Algorithmic Thinking, Analysis and Visualization in Music (ATAVizM) (Public Lecture or Presentation)
Title: Algorithmic Thinking, Analysis and Visualization in Music (ATAVizM)
Abstract: A primary learning outcome in music theory courses is the ability to analyze musical form. To improve undergraduate music education, we have developed a combination of novel data pre-processing and user-directed pattern finding that make it possible to reach the full potential of Martin Wattenberg’s 2001 vision for seeing the "Shape of Song" ( Through the ATAVizM course module, students create compelling visualizations to accompany their analytical papers, but more importantly they learn how analytical processes may be implemented as algorithms. Musical themes and motives are often transposed or otherwise modified in the course of a piece. An example is the subject and answer of a fugue (an imitative polyphonic composition). How do we formalize the relationship between a subject and tonal answer? Or, the improvisational “licks” of Dizzy Gillespie? Such that we could define “themes” as a category that may be formalized computationally? Especially, when a computer does not know where to look for themes or what modifications to expect? We discuss how algorithms informed by humanistic understanding of music can work much better than those that are not.

Tone Realization and Register Transformations in Nigerian Art Music: A formal analysis of Èkwúèmé and Olúrántí (Article)
Title: Tone Realization and Register Transformations in Nigerian Art Music: A formal analysis of Èkwúèmé and Olúrántí
Author: Aaron Carter-Enyi
Abstract: Since J. J. Ransome Kuti in 1923, Nigerian composers have carefully considered and developed the art of setting texts in Niger-Congo tone languages to music. Writings on the compositional process of Nigerian composers includes both early contributions by Phillips (1952) and Èkwúèmé (1974) to recent contributions by Euba (2001) and Olúrántí (2012). Ethnomusicologists and linguists have also provided theory and analysis on the topic but have conventionally limited their analysis to adjacent contour comparisons and traditional and popular music. This article considers these three strands of literature on the subject of “tone and tune” and applies formal analytical methods for studying musical scores by living Nigerian art composers. Special attention is paid to two secular choral compositions based on indigenous proverbs, “Obi Dimkpa” (1980) by Laz Èkwúèmé and “Ọmọlúàbí” (2018) by Ayọ̀Olúrántí. Together, these works illustrate the relevance of contour and transformational theory to highly articulate settings of tone language texts.
