Significance in Portals and the Apse by Celso Loureiro Chaves

An analysis of the solo guitar piece Portals and the Apse by Celso Loureiro Chaves (1997) is undertaken in this article. The analysis follows the principles of the new musicology, as put into practice by authors such as Lawrence Kramer and Rose Subotnik. The starting point of the analysis and its guiding line are the evidences left behind by the composer, namely the entirely serial nature of the work; the relationship of its formal scheme with "the architectural plan of an imaginary temple, that could be located on Prospero's island as drawn by Peter Greenaway for his film Prospero's Books "; the reference of the central section of the work to the memory of a "distant reading of the novel The Devil to Pay in the Backlands, by Guimarães Rosa." From these evidences we seek to draw a context that aims at illuminating the work and unveiling the depth of its meaning.
