A musical performance can convey both the musicians’ interpretation of the written musical score as well as emphasize, or even manipulate, the emotional content of the music through small variations in timing, dynamics, tuning, and timbre. This talk presents my work on score-guided automatic musical performance analysis, as well as my investigations into vocal intonation practices and possible implications for composition practice. The score-audio alignment algorithm I developed to estimate note locations makes use of a hybrid DTW-HMM multi-pass approach that is able to capture onset and offset asynchronies between simultaneously notated chords in polyphonic music. My work on vocal intonation practices, motivated by exploring the range of extended tuning techniques available to vocalists, has examined both solo and ensemble singing, with a particular focus on the role of musical training, the presence and/or type of accompaniment, and the organization of musical materials on intonation.

Johanna Devaney is an assistant professor of music theory and cognition at The Ohio State University. Her research applies a range of interdisciplinary approaches to the study of musical performance, motivated by a desire to understand how performers mediate listeners’ experience of music. Her work on extracting and analyzing performance data, with a particular focus on intonation in the singing voice, integrates the fields of music theory, music perception and cognition, signal processing, and machine learning. She has released a number of the tools she has developed in the open-source Automatic Music Performance and Comparison Toolkit (www.ampact.org). Johanna completed her PhD in the Music Technology program at the Schulich School of Music of McGill University. She also holds an M.Phil. degree in Music Theory from Columbia University, as well as an MA in Composition from York University in Toronto. Before joining Ohio State, she was a postdoctoral scholar at the Center for New Music and Audio Technologies (CNMAT) at the University of California, Berkeley.
