Similarly, energetic and positive music varied according to expected seasonal patterns in the UK, increasing in summer and decreasing in winter (see figure). The first musical dimension corresponded to audio features reflecting high intensity and positive emotions, such as happiness and joy. Interestingly, not all combinations of music features were related to weather conditions. The researchers found that only music features reflecting high intensity and positive emotions were associated with weather conditions, whereas music features reflecting low intensity and negative emotions were not related to weather at all.
