The purpose of this study was to determine differences between the same subjects' music preferences at the elementary and high school levels, and the relationship between these findings and the following variables: peer preferences, musical training, excerpt familiarity, grade, gender, and race.

Practical approach to the issue of music applicability is a multi-disciplinary taking into account the complexity of working environment, personality of modern managers and the sole human nature. Musical map could serve to HR experts in building innovative programs of staff training in accordance with organization' preferences and individuals uniqueness. Recent investigations of the connection between music and motivation, music and team work, music and creativity, music and learning process, are opening numerous options for practical applicability of music in working environment aimed at increasing existing competencies and developing the new ones. The need for an increase in staff performances has imposed a need to explore how musical practice can support creation and implementation of realistic organizational goals in intercultural environment. The main goal of this doctoral thesis is to examine musical preferences and applicability of music with its positive effects on different aspects of working environment, creating thus, via empirical research, a musical map of geographical region that could be employed to increase working performance and efficiency. In order to achieve the goals defined, a field research has been conducted via structured questionnaire including 6 socio-demographic variables (gender, age, educational degree, position in the organization, sector and working experience) and 6 dependant variables (working atmosphere, efficiency in accomplishing tasks at work, motivation, learning, team work and stress reduction). The research was conducted in Serbia, on a random sample of 126 managers and employees in Belgrade, Novi Sad and Novi Pazar. The main hypothesis was that applicative music positively affects creation of proper corporative ambient and improvement of employees' competences, and was tested via 13 auxiliary hypotheses. Main empirical outcome of the Ph.D. thesis research is the determination of Serbian working population Musical Map and results of influence of certain socio-demographic and professional factors on the Musical Map Method implementation. HR staff would subsequently implement the "concept of musical map method" within its own company that is expected to increase motivation, learning and creativity as shown empirically in the study conducted. Also team work and working efficiency are expected to increase and stress at work to decrease under the proper musical exposition and all of these are explicitly shown in the thesis research results. In addition, influence of the degree of education on musical preference at work place and in general are the most surprising data, as revealed by chi square test if independence. Although general statistics of total sample on participant's opinion, speaks in favour of hypotheses confirmation expressing positive effects of music on 6 dependent variables, there are some fine differences, influenced by cardinal and derived variables, as shown by one way ANOVA test (e.g. influence of gender on opinion of positive music effects on stress reduction etc.). The final result of the thesis is the creation of the Musical Map Method that contains original approach toward creation of musical map and determination of the necessary factors that could substantially influence its implementation. Method could be applied anywhere in the Globe to produce other unique music maps as per sponsor request.
