Algomus – Algorithmic Musicology – is a research team in Digital Humanities. We focus on high-level analysis of music scores. We work on modeling, visualizing and generating music, for music theorists, musicians, music lovers, and everyone. We are located in the Hauts-de-France region. We belong to the CRIStAL computer science department of the UniversitĂ© de Lille and have strong links with the MIS computer science lab of the UniversitĂ© de Picardie Jules-Verne, in Amiens. We are also funded by the CPER MAUvE and by Sciences et Cultures du Visuel. We use the scientific computing service MĂ©socentre de Lille.

Music co-intelligence and co-creativity

Our research is in Musical Information Retrieval (MIR), more precisely in Computational Music Analysis. Collaborating with music theorists, we focus on symbolic scores of tonal music – such as in baroque, classical, romantic, jazz, pop and dance repertoires.

We model patterns, melodies, harmony (chords, chord progressions, cadences), rhythms, texture. We ultimately aim to model music structure. Over the years, the team worked on musical forms such as fugues, variations, and sonata forms.

Bach, Fugue no. 7

We combine musicological knowledge and computer science methods in text algorithmics, data mining and machine learning, Black-box methods analyzing or producing music are not our main focus. We are rather interested in designing explainable algorithmic and AI methods, trying to model what makes music and providing people with tools to help them to understand and finally enjoy music.

Open methods, open data

We publish our methods and our corpora in the Music Information Retrieval community. Most of our data is available under open-source licenses from

Dezrann, a platform to share music analysis

Music research for everyone

We collaborate with musicians, music teachers, artists, and music companies. Dezrann, our web platform to share music analysis, is used in secondary schools to help children to think and to talk about music. We contribute to science&arts projects, to popular science events… and even sometimes to song contests with a Eurovision-like song (2020) or an ambient electronica track (2021). We organize regular seminars, open to everyone, on music, technology and computer science.
