Balancing emotions through music

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.
