Nos últimos anos, o violão vem progressivamente ganhando espaço qualitativo e quantitativo em pesquisas e publicações científicas da área musical. No Brasil, de modo especial, este crescimento tem encontrado ressonância em uma plêiade de pesquisadores(as) que pautam o instrumento em suas mais diversas abordagens. Coadunando-se a este movimento, a Revista Vórtex lança o Dossiê “Homenagem a Sérgio Abreu: violão, contextos, práticas e personagens”, encorajando a submissão de trabalhos que estejam relacionados direta ou indiretamente às atuações do homenageado como músico, transcritor ou luthier, tanto no que tange às suas relações com personagens, práticas e/ou contextos socioculturais mais amplos quanto na abordagem analítica de seus trabalhos solo, camerísticos, estilísticos, criativos e/ou de construção.

Este artigo apresenta a catalogação dos violões construídos pelo renomado luthier brasileiro Sérgio Abreu. O catálogo foi desenvolvido por meio de uma pesquisa documental, utilizando os livros de encomendas do próprio luthier, bem como uma pesquisa de campo realizada nas redes sociais, que envolveu a coleta de depoimentos de músicos e proprietários dos violões Abreu. O objetivo principal desta pesquisa é documentar e preservar o legado do construtor, destacando sua importância tanto no cenário nacional quanto internacional, e fornecer uma visão abrangente dos instrumentos por ele criados e seus métodos de produção. Através desse estudo, é possível compreender a significância de Sérgio Abreu para as práticas musicais, a luteria e a cultura do violão de concerto como um todo. Este trabalho representa um passo inicial na documentação desse legado, e espera-se que sirva como base para pesquisas futuras, visando ampliar e aprofundar o conhecimento sobre a obra desse renomado luthier.

O brasileiro Sérgio Abreu (1948-2023) ficou conhecido como concertista internacional ao violão, nas décadas de 1960 e 1970, inicialmente no Duo Abreu, formado com seu irmão, Eduardo, e depois em uma breve carreira solo. Na sequência, a luteria firmou-se como sua principal atividade. Há menor atenção quanto a Sérgio Abreu na produção musical e, devido a isso, o presente texto tem como objetivo principal evidenciar qual foi sua experiência e contribuição de produtor junto a dois quartetos, o Quaternaglia e o Brazilian Guitar Quartet. O método histórico tentou se cercar de elementos que mostrassem as condições em que os dois grupos surgiram e o momento em que Sérgio Abreu foi procurado. De referenciais, utilizamos Morais (2007) que estudou transcrições de Sérgio Abreu, o livro biográfico de Dias (2015), revistas especializadas, coleta de dados em páginas dos grupos e contatos com integrantes dos quartetos, obtendo-se relatos especialmente para esse artigo.

Quando pensamos em encontrar tesouros, pensamos em uma longa jornada onde no fim encontram-se coisas valiosas escondidas e inatingíveis. Mas, às vezes, os tesouros estão bem na nossa frente, no primeiro passo da jornada. Esse é o caso quando lemos o livro "Rhythmic Mastery" de Alice Artztz. Em seu livro, encontramos um mapa do tesouro na terceira página, a página de agradecimentos. Nossa guia, Alice Artzt, nos instrui: "Gostaria de agradecer a Sergio Abreu por seus extensos conselhos durante a escrita deste livro e por sua inestimável colaboração no Prólogo." Assim temos o prólogo "Algumas Reflexões sobre o Ritmo", escrito por Alice Artztz e Sergio Abreu. Ali está o nosso tesouro, logo no início deste grande livro. E tal tesouro cultural deve ser trazido à luz e compartilhado. Essa é a razão de traduzir O prólogo para o português.

Population growth and technology development are increasing rapidly. These cause the use of energy on the earth is increasing. One effort to obtain energy sources is to utilize solar energy using solar water heater. This research was expected to help the society to save energy derived from fossils. A testing was conducted by designing solar water heater with collector size of 60 cm x 50 cm using black painted aluminum-coated styrofoam insulator and the storage tank made of stainless steel with volume of 40 liter using black painted aluminum-coated styrofoam. In conducting the testing, the data were taken at 09.00 a.m until 04.00 p.m for 5 days. The research was conducted at ITD Adisutjipto.
