It introduces the concept of “embodied iconography”, which seeks to interpret historical images not merely as visual documents but as traces of the bodily and musical dynamics of the contexts in which they were created. Through the analysis of bodily postures in 19th-century iconographic representations related to capoeira and their comparison with contemporary motion recordings, the study reveals how the bodies depicted in the images can reflect complex musical and choreographic practices, exposing the distortions of colonial discourse. By linking historical and technological data, the study emphasizes the importance of embodiment studies in reconstructing cultural contexts and contributes to the decolonization of historiographical and musicological studies, offering new perspectives on Afro-Brazilian cultural practices

Introduz o conceito de “iconografia incorporada”, que busca interpretar imagens históricas não apenas como documentos visuais, mas como vestígios das dinâmicas corporais e musicais dos contextos em que foram criadas. A partir da análise de posturas corporais em representações iconográficas do século XIX relacionadas à capoeira e sua comparação com gravações de movimento contemporâneas, o estudo revela como os corpos representados nas imagens podem refletir práticas musicais e coreográficas complexas, exibindo as distorções do discurso colonial. Ao relacionar dados históricos e tecnológicos, o estudo destaca a importância dos estudos sobre a corporeidade na reconstrução de contextos culturais e contribui para a descolonização dos estudos historiográficos e musicológicos, oferecendo novas perspectivas sobre as práticas culturais afro-brasileiras

However, musicians add innumerous types of variations during performance, accounting for a range of differences within the boundaries of the style itself. Tango musicians are aware of these features when they speak about the melodic phrasing during performance. In some music styles, such as jazz and samba, the systematic recurrence of rhythmic-melodic patterns became an idiosyncratic feature that supports the identification of the style itself (Benadon, 2006; Naveda et al, 2011). An expressive characteristic of melodic phrasing in tango would consist of the production of temporal recurrences in the peculiar elongation and shortening of rhythmic-melodic patterns embedded in the microstructure of the phrase.

Embora as dimensoes de interpretacao da arte telematica ja tenham sido discutidas sob perspectivas similares, a obra “Embodied in varios Darmstadt’58" apresenta uma configuracao incomum de aberturas e aleatoriedades, complexidade e minimalismo, engenharia e arte, que permitem um aprofundamento distinto sobre as relacoes entre tecnologias, arte e cognicao. No decorrer do ensaio apresentaremos alguns conceitos norteadores no campo das teorias da mente incorporada e descreveremos parte dos processos de desenvolvimento de ferramentas computacionais utilizadas no processo de criacao. Argumentaremos que a complexidade dos conceitos criativos envolvidos do espetaculo promoveu a extensao de elementos poeticos da obra e cargas cognitivas ao dominio tecnologico das maquinas.

This workshop will continue previous discussions about the need for a NIME journal, and for solutions to share ideas, hardware designs, code, scores, and performances, systematically. Concerns about C19, climate change, and accessibility make these discussions urgent and demand reimagining our expectations for a publication venue. What solutions can we start implementing right away, and which goals do we have as a community? This open workshop will lay the ground for concrete experimentation in the year(s) to come.

Although the literature has discussed the telematic art from a variety of similar points of view, the project “Embodied in various Darmstadt’58” features an unusual conFiguretion of openings and randomness, complexity and minimalism, engineering and art, which allow a distinguished approach on the relationship between technology, art and cognition. In this essay, we present guiding concepts that substantiate the theories of embodied mind and describe part of development of computational tools used in the creative process. We argue that the complexity of creative concepts involved the performance had promoted the extension of poetic elements and cognitive loads to the technological domain of the machines.

How to support the demands for richer music-movement interactions? How to translate spatiotemporal qualities of human movement into relevant features for music making and sound design? In this paper we study the realtime interaction between choreographic movement in space and music, implemented by means of a collection of tools called Topos. The tools were developed in the Pure Data platform and provide a number of feature descriptions that help to map the quality of dance gestures in space to music and other media. The features are based concepts found in the literature of cognition and dance, which improves the computational representation of dance gestures in space. The concepts and techniques presented in...

In this study, we look at percussive forms of vocalizations in order to retrieve rhythmic models entrained by subjects in Samba culture. By analyzing recordings of vocal percussions collected from randomly selected Brazilian subjects, we aim at comparing emergent rhythmic structures with the current knowledge about Samba music forms. The database of recordings was processed using a psychoacoustically inspired auditory model and further displayed on loudness and onset images. The analyses of emergent rhythmic patterns show intriguing similarities with the findings in previous studies in the field and put different perspectives on the use of vocal forms in music information retrieval and musicology.

We aim at studying the design strategies used to interface music to other domains of the performance, in special, the application of wearable technologies into music performances. The project describes the development of the music and wearable interfaces, which comprise a hand interface and a mechanical actuator attached to the dancer’s dress. The performance resulted from the study is inspired in the butoh dances and attempts to add a technological poetic as music-dance-wearable interactions to the traditional dialogue between dance and music.

This representation is based on a video analysis of body movements, carried out from the viewpoint of the musical meter. Our method provides the periods, a measure of energy and a visual representation of periodic movement in dance. The method is applied to a limited universe of Samba dances and music, which is used to illustrate the usefulness of the approach.

However, the production and perception of rhythm in Afro-Brazilian contexts is often described as a result of multiple experience flows, which expands the description of rhythmical events to multiple features such as loudness, spectrum regions, metrical layers, movement and others. In this study, we analyzed how the microtiming of samba music interacts with an expanded set of musical descriptors. More specifically, we analyzed the interaction between fast timing structures with meter, intensity and spectral distribution within the auditory domain. The methodology for feature detection was supported by a psychoacoustically based auditory model, which provided the low-level descriptors for a database of 106 samba music excerpts. A cluster analysis technique was used to provide an overview of emergent microtiming models present in ...
