Music for relaxation or relaxation for music?

Many people feel that music has powerful effects on their mood and emotions. The fact that lullabies exist attests to music’s capacity to soothe. Adults too use music to relax: they play music to focus before an exam or to cool down after a stressful day. If music is beneficial for relaxation, could relaxation be beneficial for music? A recent study by Oshin Vartanian (DRDC Toronto) and Peter Suedfeld (University of British Columbia) adds to the growing evidence that relaxation and music might be mutually beneficial.

The study aimed to test whether a particular form of relaxation could enhance certain aspects of jazz improvisation. Prior evidence had shown that floating in a virtually stimulus-less environment (floatation version of the restricted environmental stimulation technique-REST) enhances perceptual and motor skills as well as creativity in sports and sciences. This disconnection from external stimulation reduces stress and induces a state of relaxed alertness and concentration. Could the same technique also lead to improvements in the perceptual-motor and creative aspects involved in jazz improvisation?

To answer this question Vartanian and Suedfeld asked 8 students enrolled in a jazz improvisation course to undergo one floatation session, which lasted an hour, each week for 4 weeks. Five other students acted as control group. All the participants individually performed five minute long freely conceived improvisations a week before and a week after the floatation sessions. These performances were recorded and then rated by an expert for improvisation, creativity, expressiveness, technical ability, and overall quality.

The results revealed that the initial performances of both groups of students did not differ on any of the assessment dimensions. However, the participants that completed the four floating sessions scored higher on technical ability than the control students on the post-treatment performance. No significant differences were found between both groups on any of the other measures. This result was confirmed by an independent measure of progress throughout the course.

Hence, flotation REST can improve the technical aspects inherent to musical improvisation. Contrary to the authors’ initial expectations, however, the same technique did not lead to better creativity scores. This might have been because these sessions have only short-term benefits on creativity, which faded before assessment. Alternatively, creativity in performing arts might not be expressed in the same ways as it is in other fields.

Clearly these results warrant further studies to test the effects of flotation REST on other musical abilities, as well as on other performing arts, and to clarify the neural mechanisms responsible for these improvements.
