- Reflections on Linda Bustani’s piano methodologyPublication . Cannoud, Fernanda; Castilho, M.L.C.This article’s context is that of specialized teaching of piano music teaching (individual and group), at beginner, basic and professional levels. Considering the peculiarities of each location, we felt the need to record the applicability of the piano teaching methodology of Linda Bustani (1951-) with whom we studied directly. This methodology was published in a book entitled Falando de Piano com Linda Bustani e Luiz Eça [Speaking of Piano with Linda Bustani and Luiz Eça] by Moema Campos. It consists of basic work on the piano, which can be compared to that of a ballerina on the barre. According to Bustani, the trained hand prepares the pianist to achieve full technical mastery and thus be qualified for musical interpretation (Campos, 2017). Linda Bustani's piano teaching methodology, systematized in this article, has been applied by her since 1980 in Brazil, with significant success. Since the 2000s, we have developed this pedagogy as a piano teacher, applying it with students of different ages. We are currently working in Portugal, and we wonder if Linda Bustani's pianistic methodology has similarities with the approach used by teachers in Portugal. To this end, we developed a qualitative descriptive study, which used as data collection instruments, in addition to bibliographical and documentary research, a questionnaire survey to piano teachers. The results point to a similar pedagogical approach used by teachers, despite not knowing Linda Bustani's methodology.
- What does sound look like? Musical iconography in the quilts of Castelo BrancoPublication . Castilho, M.L.C.Castelo Branco embroidery, which is closely linked to quilts, has become the “ex-libris” of the city and one of the most important aspects of its cultural identity and heritage. A rich variety of motifs are embroidered in natural silk on linen, using an established design as a guide. This article aims to analyze and characterize the motifs that suggest sound — the sounds of animals, the environment, and musical instruments.
- Teatro, Música e Cinema: The musical instruments in the decorative mural tapestry in the hall of the Teatro-Cine da CovilhãPublication . Luiz, Carlos Santos; Castilho, M.L.C.; Duarte, Sónia; Sousa, CláudiaOn May 31, 1954, the Teatro-Cine da Covilhã, nowadays called Teatro Municipal da Covilhã (Portugal), was inaugurated. In the entrance hall, on the wall of the staircase, a tapestry called Teatro, Música e Cinema, by Tapetes de Portalegre Lda., today called Manufatura de Tapeçarias de Portalegre, has been displayed since the opening day. As a large tripartite mural tapestry, the work is a reproduction of a cartoon, a manual technique, which had as its starting point an original by an artist. This is João Tavares (1908-1984), painter, watercolourist, draftsman, and teacher at the Liceu de Portalegre. The tapestry we will study has several musical and dance motives in dialogue with other arts, like the Theatre (with allegorical representations of a stage, a scenario, and male and female figures), Music (musical instruments or a female figure linked to mousiké) and the Cinema (with allegorical representations of a horse or a star with luminous rays or a cinema reel). As for the musical instruments, these appear to have references to elements from Classical Antiquity that extend to other later temporal landmarks. Finally, this chapter aims to disseminate the study of the Teatro, Música e Cinema tapestry in a holistic way. Thus, the tapestry was described and analysed from an iconographic and iconological point of view, addressing João Tavares' aesthetic choices, as well as the historical and acoustic aspects of the Teatro-Cine da Covilhã.
- The conception of stories as a stories for piano teaching and learning: Relationships between musical elements and extra-musical elementsPublication . Pires, Rita; Castilho, M.L.C.The relation between music and emotions has been a topic of several studies in the last two decades. We tried to find strategies that would help encourage students on piano learning, especially the youngest ones. The strategy of finding relationships between musical elements and extra-musical elements can be a way to emotionally involve the students in the music. In an experiment, we asked two twelve year old piano students to create stories based on two musical pieces that were being studied by them. The aim of the present article is to search relationships between elements of the musical pieces and the extra-musical elements of the stories. We could observe how certain musical structures (such as dynamics, articulation, and others) can influence the thought and emotions of the students.
- Análise e avaliação de algoritmos para reconhecimento de posturas com base em matrizes de pressãoPublication . André Carvalho Serra; Ribeiro, Fernando Reinaldo Silva Garcia Ribeiro; Metrôlho, José Carlos Meireles Monteiro2025O processo de controlar e monitorizar o estado do paciente durante as suas horas de sono tem vindo a ajudar no estudo de diminuição de riscos de saúde, nomeadamente em situações nas quais os maus hábitos noturnos ou mau posicionamento do corpo causam diferentes tipos de problemas no seu respetivo bem-estar. Vários estudos têm sido feitos neste âmbito, nomeadamente para a classificação de posturas das pessoas que se encontram acamadas, cada um deles seguindo diferentes abordagens. Por exemplo, técnicas que utilizam matrizes de pressão obtidas de sensores posicionados sobre o colchão, juntamente com algoritmos de machine learning (ML), têm alcançado precisões de até 99% (e.g., [1]) na classificação das posturas principais (virado para cima, virado para baixo, lateral esquerdo e lateral direito). Este trabalho centra-se na utilização de algoritmos de ML aplicados a dados obtidos por uma matriz de sensores de pressão posicionada por baixo do colchão, de forma a minimizar o desconforto para o paciente monitorado. Usando este conjunto de dados, são aplicados e avaliados algoritmos para a classificação das posturas principais e as suas variações, com o objetivo de desenvolver uma solução eficaz e menos invasiva para monitorização da postura. Os experimentos incluíram 10 algoritmos de ML, que alcançaram uma accuracy média entre 79,14% e 98,93% com validação Group K-Fold e entre 80,03% e 97,14% com a técnica Leave-One-Group-Out (LOGO) para classificar as quatro posturas principais. O estudo também expandiu a classificação para 28 variações de postura (7 variações para cada postura principal), com o algoritmo SVM alcançando uma accuracy de 65,18% na validação Group K-Fold. Isso representa uma melhoria significativa em relação a estudos anteriores, especialmente ao considerar o maior número de posturas. Comparações com outras abordagens que utilizam sensores de pressão mostram que esta solução, com sensores posicionados por baixo do colchão, oferece uma accuracy comparável e, em alguns casos, superior. Esses resultados sugerem que o uso de sensores por baixo do colchão é uma alternativa eficaz e menos intrusiva para a classificação de posturas.
- Advanced classification of Brazilian stingless bee honey by genus using comprehensive analytical techniques and chemometricsPublication . Ressutte, Jéssica; Galvan, Diego; Luz, Cynthia F.P. da; Gonçalves, Ana Margarida; Rebelo, Kemilla S.; Sattler, José Augusto G.; Passarinha, Luis A.; Gallardo, Eugenia; Anjos, O.; Spinosa, Wilma A.This study aimed to investigate Brazilian stingless bee honey (SBH) to compare their chemical compositions. Fifty-five samples from the genera Melipona, Scaptotrigona, Frieseomelitta, Tetragona, and Tetragonisca, collected from five regions were evaluated by melissopalynological and physicochemical analysis, phenolic compounds, sugar profiling, and FTIR-ATR. Multiblock Analysis (MA) was employed to discriminate and assess the influence of entomological (bee genus) and geographical origins on the honey's characteristics. Subsequently, Linear Discriminant Analysis (LDA) and Partial Least Squares Discriminant Analysis (PLS-DA) were employed to classify the samples based on quantitative data and FTIR-ATR spectra, respectively. The primary factor influencing the chemical profile of Brazilian SBH was entomological origin. MA partially separated samples, while LDA and PLS-DA effectively predicted Melipona, Scaptotrigona, and Tetragonisca samples. Key parameters for separation using MA included sugar profile, phenolic compounds, and FTIR-ATR regions (1800–750 cm⁻¹). In the LDA model, electrical conductivity, pH, color (a*), raffinose content, reducing sugars, and trehalulose + maltose were key for classification. For PLS-DA, spectral regions 1610–1557 cm⁻¹ , 1126–960 cm⁻¹ , and 1170–915 cm⁻¹ were critical for distinguishing samples. This study enhances the understanding of how entomological and geographic factors influence Brazilian SBH characteristics and supports its traceability for quality and authenticity.

- Ratinhos, Musical iconography and popular culture: 19th-Century Faience from the Manuel Cargaleiro FoundationPublication . Castilho, M.L.C.; Rocha, LuziaThe words ratinho(s)/ratinha(s) designates the Beirã population (from the northeast Portugal) who moved seasonally to Alentejo (southeast Portugal) to carry out agricultural work. The lack of work opportunities combined with the needs of the poorest social classes from the Beiras region dictated these migratory movements. It was the name ratinhos that would be used to designate the faience made in Coimbra, which would represent these social types. The faience ratinha was characterized by its low cost, durability, and rich and appealing decoration. Such decoration includes the depiction of musicians mainly on plates. It is the aim of this chapter to analyze seven ratinho plates with musicians, from the Manuel Cargaleiro Foundation in Castelo Branco (Portugal). As such, the following research questions were asked: What musical instruments are represented? Who is playing? What is the gender and social classes of the performers? What are the iconographic models of this faience decoration? In this way, this research intends to fill a gap by providing a musicological study in an area that has not been addressed by the scientific community.
- The contribution of Dorothy Taubman’s approach to piano techniquePublication . Fernandes, Daniela; Castilho, M.L.C.; Fonte, VeraThis research intends to analyze how Dorothy Taubman’s approach contributes to the resolution of problems in piano technique, particularly in students at beginner level. The problematic of this study is based on the curiosity to explore new strategies that help students overcome technical difficulties, such as muscle tension or note articulation, while simultaneously developing a greater body awareness of the process that involves piano playing. Using action-research methodology, the study was founded on an analysis of the results obtained with two students at level III (of initiation) and three students at level IV, after applying eight exercises created according to the principles of Taubman’s approach. The following instruments were used to assist the data collection process: a lesson report, a lesson evaluation grid, a monthly evaluation table, two interviews and two recordings of each of the participants (before and after the intervention). The aim was to share them, along with the respective evaluation grids, with examiners not involved in the project, so that external opinions could be gathered. At the end of the research, it was possible to see progress in almost all the parameters evaluated, and it was also observed, through the interviews, that the students had developed a greater awareness of their body behavior and their technique.
