By comparing self-reported characteristics of these experiences, this study found that compared to listening to music, looking at painting was associated with increased frequency of wonder and decreased frequencies of joyful activation and power. In addition to increased vitality, as reflected by the latter two emotions, listening to music was also more frequently associated with emotions such as tenderness, nostalgia, peacefulness, and sadness. Compared to painting-related emotions, music-related emotions were perceived as more similar to emotions in other everyday life situations. :)
With collage, you are taking pieces or objects that are already finished, and combining them. The art is in the arrangement, rather than in the creation of the pieces or objects.
