes to be analyzed and potentials to be discovered. I describe three paradoxes in secondary school jazz education with a twofold purpose: 1) to critique secondary school jazz education and offer recommendations based on this critique, and 2) to provide a practical example of how paradoxes in music education might be engaged by music educators. Although this project will have special significance to secondary school jazz educators because it offers a sustained critique in that area, it is my hope that this project will benefit music educators of all types as they encounter paradoxes in music education

Feeling the groove: shared time and its meanings for three jazz trios

The notion of groove is fundamental to jazz culture and the term yields a rich set of understandings for jazz musicians. Within the literature, no single perspective on groove exists and many questions remain about the relationship between timing processes, phenomenal experience and musical structures in making sense of groove. In this account, the experience and meaning of groove is theorised as emerging from two forms of sharedness. Firstly, a primary intersubjectivity that arises through the timing behaviours of the players; this could be likened to the 'mutual tuning-in' described in social phenomenology. It is proposed that this tuning-in is accomplished through the mechanism of entrainment. The second form of sharedness is understood as the shared temporal models, the cultural knowledge, that musicians make use of in their playing together. Methodologically, this study makes use of detailed investigation of timing data from live performances by three jazz trios, framed by in-depth, semi-structured interview material and steers a new course between existing ethnographic work on jazz and more psychologically informed studies of timing. The findings of the study point towards significant social and structural effects on the groove between players. The impact of musical role on groove and timing is demonstrated and significant temporal models, whose syntactic relations suggest musical proximity or distance, are shown to have a corresponding effect on timing within the trios. The musician's experience of groove is discussed as it relates to the objective timing data and reveals a complex set of understandings involving temporality, consciousness and communication. In the light of these findings, groove is summarised as the feeling of entrainment, inflected through cultural models and expressed through the cultural norms of jazz
