This study investigates usage and knowledge of musical narrative functions in contemporary multimedia. A group of young adolescents were given the task of adapting musical expression, using the non-verbal research tool REMUPP, to fit different visual scenes shown on a computer screen. This was accomplished by manipulating seven musical parameters: instrumentation, tempo, harmonic complexity, rhythmic complexity, register, articulation and reverb. They also answered a questionnaire giving information about their musical training and media habits. Numerical data from the manipulation of the musical parameters were analysed to search for tendencies within the group with regard to the musical expression in relation to the different visual scenes shown. The results showed a large degree of in-group consensus regarding narrative functions of music, indicating knowledge about musical narrative codes and conventions. Also, the results were clearly influenced by factors such as the participants' musical training, gender and habits of music listening, playing computer games and watching movies--highlighting the complexity of learning and pointing to the impact of the increasing availability of narrative media on our attitudes and knowledge.
