La improvisació musical, sota el microscopi.

UNA DE LES FORMES MÉS COMPLEXES de comportament creatiu és la improvisació musical, tan típica d'alguns estils com el jazz i el freestyle rap, però que tanmateix es pot aplicar a qualsevol estil, des de la música clàssica fins al rock'n'roll, passant per la música tradicional. Roger E. Beaty, de la Universitat de Carolina del Nord, als EUA, ha publicat un treball a Neuroscience and Biobehavioral Reviews on compara l'activitat neural durant la improvisació musical en músics de diferents estils. Els resultats indiquen que els processos mentals seguits per uns i altres no són exactament els mateixos, i que les principals diferències es troben en la predominança de control cognitiu durant la improvisació o alternativament de pensament divergent.

Educación musical intercultural a través de un proyecto europeo Comenius y su aportación a las competencias básicas

La experiencia se enmarca en un proyecto de intercambio Comenius desarrollado entre los años 2002-2005, con la participación de seis centros europeos. A partir de la asignatura de prácticas de los alumnos de la Universidad de Girona, se ha implicado la educación musical en el proyecto y se ha desarrollado, a lo largo de tres cursos, una rica experiencia intercultural a través de la canción, la danza y la composición. A su vez, se analizan las aportaciones del proyecto al trabajo de las competencias básicas de la etapa

Entornos e-learning como soporte de aprendizaje a la asignatura educación musical en infancia

The music is a compulsory subject in the first stage of primary education. We detected several teachers from different educational areas, including the area of music, using e-learning platforms and web tools for teaching the curriculum that marks the “Department of Education of the Generalitat de Catalunya”. From the body of analysis has drawn the picture in e-learning platforms, analyzing the types and uses. Through the sample of e-learning platforms in music education, have identified four schools with e-learning platforms in advanced stage. We performed a case study on one of these platforms for content analysis and validate the interview format used; this has served to create a model that can be used in other centers with e-learning platform for music subject.

The Connectivity of Musical Aptitude and Foreign Language Learning Skills: Neural and Behavioural Evidence

Given the structural and acoustical similarities between speech and music, and possible overlapping cerebral structures in speech and music processing, a possible relationship between musical aptitude and linguistic abilities, especially in terms of second language pronunciation skills, was investigated. Moreover, the laterality effect of the mother tongue was examined with both adults and children by means of dichotic listening scores. Finally, two event-related potential studies sought to reveal whether children with advanced second language pronunciation skills and higher general musical aptitude differed from children with less-advanced pronunciation skills and less musical aptitude in accuracy when preattentively processing mistuned triads and music / speech sound durations. The results showed a significant relationship between musical aptitude, English language pronunciation skills, chord discrimination ability, and sound-change-evoked brain activation in response to musical stimuli (durational differences and triad contrasts). Regular music practice may also have a modulatory effect on the brain’s linguistic organization and cause altered hemispheric functioning in those who have regularly practised music for years. Based on the present results, it is proposed that language skills, both in production and discrimination, are interconnected with perceptual musical skills.

Gens,humans i rock

El rock'n'roll, un dels estils musicals més influents del segle XX, es va gestar als EUA durant la dècada de 1940 a partir del blues, el rhythm'n'blues i el country. Joel vaig descobrir de forma conscient el 1979, quan tenia 14 anys. I el seu ritme em va captivar tant les neurones que continua sent el meu estil musical predilecte, amb el qual identifico bona part de les meves emocions.

Chemical composition, circadian rhythm and antibacterial activity of essential oils of piper divaricatum: a new source of safrole

The essential oils from leaves, stems and fruits of Piper divaricatum were analyzed by GC-MS. The tissues showed high safrole content: leaves (98%), fruits (87%) and stems (83%), with yields of 2.0, 4.8 and 1.7%, respectively. This is a new alternative source of safrole, a compound widely used as a flavoring agent and insecticide. The leaf's oil showed antibacterial activity against gram-negative bacteria while safrole was active against Salmonella Typhimurium and Pseudomonas aeruginosa. In addition, the study of circadian rhythm of the safrole concentration in the essential oils of leaves showed a negligible variation of 92 to 98%.

Comparison Structure Analysis

This study presents an automatic, computer-aided analytical method called Comparison Structure Analysis (CSA), which can be applied to different dimensions of music. The aim of CSA is first and foremost practical: to produce dynamic and understandable representations of musical properties by evaluating the prevalence of a chosen musical data structure through a musical piece. Such a comparison structure may refer to a mathematical vector, a set, a matrix or another type of data structure and even a combination of data structures. CSA depends on an abstract systematic segmentation that allows for a statistical or mathematical survey of the data. To choose a comparison structure is to tune the apparatus to be sensitive to an exclusive set of musical properties. CSA settles somewhere between traditional music analysis and computer aided music information retrieval (MIR). Theoretically defined musical entities, such as pitch-class sets, set-classes and particular rhythm patterns are detected in compositions using pattern extraction and pattern comparison algorithms that are typical within the field of MIR. In principle, the idea of comparison structure analysis can be applied to any time-series type data and, in the music analytical context, to polyphonic as well as homophonic music. Tonal trends, set-class similarities, invertible counterpoints, voice-leading similarities, short-term modulations, rhythmic similarities and multiparametric changes in musical texture were studied. Since CSA allows for a highly accurate classification of compositions, its methods may be applicable to symbolic music information retrieval as well. The strength of CSA relies especially on the possibility to make comparisons between the observations concerning different musical parameters and to combine it with statistical and perhaps other music analytical methods. The results of CSA are dependent on the competence of the similarity measure. New similarity measures for tonal stability, rhythmic and set-class similarity measurements were proposed. The most advanced results were attained by employing the automated function generation – comparable with the so-called genetic programming – to search for an optimal model for set-class similarity measurements. However, the results of CSA seem to agree strongly, independent of the type of similarity function employed in the analysis.

Real-time Musical Pair Improvisation on Mobile Devices

This thesis discusses the design and implementation of a real-time musical pair improvisation scenario for mobile devices. In the scenario transferring musical information over a network connection was required. The suitability of available wireless communication technologies was evaluated and communication was analyzed and designed on multiple layers of TCP/IP protocol stack. Also an application layer protocol was designed and implemented for the scenario. The implementation was integrated into a mobile musical software for children using available software components and libraries although the used platform lead to hardware and software constraints. Software limitations were taken into account in design. The results show that real-time musical improvisation can be implemented with wireless communication and mobile technology. The results also show that link layer had the most significant effect on real-time communication in the scenario.

Musikalisk lärandemiljö : planerade musikaktiviteter med småbarn i daghem

A musically stimulating nvironment is of great significance when considering the opportunities for development and learning that are offered to children in day nurseries. Moreover, the quality of musical activities also has great significance for the musical development of growing children. Young children are always striving to create meaning and understanding; they influence and are influenced by the context in which they are situated. The purpose of this study is to investigate the planned music activities in the musical learning environment of seven toddler’s groups in day nurseries, based on four different aspects: the texts of children’s songs, the melodies of children’s songs, the basic elements of music and the use of instrumentation. The data has been gathered by video observation of the planned music activities. The age of the children studied ranged from 11 months to 3 years and 11 months, and on average there were 13 children in each group. The study involved a total of just over 90 children and nine educators. The methodological approaches are hermeneutic as well as videographic, and they are applied to the analysis as required. The approaches are well suited to an understanding of the planned music activities where the individual’s communications and actions are studied. The results of the study show that educators impart a cultural heritage to the children in the form of old traditional songs, but they also act as intermediaries for newer children's songs. They focus on actively on the text content of the children’s songs in their interaction with the children, but do not address the meaning of the text. Furthermore, while the educators use music sessions for the children to develop, among other things, an understanding of language and social skills, they do not use the sessions to develop the children’s musical skills. The educators could, to a much greater extent than they now do, direct the children's attention to the basic elements of music, and conduct meta-cognitive dialogues with the children. They use a large repertoire of children's songs, which are, however, often too demanding for the children’s voices to cope with. In addition, the educators do not plan, in any significant way, activities for the toddlers in order to help them develop the accuracy of their vocal tones. With regard to the use of instruments, the educators focus, in their interaction with the children, is placed on both the usage of the instruments and knowledge about the instruments. Regarding the use of instruments the study shows that the children’s musical expression takes place in an environment that includes both melody and rhythm instruments. It is clear that children are actively interested in the constructed instrument environment, because for long periods of time they independently play and experiment with instruments.
