Resumo

In the context of a preview of central topics taken from a larger research work, this article presents and explains a proposition of a functional analytical symbology which is currently being developed as a tool for the structural harmonic analysis of tonal music. This symbology constitutes a key component for a proposal of an analytical methodology for 19th-century extended tonality, which is the core of the aforementioned larger research work. Based on a critical revision of the history of music theory and analysis, this methodology is mainly the result of the recasting and the amplification of thoughts and concepts developed by 19th-century theorists such as Hugo Riemann and Arthur von Oettingen. The article introduces the proposed analytical symbology through a comparison to its historical counterparts, and it also highlights the ability of the proposed symbols to graph the harmonic language of 19th-century extended tonality by means of a few analytical examples.
