Hello! Thought I'd update anyone that's interested: we have the results! As expected, after playing there was an increase in positive emotions and a decrease in negative emotions. Nothing shocking there, but there is a more interesting finding: that for positive emotions, there was an increase in activated affect (this is playing for enjoyment and excitement) and safe-content affect (playing to feel safer and more secure in yourself) but there was no significant effect on playing to feel relaxed/less stressed. This is one of the first studies on the effects of playing a musical instrument and there are still many unanswered questions we could not address with one study, but this gives a baseline that future research could work from, as well as giving a scientific measure to the relationship. If anyone has any further questions feel free to ask
