Music on prescription could help treat emotional and physical pain

New research into how music conveys emotion could benefit the treatment of

depression and the management of physical pain.

Using an innovative combination of music psychology and leading-edge audio

engineering the project is looking in more detail than ever before at how music

conveys emotion.

The project, at Glasgow Caledonian University is supported by the Engineering

and Physical Sciences Research Council (EPSRC).

The research could lead to advances in the use of music to help regulate a

person's mood, and promote the development of music-based therapies to tackle

conditions like depressive illnesses. It could help alleviate symptoms for

people who are dealing with physical pain and even lead to doctors putting music

on a prescription that is tailored to suit the needs of an individual.

" The impact of a piece of music on a person goes so much further than thinking

that a fast tempo can lift a mood and a slow one can bring it down. Music

expresses emotion as a result of many factors, " says audio engineering

specialist Dr Don Knox, project leader. " These include the tone, structure and

other technical characteristics of a piece. Lyrics can have a big impact too.

But so can purely subjective factors: where or when you first heard it, whether

you associate it with happy or sad events and so on. Our project is the first

step towards taking all of these considerations – and the way they interact with

each other – on board. "

Mac, Professor of Music Psychology at Glasgow Caledonian

University, is also playing a central role in the initiative.

You can find out more about the research from the team involved on our Youtube

channel.

The team has already carried out an unprecedentedly detailed audio analysis of

pieces of music, identified as expressing a range of emotions by a panel of

volunteers.

Each volunteer listens to pieces of previously unheard contemporary popular

music* and assigns each one a position on a graph. One axis measures the type of

feeling (positivity or negativity) that the piece communicates; the other

measures the intensity or activity level of the music. The research team then

assess the audio characteristics that the pieces falling into each part of the

graph have in common.

" We look at parameters such as rhythm patterns, melodic range, musical

intervals, length of phrases, musical pitch and so on, " says Dr Knox. " For

example, music falling into a positive category might have a regular rhythm,

bright timbre and a fairly steady pitch contour over time. If tempo and loudness

increase, for instance, this would place the piece in a more 'exuberant' or

'excited' region of the graph. "

The team are now about to start their assessment of the impact of lyrics, and

then hope to focus on how individuals use and experience music at a subjective

level.

The ultimate aim is to develop a comprehensive mathematical model that explains

music's ability to communicate different emotions. This could make it possible,

within a few years, to develop computer programs which identify pieces of music

that will influence a individual's mood (e.g. to motivate them when exercising

or when revising for exams), meet their emotional needs and help them cope

better with physical pain.

" By making it possible to search for music and organise collections according to

emotional content, such programs could fundamentally change the way we interact

with music, " says Dr Knox. " Some online music stores already tag music according

to whether a piece is 'happy' or 'sad'. Our project is refining this approach

and giving it a firm scientific foundation, unlocking all kinds of possibilities

and opportunities as a result " .
