Bowing the violin : a case study for auditory-motor pattern modelling in the context of music performance

This project addresses methodological and technological challenges in the development of multi-modal data acquisition and analysis methods for the representation of instrumental playing technique in music performance through auditory-motor patterning models. The case study is violin playing: a multi-modal database of violin performances has been constructed by recording different musicians while playing short exercises on different violins. The exercise set and recording protocol have been designed to sample the space defined by dynamics (from piano to forte) and tone (from sul tasto to sul ponticello), for each bow stroke type being played on each of the four strings (three different pitches per string) at two different tempi. The data, containing audio, video, and motion capture streams, has been processed and segmented to facilitate upcoming analyses. From the acquired motion data, the positions of the instrument string ends and the bow hair ribbon ends are tracked and processed to obtain a number of bowing descriptors suited for a detailed description and analysis of the bow motion patterns taking place during performance. Likewise, a number of sound perceptual attributes are computed from the audio streams. Besides the methodology and the implementation of a number of data acquisition tools, this project introduces preliminary results from analyzing bowing technique on a multi-modal violin performance database that is unique in its class. A further contribution of this project is the data itself, which will be made available to the scientific community through the repovizz platform.

In search of good relationships to music : understanding aspiration and challenge in developing music school teacher practices

This study focuses on teacher practices in publicly funded music schools in Finland. As views on the aims of music education change and broaden, music schools across Europe share the challenge of developing their activities in response. In public and scholarly debate, there have been calls for increased diversity of contents and concepts of teaching. In Finland, the official national curriculum for state-funded music schools builds on the ideal that teaching and learning should create conditions which promote ‘a good relationship to music’. The meaning of this concept has been deliberately left open in order to leave room for dialogue, flexibility, and teacher autonomy. Since what is meant by ‘good’ is not defined in advance, the notion of ‘improving’ practices is also open to discussion. The purpose of the study is to examine these issues from teachers’ point of view by asking what music school teachers aim to accomplish as they develop their practices. Methodologically, the study introduces a suggestion for building empirical research on Alperson’s ‘robust’ praxial approach to music education, a philosophical theory which is strongly committed to practitioner perspectives and musical diversity. A systematic method for analysing music education practices, interpretive practice analysis, is elaborated with support from interpretive research methods originally used in policy analysis. In addition, the research design shows how reflecting conversations (a collaborative approach well-known in Nordic social work) can be fruitfully applied in interpretive research and combined with teacher inquiry. Data have been generated in a collaborative project involving five experienced music school teachers and the researcher. The empirical material includes transcripts from group conversations, data from teacher inquiry conducted within the project, and transcripts from follow-up interviews. The teachers’ aspirations can be understood as strivings to reinforce the connection between musical practices and various forms of human flourishing such that music and flourishing can sustain each other. Examples from their practices show how the word ‘good’ receives its meaning in context. Central among the teachers’ concerns is their hope that students develop a free and sustainable interest in music, often described as inspiration. I propose that ‘good relationships to music’ and ‘inspiration’ can be understood as philosophical mediators which support the transition from an indeterminate ‘interest in music’ towards specific ways in which music can become a (co-)constitutive part of living well in each person’s particular circumstances. Different musical practices emphasise different aspects of what is considered important in music and in human life. Music school teachers consciously balance between a variety of such values. They also make efforts to resist pressure which might threaten the goods they think are most important. Such goods include joy, participation, perseverance, solid musical skills related to specific practices, and a strong sense of vitality. The insights from this study suggest that when teachers are able to create inspiration, they seem to do so by performing complex work which combines musical and educational aims and makes general positive contributions to their students’ lives. Ensuring that teaching and learning in music schools remain as constructive and meaningful as possible for both students and teachers is a demanding task. The study indicates that collaborative, reflective and interdisciplinary work may be helpful as support for development processes on both individual and collective levels of music school teacher practices.

La música a la ciutat de Girona (1888-1985)

La tesi és una investigació histórica que presenta el fet musical a la ciutat de Girona, i inclou una paronòmica general de la història musical de les principals poblacions de les seves comarques: Olot, Figueres, Banyoles. ripoll, La Bisbal d'Empordà, Sant Feliu de Guíxols, etc. Està organitzada metodològicament en un marc cronològic i una metodologia positivista, intentant reflexar la verdadera història de la música a la ciutat de Girona amb tots i cadascun dels seus personatges i les seves institucions. La recerca s'emmarca al voltant de les corrents artístiques i polítiques de cada moment: Modernisme, Noucentisme, República, Guerra Civil, Franquisme i Democràcia. De cadascuna d'ella s'ha investigat sobre les orquestres, les cobles i les sardanes, els grups de música de cambra, la música en els cafès, la música en la intimitat de les cases particulars, el desenvolupament laboral de la professió musical a travès de la història del Sindicat i la Mútua de Músics, les sales de ball, els cinemes amb música en directe, els crítics musicals, etc. La recerca porta a la conclusió final de què l'època de millor esplendor, de més qualitat i també quantitat de música a la ciutat i comarques, i que ha viscut un millor ambient musical en tota la història, és el període que va des de principis del segle XX fins a l'esclat de la Guerra Civil (1900-1936)

Putting the P in Ptilotus: a phosphorus accumulating herb native to Australia

Background and Aims Ptilotus polystachyus (green mulla mulla; ptilotus) is a short-lived perennial herb that occurs widely in Australia in arid and semi-arid regions with nutrient poor soils. As this species shows potential for domestication, its response to addition of phosphorus (P) and nitrogen (N) was compared to a variety of the domesticated exotic perennial pasture herb Cichorium intybus (chicory), ‘Puna’. Methods Pots were filled with 3 kg of an extremely nutrient-deficient sterilized field soil that contained 3 mg kg−1 mineral N and 2 mg kg−1 bicarbonate-extractable P. The growth and P and N accumulation of ptilotus and chicory in response to seven rates of readily available phosphorus (0–300 mg P pot−1) and nitrogen (N) (0–270 mg N pot−1) was examined. Key Results Ptilotus grew extremely well under low P conditions: shoot dry weights were 23, 6 and 1·7 times greater than for chicory at the three lowest levels of P addition, 0, 15 and 30 mg P pot−1, respectively. Ptilotus could not downregulate P uptake. Concentrations of P in shoots approached 4 % of dry weight and cryo-scanning electron microscopy and X-ray microanalysis showed 35–196 mm of P in cell vacuoles in a range of tissues from young leaves. Ptilotus had a remarkable tolerance of high P concentrations in shoots. While chicory exhibited symptoms of P toxicity at the highest rate of P addition (300 mg P pot−1), no symptoms were present for ptilotus. The two species responded in a similar manner to addition of N. Conclusions In comparison to chicory, ptilotus demonstrated an impressive ability to grow well under conditions of low and high P availability. Further study of the mechanisms of P uptake and tolerance in ptilotus is warranted.

A música e a cidade: práticas sociais e culturais na cena da canção popular em Belém do Pará na década de 1980

A dissertação aborda o desenvolvimento de práticas de sociabilidade e de uma rede de compromissos entre os atores sociais integrantes do mundo artístico (BECKER, 1982) ensejadas por meio da canção popular, bem como formas de produção e circulação dessa mercadoria cultural na cidade de Belém do Pará, entendendo-a como uma área de fronteira (HANNERZ, 1997) nos anos oitenta. Para isso, recorri à categoria cena musical (STRAW, 1991) como subsídio para análise dessas ocorrências socioculturais. Trata-se de um estudo antropológico com temática histórica (FREHSE, 2005; SAHLINS, 1999) pautado em pesquisas em registros escritos e na oralidade que está dividido em três capítulos. O primeiro, intitulado "Uma cidade em expansão e sua cultura musical em processo" apresenta uma caracterização das transformações no cenário urbano de Belém do Pará no início da década de 1980 e as fundações de uma cena de canção popular. Assim, são estudados dois eventos fundamentais para a conformação desse cenário musical, a Feira Pixinguinha em Belém do Pará e o Projeto Jayme Ovalle. O segundo capítulo é "A produção da canção identitária pelas práticas discursivas de artistas da música popular na Belém dos anos 80". Nele são objetos a relação do lugar com a feitura da canção e seus significados, a ideia de canção como objeto-valor, a formação da associação de músicos CLIMA e o estudo de algumas canções emblemáticas da cena oitentista. O terceiro capítulo, “Práticas de sociabilidade e os 'lugares da canção’ na Belém do Pará oitentista” estuda os espaços sociais da canção popular como os lugares onde se produzia e consumia a essa mercadoria cultural e por onde circulavam artistas e público dessa modalidade musical na cidade - como bares, teatros, casas de show - sob as características do ambiente urbano local. Também, apresenta-se uma visada sobre os festivais da canção e as gravações como mercadoria cultural e lugar de projeto (VELHO, 2008) para a categoria dos artistas do cenário da música abordado.

Music tempo's effect on exercise performance: comment on dyer and mckune

Dyer and McKune (2013) stated that music tempo has no influence on performance, physiological, and psychophysical variables in well-trained cyclists during high intensity endurance tasks. However, there are important limitations in the methodology of the study. The participants'music preferences and tempo change were not well measured. It is not possible to affirm that music tempo does not influence athletes'performance. Potential areas of future research include: (a) use of instruments to assess the qualities of music; (b) standardizing music of tempo according to exercise type (e.g., running, cycling, etc.); (c) considering training level of the participants (i.e., athletes and non-athletes); and (d) use of instruments to assess concentration during exercise.

The effectiveness of Alexander Technique on music performance and musicians’ health and well-being – a systematic review

Introduction Musicians often suffer injuries related to their music playing. Therefore, some use Alexander Technique (AT), a mental-physical method that facilitates to release unnecessary muscle tension and to re-educate non-beneficial movement patterns through enhanced kinaesthetic awareness. According to a recent review AT may be effective for chronic back pain [1]. This review aimed to evaluate the evidence for the effectiveness of AT lessons on music performance and musicians’ health and well-being. Methods The following electronic databases were searched up to July 2012 for relevant literature: PUBMED, Google Scholar, CINAHL and EMBASE. The search criteria were "Alexander technique" AND "music*" [all fields]. References were searched, and experts and societies of AT or musicians' medicine contacted for further publications. Results 100 studies were identified. 24 studies were included for further analysis, 5 of which were randomised controlled trials (RCTs), 5 controlled but not randomised (CTs), 5 without control group, 2 mixed methods (RCT and case studies), and 7 surveys. 13 to 72 musicians participated per RCT. In 5 RCTs AT groups received between 12 and 20 one-to-one lessons. In 4 RCTs control groups received no interventions. Primary outcomes were performance anxiety, music performance, "use" as well as respiratory function and pain. Performance anxiety decreased by AT in 3 of 4 RCTs and in 3 of 3 CTs. Music performance was improved by AT in 1 RCT, yet in 2 RCTs comparing neurofeedback (NF) to AT, only NF showed improvements. Discussion and Conclusion To investigate the effectiveness of AT in musicians a variety of study designs and outcome measures have been used. Evidence from RCTs suggests that AT may improve performance anxiety in musicians. Effects on music performance, body use and respiratory function yet remain inconsistent. Future trials with scientifically sound study designs are warranted to further and more reliably explore the potential of AT as a relatively low cost and low risk method in the interest of musicians.
