Plain English Summary

Background and study aims
Music therapy or sound interventions have been shown to benefit patients in terms of pain or fear relief and improvement of other patient-reported outcomes. The effect of stress on the heart, particularly the variation in heart rate, is known to indicate that more serious problems can occur later. The aim of this study is to investigate the effects of a sound intervention on heart rate.

Who can participate?
Patients who are exposed to increased stress levels due to their illness, as well as formally healthy people, can participate in the study.

What does the study involve?
The planned study project will investigate the effects of music therapy in patients and healthy individuals with an increased stress level, in particular with regard to a possible positive effect on the autonomic nervous system in terms of stress reduction. In order to take into account a possible positive effect of music intervention, a music intervention will therefore be compared to rest. Participants will have their heart rate measured before and after a 15 period of either rest or listening to music. On another day they will do the opposite (music or rest) and measurements will be taken in a similar manner.

What are the possible benefits and risks of participating?
There are no known disadvantages for the participants in the study. There are no known harmful effects of music therapy. As music therapy is a recognised, established procedure whose effectiveness has already been proven in meta-analyses, the researchers hope to achieve a positive effect from which every participant in the study will benefit directly.

Where is the study run from?
University Medical Centre Mannheim (Germany)

Scientific title

Beneficial effects of a sound intervention in the form of music therapy on stress reduction


Study hypothesis

Music therapy is a recognised medical procedure that uses music to address physical, emotional, cognitive and social disorders. The interventions used include playing instruments, vocal and instrumental improvisation, singing, composition/songwriting, music guided imagination techniques and listening to music.
Music therapy is said to have a positive effect on well-being, stress management, pain relief, emotional expression, memory, communication skills and physical rehabilitation.
There is some evidence that music therapy can be a useful supportive measure in the treatment of chronically ill patients. Results of recent systematic reviews suggest that music interventions have moderate to strong treatment effects on the parameters of anxiety, depression, fatigue, pain and quality of life in chronically ill patients. In addition, a slight improvement in vital parameters such as heart rate, blood pressure and respiratory rate has been described, which indicate a reduction in stress. This study will therefore examine the effects of music therapy in patients exposed to higher stress levels, especially with regard to a possible positive effect on the autonomic nervous system in terms of stress reduction.

Increased stress level


All participants receive both a 15-minute sound intervention and a 15-minute rest intervention on separate days as part of a cross-over design.

The order of interventions is randomly decided using sealed envelopes.

The sound intervention was performed with an instrument called "Heaven and Earth" ( This instrument consists of a semi-open resonance body with 29 strings (24 of those in C1sharp, two in C2sharp, two C3sharp, and one in G3sharp). The monochord is placed on the chest during the intervention to ensure optimal transmission of the vibrations.

The rest intervention is done in a lying position for 15 minutes after the 10-minute resting phase.

The gap between the two intervention days is a maximum of 4 weeks.

Drug names

Primary outcome measure

Cardiovascular parameters (heart rate, blood pressure, heart rate variability and pulse wave velocity) assessed non-invasively using the VascAssist 2 device at baseline and after the rest and sound interventions

Secondary outcome measures

Quality of life assessed using the health-related quality of life (HRQOL) questionnaire at baseline and after the rest and sound interventions
