Abstract(s)
A arte organística surge por vezes isolada na História, mas percorre na realidade um caminho com múltiplos cruzamentos, aproximações e afastamentos a outras áreas do saber. O objetivo deste trabalho é estudar e estabelecer pontes entre as diferentes áreas científicas e artísticas que integram o restauro do órgão da Igreja de Santa Clara, a caracterização acústica do espaço e a sua gravação para arquivo.
A identificação e qualificação, das principais características históricas da organaría Ibérica, da Igreja de Santa Clara e do seu órgão basearam-se numa revisão bibliográfica focalizada. A caracterização acústica do instrumento e do espaço envolvente foi obtida por meio de testes acústicos realizados para determinação de parâmetros objetivos, como o Tempo de Reverberação e a Inteligibilidade da Palavra. A gravação sistemática,
e criteriosa de todas as notas produzidas pelos vários registos do instrumento permitiu a sua exata descrição sonora no presente, e constitui material essencial para a futura criação e programação de um instrumento virtual.
The art of Organ Building although occasionally isolated in History description, actually follows a path with multiple crossings and deviations with other scientific and artistic areas of knowledge development. This project aims to translationally study the organ of the Santa Clara’s church in Porto (Portugal): from its restoration to the acoustic characterization of the organ and its environment and, ultimately, its sound recording and archive to integrate a sound library. The identification and classification of the main historical characteristics of the Iberian Organ Building, Santa Clara’s Church and its organ were based on focused literature review. The acoustic characterization of the instrument and the space around it were obtained by acoustic tests carried out to determine objective parameters, such as Reverberation Time and Speech Transmission Index. The recording of all the notes produced by the various organ’s stops were systematic and judicious allowing the exact sound description of the instrument in the present and support essential material to the future creation and programming of a virtual instrument.
