pDaniM: A case study on interactive processes for expressive music generation in the computer animataion production pipeline
This paper presents an experimental
application that shows how an interactive process can save time and production resources in the process pipeline of
music scoring for a 3D animation movie. This investigation uses as basis several rules (about 30) that performers use to
add certain expressive emotions to a score, covering different aspects of music performance. Basically, applying the rules
produces a rearrange in time and velocity parameters such as “microtiming”, articulation, tempo and sound level. The
resulting application should take as input a basic music score
(MIDI) quantized linearly, and imprint expressiveness and
emotion to this music in sync with the expressiveness cues from the timeline exported from the animation project.
Acoustic cues are driven by facial and gesture expression from the characters
The influence of body movements on children's perception of music with an ambiguous expressive character
The theory of embodied music cognition states that the perception and cognition of music is firmly, although not exclusively, linked to action patterns associated with that music. In this regard, the focus lies mostly on how music promotes certain action tendencies (i.e., dance, entrainment, etc.). Only recently, studies have started to devote attention to the reciprocal effects that people’s body movements may exert on how people perceive certain aspects of music and sound (e.g., pitch, meter, musical preference, etc.). The present study positions itself in this line of research. The central research question is whether expressive body movements, which are systematically paired with music, can modulate children’s perception of musical expressiveness. We present a behavioral experiment in which different groups of children (7–8 years, N = 46) either repetitively performed a happy or a sad choreography in response to expressively ambiguous music or merely listened to that music. The results of our study show indeed that children’s perception of musical expressiveness is modulated in accordance with the expressive character of the dance choreography performed to the music. This finding supports theories that claim a strong connection between action and perception, although further research is needed to uncover the details of this connection
Analyzing Visual Mappings of Traditional and Alternative Music Notation
In this paper, we postulate that combining the domains of information
visualization and music studies paves the ground for a more structured analysis
of the design space of music notation, enabling the creation of alternative
music notations that are tailored to different users and their tasks. Hence, we
discuss the instantiation of a design and visualization pipeline for music
notation that follows a structured approach, based on the fundamental concepts
of information and data visualization. This enables practitioners and
researchers of digital humanities and information visualization, alike, to
conceptualize, create, and analyze novel music notation methods. Based on the
analysis of relevant stakeholders and their usage of music notation as a mean
of communication, we identify a set of relevant features typically encoded in
different annotations and encodings, as used by interpreters, performers, and
readers of music. We analyze the visual mappings of musical dimensions for
varying notation methods to highlight gaps and frequent usages of encodings,
visual channels, and Gestalt laws. This detailed analysis leads us to the
conclusion that such an under-researched area in information visualization
holds the potential for fundamental research. This paper discusses possible
research opportunities, open challenges, and arguments that can be pursued in
the process of analyzing, improving, or rethinking existing music notation
systems and techniques.Comment: 5 pages including references, 3rd Workshop on Visualization for the

Timbre from Sound Synthesis and High-level Control Perspectives
International audienceExploring the many surprising facets of timbre through sound manipulations has been a common practice among composers and instrument makers of all times. The digital era radically changed the approach to sounds thanks to the unlimited possibilities offered by computers that made it possible to investigate sounds without physical constraints. In this chapter we describe investigations on timbre based on the analysis by synthesis approach that consists in using digital synthesis algorithms to reproduce sounds and further modify the parameters of the algorithms to investigate their perceptual relevance. In the first part of the chapter timbre is investigated in a musical context. An examination of the sound quality of different wood species for xylophone making is first presented. Then the influence of instrumental control on timbre is described in the case of clarinet and cello performances. In the second part of the chapter, we mainly focus on the identification of sound morphologies, so called invariant sound structures responsible for the evocations induced by environmental sounds by relating basic signal descriptors and timbre descriptors to evocations in the case of car door noises, motor noises, solid objects, and their interactions
Identification of expressive descriptors for style extraction in music analysis using linear and nonlinear models
La formalizaciĂłn de las interpretaciones expresivas aĂşn se considera relevante debido a la complejidad de la mĂşsica. La interpretaciĂłn expresiva forma un aspecto importante de la mĂşsica, teniendo en cuenta diferentes convenciones como gĂ©neros o estilos que una interpretaciĂłn puede desarrollar con el tiempo. Modelar la relaciĂłn entre las expresiones musicales y los aspectos estructurales de la informaciĂłn acĂşstica requiere una base probabilĂstica y estadĂstica mĂnima para la robustez, validaciĂłn y reproducibilidad de aplicaciones computacionales. Por lo tanto, es necesaria una relaciĂłn cohesiva y una justificaciĂłn sobre los resultados. Esta tesis se sustenta en la teorĂa y aplicaciones de modelos discriminativos y generativos en el marco del aprendizaje de maquina y la relaciĂłn de procedimientos sistemáticos con los conceptos de la musicologĂa utilizando tĂ©cnicas de procesamiento de señales y minerĂa de datos. Los resultados se validaron mediante pruebas estadĂsticas y una experimentaciĂłn no paramĂ©trica con la implementaciĂłn de un conjunto de mĂ©tricas para medir aspectos acĂşsticos y temporales de archivos de audio para entrenar un modelo discriminativo y mejorar el proceso de sĂntesis de un modelo neuronal profundo. Adicionalmente, el modelo implementado presenta la oportunidad para la aplicaciĂłn de procedimientos sistemáticos, automatizaciĂłn de transcripciones usando notaciĂłn musical, entrenamiento de habilidades auditivas para estudiantes de mĂşsica y mejorar la implementaciĂłn de redes neuronales profundas usando CPU en lugar de GPU debido a las ventajas de las redes convolucionales para el procesamiento de archivos de audio como vectores o matriz con una secuencia de notas.MaestrĂaMagister en IngenierĂa ElectrĂłnic
