  • Credit value: 20 credits

Module summary

This module considers the production, perception and acoustic features of different musical sounds and how they can be analysed within a musical framework. You will learn about different approaches to Music Information Retrieval (MIR), how to design and implement your own MIR systems, the real-world applications of MIR, and how MIR is used in different fields of research as a tool to understand music-making and listening from different perspectives . The voice, which is inherently unique as an acoustic system, will be considered in depth within the context of current MIR frameworks and how they might be limited by musical style, instrumental characteristics, instrument combinations, and other environmental factors such as room acoustics.

Module aims

Subject content aims:

  • To illustrate through demonstrations and practical sessions current Music Information Retrieval (MIR) techniques

  • To provide an appropriate level of understanding of voice acoustics to approach MIR for the singing voice, including phonetics and phonetic descriptors to enable students to describe and identify vocal sounds.

  • To explore current methods of MIR, including using MatLab to implement existing MIR toolboxes, identifying limitations and potential improvements to the systems being implemented

  • To consider the role of MIR in the context of the ways in which people engage with music and technology, and its applications across other fields such as psychology, linguistics, and digital media.

Graduate skills aims:

  • To develop skills in critically evaluating and synthesising new information based on researched information and writing concise technical reports appropriate for the target audience

  • To develop advanced skills in designing, delivering and defending engaging presentations on advanced topics, appropriate for the target audience

Presentation: A 3-5 minute video demonstrating the MIR tool that the student has created or implemented.

Labs: The students will write up and submit the assessed portion of the short exercises they will work on during the practicals.


MIR Implementation with report: The students will write a report in the style of a journal article on an MIR implementation they have conducted. They may choose to write their own MIR tool or systematically assess the limitations of existing software. They will submit accompanying sound files as appropriate.

Module feedback

Formative assessment:

The module is designed with a lot of contact time that involves short interactive practical tasks in workshops and practicals that allow you to get informal verbal feedback from the instructors to support your learning on the module. You will also work with your classmates in group exercises and receive peer feedback this way. You can also email any questions to the module leader, who will reply as soon as possible.

Summative assessments:

For each summative assessment you will receive an individual feedback sheet. The marks and feedback will be broken down as in the mark scheme to show where marks have been awarded. As well as matching descriptions from the mark scheme you will receive additional comments about your work, to support your development on the course and your skills beyond the masters.
