Abstract

This study continues construction of specialized grammars covering music information. The proposed grammar is searching-oriented and therefore largely simplified, in order to create easily-searchable structure. Searching is seen here as a particular querying operation in spaces of music information. Searching is discussed for patterns melodically and rhythmically transformed - with transformations in pitch and time dimensions typical for music works. Three operators are proposed to provide convenient meta-data for searching. Searching may be performed in both structured and unstructured musical pieces, regarding voice selection. Proposed methodology may serve for searching of transformed and non-transformed motives, searching of inspirations, comparative analysis of musical pieces, analysis of melodic and rhythmical sequences, harmonic analysis and structure discovery.
