Motivation is a key word in the arts and, especially, in music since it conveys collective, as well as individual, feelings. The beginning of musical instrument learning should be based on the student's musical interest but, due to the casual and improvised nature of everyday situations in which the choice of a musical instrument takes place, tend to underestimate the attention that such interest deserves. This research paper seeks to expound on the lack of knowledge by students as regards musical instruments and on the powerful influence over them by instrumentalists in their environment.
