THE CHORD WHEEL DIAGRAM: A VISUAL FRAMEWORK FOR GUITAR HARMONY SUPPORTED BY BPMN

Popis výsledku v původním jazyce

This paper introduces a novel type of interactive visual aid, the “chord wheel diagram,” designed to support the teaching of triad and seventh chord construction within a given key. In contrast to the well-known circle of fifths and fourths, which primarily illustrates relationships between keys, our chord circle is a tool for building chords within a key. It enables users to visualize chords built from each degree of a selected tonality, including their component tones. Our teaching approach focuses on the six-string guitar in standard tuning (E–A–D–G–B–E), and chords are presented using standard fretboard diagrams, providing students with both a visual and kinesthetic representation of chord shapes. A key contribution of this work is developing a process model for chord construction using BPMN (Business Process Model and Notation), which formalizes the algorithmic logic behind generating playable chord shapes from input notes. To make this method accessible and practical, we developed the web application aakordy.cz, which offers an interactive chord wheel and diagram, real-time fretboard visualization, and validation of chord composition. The article also presents qualitative evaluation data from respondents who used the tool during guitar instruction. Our findings show that integrating visual and process-based models significantly enhances understanding of tonal relationships and chord structure. This contributes to more effective learning in music theory and instrumental practice.
