It’s known that music has the potential to
change emotional states and can distract listeners from negative thoughts and
pain. It has also been proven to help improve memory, performance, and mood.
Researchers at Hong Kong University of Science and Technology have recently
developed an app that creates custom playlists to help listeners care for their
emotions through music.
“As humanity’s universal language, music
can significantly impact a person’s physical and emotional state,” said
Law. “For example, music can help people to manage pain. We developed this
app as an accessible first aid strategy for balancing emotions.”
The app could be used by people who may not
want to receive counseling or treatment because of feelings of shame,
inadequacy, or distrust. By taking listeners on an emotional roller-coaster
ride, the app aims to leave them in a more positive and focused state than
where they began.
Users take three self-led questionnaires in
the app to measure their emotional status and provide the information needed to
create a playlist. Current emotion and long-term emotion status are gauged with
a pictorial assessment tool that helps identify emotions in terms of energy
level and mood. Energy level can run from high, medium, to low and mood can
register as positive, neutral, or negative. A Patient Health Questionnaire and
a General Anxiety Disorder screening are also used to establish personalized
music therapy treatments.
By determining the emotional state of the user,
the app creates a customized and specifically sequenced playlist of songs using
one of three strategies: consoling, relaxing, or uplifting. Consoling music
reflects the energy and mood of the user, while relaxing music provides a
positive, low energy. Uplifting music is also positive but more high energy.
“In our experiments, we found out that
relaxing and uplifting methods can significantly move listeners from negative
to more positive emotional states. Especially, when listeners are at a neutral
mood, all three proposed methods can change listeners’ emotions to more
positive,” said Law.
