00925njm 22002777a 4500 dc Martorell Domínguez, Agustín author Gómez Gutiérrez, Emilia, 1975- author 2020-11-16T12:00:23Z 2020-11-16T12:00:23Z 2015 This work presents a systematic methodology for set-class surface analysis using temporal multi-scale techniques. The method extracts the set-class content of all the possible temporal segments, addressing the representational problems derived from the massive overlapping of segments. A time versus time-scale representation, named class-scape, provides a global hierarchical overview of the class content in the piece, and it serves as a visual index for interactive inspection. Additional data structures summarize the set-class inclusion relations over time and quantify the class and subclass content in pieces or collections, helping to decide about sets of analytical interest. Case studies include the comparative subclass characterization of diatonicism in Victoria's masses (in Ionian mode) and Bach's preludes and fugues (in major mode), as well as the structural analysis of Webern's Variations for piano op. 27, under different class-equivalences.
