1 Analysing Physiological Data Collected During Music Listening: An Introduction


Laura Bishop, University of Oslo

Geoffray Bonnin, Université de Lorraine

Jérémy Frey, Ullo


Music has diverse effects on listeners, including inducing emotions, triggering movement or dancing, and prompting changes in visual attention. These effects are often associated with psychophysiological responses like changes in heart activity, respiratory rate, and pupil size, which can themselves be influenced by the cognitive effort exerted during music listening, e.g., when engaging with unfamiliar tracks on a web radio for music discovery.

This tutorial aims to introduce psychophysiological data analysis for a broad MIR audience, with a particular focus on the analysis of heart rate, electrodermal activity and pupillometry data. It will be structured in three parts. The first part will provide a presentation of psychophysiological data that we collected in the context of a preliminary study related to music discovery. The second part will be a hands-on tutorial during which we will guide the participants to remake two of our data analyses. In the third part, we will assist participants in undertaking their own data analysis of our data. These analyses will be demonstrated using R and Python.

Our aim with this tutorial is twofold: to promote underrepresented topics in the MIR community, especially the recognition of induced emotions from physiological data and discovery-oriented music recommendation; and to encourage researchers from those domains to interact with the MIR community. The audience we target is therefore relatively large. Participants should, however, possess sufficient knowledge of R and/or Python and standard statistical analysis methods to participate in the hands-on parts of the tutorial.


Laura Bishop is a researcher at the RITMO Centre for Interdisciplinary Studies in Rhythm, Time and Motion and the Department of Musicology at the University of Oslo.

Differentiable digital signal processing is a technique in which signal processing algorithms are implemented as differentiable programs used in combination with deep neural networks. The advantages of this methodology include a reduction in model complexity, lower data requirements, and an inherently interpretible intermediate representation. In recent years, differentiable audio synthesizers have been applied to a variety of tasks, including voice and instrument modelling, synthesizer control, pitch estimation, source separation, and parameter estimation. Yet despite the growing popularity of such methods, the implementation of differentiable audio synthesizers remains poorly documented, and the simple formulation of many synthesizers belies their complex optimization behaviour. To address this gap, this tutorial offers an introduction to the fundamentals of differentiable synthesizer programming.

The tutorial will centre around practical demonstrations, which participants can follow using an accompanying suite of Jupyter notebooks. All tutorial content will be documented in an accompanying web book, and all tutorial materials and dependencies will be fully open source and accessible for free online. Prior experience with writing Python 3 code is assumed, and a basic knowledge of PyTorch is beneficial though not strictly required. The tutorial is targeted at music and audio researchers and engineers with a grounding in the basics of digital signal processing and machine learning. Our aim is to equip participants to apply these techniques in their own research, whilst enabling those with prior knowledge to sharpen their skills.

With the rise of the attention mechanism and the success of auto-regressive generative modelling and large language models, the Transformer architecture has arguably been the most promising technology for symbolic music generation. While audio-based methods have shown promise, symbolic music generation offers distinct advantages in terms of control, long-term coherence and computational efficiency. This tutorial explores the potential of the Transformer architecture in symbolic music generation and aims to provide (1) a thorough understanding of the vanilla Transformer architecture (emphasising the reasoning behind its design choices) and the utilisation of large language models for symbolic music generation. Additionally, it offers (2) a comprehensive overview of the field, including a taxonomy and a curated list of valuable datasets. The tutorial delves into (3) an in-depth analysis of Transformer variants and large language models specifically tailored for symbolic music generation. Also, it examines (4) examples and advanced considerations such as style, musical conditioning, and real-time performance. Furthermore, the tutorial offers (5) two hands-on exercises using Google Colab Notebooks, enabling participants to apply the concepts covered. Overall, this tutorial equips participants with the theoretical knowledge and practical skills necessary to explore the power of the Transformer architecture in symbolic music generation.

Computer-Assisted Music-Making (CAMM) systems, are software-based tools designed to assist and augment the musical creativity of composers, performers, and music enthusiasts. CAMM systems encompass a wide range of systems that can be broadly categorized into two main types according to their design purposes: to assist music performance and to assist music composition. This tutorial offers a comprehensive review of the design principles, practical applications, taxonomy, and the state-of-the-art research of CAMM systems, with an emphasis on systems assisting music performance, which are also called “interactive music systems” or “musical agents” in the literature. Research on CAMMs is interdisciplinary in its nature, combining fields such as Music Information Retrieval (MIR), Artificial Intelligence (AI) and Human-Computer Interaction (HCI). Participants will gain an understanding of how these fields converge to create innovative and interactive musical experiences. This tutorial will also feature a coding session for participants to build a real-time musical agent, under the framework of Euterpe, a prototyping framework for creating music interactions on the Web. The tutorial will examine existing systems built using Euterpe, provide insights into the development process, and guide participants through the creation of their own musical agents.

5 Learning with Music Signals: Technology Meets Education


Meinard Müller, International Audio Laboratories Erlangen, Erlangen, Germany


Music information retrieval (MIR) is an exciting and challenging research area that aims to develop techniques and tools for organizing, analyzing, retrieving, and presenting music-related data. Being at the intersection of engineering and humanities, MIR relates to different research disciplines, including signal processing, machine learning, information retrieval, musicology, and the digital humanities. In this tutorial, using music as a tangible and concrete application domain, we approach the concept of learning from different angles, addressing technological and educational aspects. In this way, the tutorial serves several purposes: we give a gentle introduction to MIR, highlight avenues for developing explainable machine-learning models, discuss how recent technology can be applied and communicated in interdisciplinary research and education, and introduce a new software package for teaching and learning music processing.

Our primary goal is to give an exciting tutorial that builds a bridge from basic to advanced techniques in MIR while highlighting technological and educational aspects. This tutorial should appeal to a broad audience, including students, educators, non-experts, and researchers new to the field, by covering concrete MIR tasks while providing many illustrative audio examples.

We present a tutorial on MIR with the open-source Kymatio (Andreux et al., 2020) toolkit for analysis and synthesis of music signals and timbre with differentiable computing. Kymatio is a Python package for applications at the intersection of deep learning and wavelet scattering. Its latest release (v0.4) provides an implementation of the joint time—frequency scattering transform (JTFS), which is an idealisation of a neurophysiological model that is commonly known in musical timbre perception research: the spectrotemporal receptive field (STRF) (Patil et al., 2012). In the MIR research, scattering transforms have demonstrated effectiveness in musical instrument classification (Vahidi et al., 2022), neural audio synthesis (Andreux et al., 2018), playing technique recognition and similarity (Lostanlen et al., 2021), acoustic modelling (Lostanlen et al., 2020), synthesizer parameter estimation and objective audio similarity (Vahidi et al., 2023, Lostanlen et al., 2023).

The Kymatio ecosystem will be introduced with examples in MIR:

Wavelet transform and scattering introduction (including constant-Q transform, scattering transforms, joint time–frequency scattering transforms, and visualizations) MIR with scattering: music classification and segmentation A perceptual distance objective for gradient descent Generative evaluation of audio representations (GEAR) (Lostanlen et al., 2023)

A comprehensive overview of Kymatio’s frontend user interface will be given, with examples of extensibility of the core routines and filterbank construction.

We ask our participants to have some prior knowledge in:

Python and NumPy programming (familiarity with Pytorch is a bonus, but not essential) Spectrogram visualization Computer-generated sounds

No prior knowledge of wavelet or scattering transforms is expected.
