Lecture @ RWTH Aachen by Nikita Braguinski: Life-Like Artificial Music: Understanding the Impact of AI on Musical Thinking

Life-Like Artificial Music: Understanding the Impact of AI on Musical Thinking
June 5, 17:00-18:30
RWTH Aachen. Käte Hamburger Kolleg “Cultures of Research”
Theaterstraße 75, 52062 Aachen
Online participation is also possible: https://khk.rwth-aachen.de/event/evening-lecture-ss24-4/

This lecture explores the impact of machine learning on the future of music research and theory.  It argues that AI-generated music poses a deep challenge for existing theories: AI systems can  learn to imitate musical styles without receiving any information about human music theory concepts, raising questions about the validity of those concepts. Additionally, music-generating  AI systems can be trained on audio directly, bypassing notation, while human music theory  almost always works with notation as a simplified and abstracted proxy.

As an example of the conceptual challenges and shifts that now arise in music research, the talk  examines a recent paper that compares Western music theory concepts with structures that  emerge in a machine learning model trained on musical notation. While the paper finds  similarities between the two, the talk argues that the machine learning system’s output is still  influenced by human biases and choices in the training data and model architecture – and that  this influence may in fact be unavoidable.

Finally, the talk argues that while AI may be able to generate novel structures for analyzing
music, their applicability to human music theory and practice may prove to be extremely limited  due to the differences between human cognition and machine learning. Overall, the talk raises  questions about the future potential for AI to disrupt human theory-making – and not only in the  discipline of musicology.

No knowledge of musicological concepts is required for understanding the presentation and participating in the discussion.

Dr. Nikita Braguinski is a 2023-2024 Fellow at the Käte Hamburger Kolleg “Cultures of Research” at RWTH Aachen University. In his work he currently concentrates on the possible impact of machine learning and big online listening datasets on the future of music research. His book “Mathematical Music. From Antiquity to Music AI” (Routledge, 2022) was translated into Korean, receiving the Sejong book prize in 2023. He was a Fellow at Harvard University, a Visiting Scholar at the University of Cambridge, and a Researcher at Humboldt University of Berlin with funding from the Volkswagen Foundation. In 2023, he co-convened, together with Eamonn Bell and Miriam Akkermann, the ZiF Bielefeld Visiting Research Group “The Future of Musical Knowledge in the Age of Machine Learning”.

Call for Papers: TISMIR Special Collection on Multi-Modal Music Information Retrieval

TISMIR Special Collection on Multi-Modal Music Information Retrieval
(see also the PDF version on the TISMIR web page)

Deadline for Submissions
01.08.2024

Scope of the Special Collection
Data related to and associated with music can be retrieved from a variety of sources or modalities: audio tracks; digital scores; lyrics; video clips and concert recordings; artist photos and album covers; expert annotations and reviews; listener social tags from the Internet; and so on. Essentially, the ways humans deal with music are very diverse: we listen to it, read reviews, ask friends for recommendations, enjoy visual performances during concerts, dance and perform rituals, play musical instruments, or rearrange scores.

As such, it is hardly surprising that we have discovered multi-modal data to be so effective in a range of technical tasks that model human experience and expertise. Former studies have already confirmed that music classification scenarios may significantly benefit when several modalities are taken into account. Other works focused on cross-modal analysis, e.g., generating a missing modality from existing ones or aligning the information between different modalities.

The current upswing of disruptive artificial intelligence technologies, deep learning, and big data analytics is quickly changing the world we are living in, and inevitably impacts MIR research as well. Facilitating the ability to learn from very diverse data sources by means of these powerful approaches may not only bring the solutions to related applications to new levels of quality, robustness, and efficiency, but will also help to demonstrate and enhance the breadth and interconnected nature of music science research and the understanding of relationships between different kinds of musical
data.

In this special collection, we invite papers on multi-modal systems in all their diversity. We particularly encourage under-explored repertoire, new connections between fields, and novel research areas. Contributions consisting of pure algorithmic improvements, empirical studies, theoretical discussions, surveys, guidelines for future research, and introductions of new data sets are all welcome, as the special collection will not only address multi-modal MIR, but also cover multi-perspective ideas, developments, and opinions from diverse scientific communities.

Sample Possible Topics
● State-of-the-art music classification or regression systems which are based on several
modalities
● Deeper analysis of correlation between distinct modalities and features derived from them
● Presentation of new multi-modal data sets, including the possibility of formal analysis and theoretical discussion of practices for constructing better data sets in future
● Cross-modal analysis, e.g., with the goal of predicting a modality from another one
● Creative and generative AI systems which produce multiple modalities
● Explicit analysis of individual drawbacks and advantages of modalities for specific MIR tasks
● Approaches for training set selection and augmentation techniques for multi-modal classifier systems
● Applying transfer learning, large language models, and neural architecture search to
multi-modal contexts
● Multi-modal perception, cognition, or neuroscience research
● Multi-objective evaluation of multi-modal MIR systems, e.g., not only focusing on the quality, but also on robustness, interpretability, or reduction of the environmental impact during the training of deep neural networks

Guest Editors
● Igor Vatolkin (lead) – Akademischer Rat (Assistant Professor) at the Department of Computer Science, RWTH Aachen University, Germany
● Mark Gotham – Assistant professor at the Department of Computer Science, Durham
University, UK
● Xiao Hu – Associated professor at the University of Hong Kong
● Cory McKay – Professor of music and humanities at Marianopolis College, Canada
● Rui Pedro Paiva – Professor at the Department of Informatics Engineering of the University of Coimbra, Portugal

Submission Guidelines
Please, submit through https://transactions.ismir.net, and note in your cover letter that your paper is intended to be part of this Special Collection on Multi-Modal MIR.
Submissions should adhere to formatting guidelines of the TISMIR journal:
https://transactions.ismir.net/about/submissions/. Specifically, articles must not be longer than 8,000 words in length, including referencing, citation and notes.

Please also note that if the paper extends or combines the authors‘ previously published research, it is expected that there is a significant novel contribution in the submission (as a rule of thumb, we would expect at least 50% of the underlying work – the ideas, concepts, methods, results, analysis and discussion – to be new).

In case you are considering submitting to this special issue, it would greatly help our planning if you let us know by replying to igor.vatolkin [AT] rwth-aachen.de.

Two papers accepted for EvoMUSART 2024

(1) J. Dettmer, I. Vatolkin, and T. Glasmachers: Weighted Initialisation of Evolutionary Instrument and Pitch Detection in Polyphonic Music. Accepted for Proceedings of the 13th International Conference on Artificial Intelligence in Music, Sound, Art and Design (EvoMUSART)

Abstract: Current state-of-the-art methods for instrument and pitch detection in polyphonic music often require large datasets and long training times; resources which are sparse in the field of music information retrieval, presenting a need for unsupervised alternative methods that do not require such prerequisites. We present a modification to an evolutionary algorithm for polyphonic music approximation through synthesis that uses spectral information to initialise populations with probable pitches. This algorithm can perform joint instrument and pitch detection on polyphonic music pieces without any of the aforementioned constraints. Sets of tuples of (instrument, style, pitch) are graded with a COSH distance fitness function and finally determine the algorithm’s instrument and pitch labels for a given part of a music piece. Further investigation into this fitness function indicates that it tends to create false positives which may conceal the true potential of our modified approach. Regardless of that, our modification still shows significantly faster convergence speed and slightly improved pitch and instrument detection errors over the baseline algorithm on both single onset and full piece experiments.

(2) L. Fricke, M. Gotham, F. Ostermann, and I. Vatolkin: Adaptation and Optimization of AugmentedNet for Roman Numeral Analysis Applied to Audio Signals. Accepted for Proceedings of the 13th International Conference on Artificial Intelligence in Music, Sound, Art and Design (EvoMUSART)

Abstract: Automatic music harmony analysis has recently been significantly improved by AugmentedNet, a convolutional recurrent neural network for predicting Roman numeral labels. The original network receives perfect note annotations from the digital score as inputs and predicts various tonal descriptors: key, chord root, bass note, harmonic rhythm, etc. However, for many music tracks the score is not available at hand. For this study, we have first adjusted AugmentedNet for a direct application to audio signals represented either by chromagrams or semitone spectra. Second, we have implemented and compared further modifications to the network architecture: a preprocessing block designed to learn pitch spellings, increase of the network size, and addition of dropout layers. The statistical analysis helped to identify the best among all proposed configurations and has shown that some of the optimization steps significantly increased the classification performance. Besides, AugmentedNet can reach similar accuracies with audio features as inputs, compared to the perfect annotations that it was originally designed for.
