GoalAn overview of the Music Information Retrieval research field while focusing on opportunities for digital musicology.
DefinitionMusic Information Retrieval is the interdisciplinary science of extracting and processing information from music.
DefinitionSignals are representations of analog manifestations and replicate perception. Symbols are discretized, limited and replicate content.

Models aim to reduce dimensions, complexity and improve understanding and readability.
Quote"Essentially, all models are wrong, but some are useful"

MIR TasksMost tasks enable to browse, categorize, query or discover music in large databases of music.
Un-mix the mixDecomposing a mixed audio signal is very very hard.
|The main soundtrack of an arcade game. It is fast-paced and upbeat, with a catchy electric guitar riff. The music is repetitive and easy to remember, but with unexpected sounds, like cymbal crashes or drum rolls.|
|A fusion of reggaeton and electronic dance music, with a spacey, otherworldly sound. Induces the experience of being lost in space, and the music would be designed to evoke a sense of wonder and awe, while being danceable.|
|A rising synth is playing an arpeggio with a lot of reverb. It is backed by pads, sub bass line and soft drums. This song is full of synth sounds creating a soothing and adventurous atmosphere. It may be playing at a festival during two songs for a buildup.|
|Slow tempo, bass-and-drums-led reggae song. Sustained electric guitar. High-pitched bongos with ringing tones. Vocals are relaxed with a laid-back feel, very expressive.|

Patterns“Patterns are fundamental in music around the world”
Why study cross-cultural patterns in music?

GoalPaPiOM: perform large-scale corpus-based studies to identify patterns in pitch use in music. Link corpus-based findings with other findings.
What if we have an easy way to detect duplicate audio?
