Abstract: Hierarchical and reductive analyses are central methods for music modeling and anaysis. However, to this day, no dedicated software exists to support analysts with this task. Here, we present a prototype of a generic tool for hierarchical analysis of scores in the Music Encoding Initiative (MEI) format. We use the rendering engine Verovio to render an MEI XML structure to a Scalable Vector Graphics (SVG) which is presented to the user. By selecting and manipulating the SVG elements using the tool, we add hierarchical analysis metadata to the MEI following the scheme proposed by Rizo and Marsden. We hope this tool will support professionals in performing hierarchical music annotations as well as find use in educational contexts.
