The relation between music and emotions has been a topic of several studies in the last two decades. We tried to find strategies that would help encourage students on piano learning, especially the youngest ones. The strategy of finding relationships between musical elements and extra-musical elements can be a way to emotionally involve the students in the music. In an experiment, whose methodology was an action-research, we asked two twelve year old piano students to create stories based on two musical pieces that were being studied by them. The aim of the present article is to search relationships between elements of the musical pieces and the extra-musical elements of the stories. We could observe how certain musical structures (such as dynamics, articulation, and others) can influence the imagination and emotions of the students.
