So far, data representation has been based on visuals. The huge size of data verges on overuse of the visual capability. Thus, there is a need to reduce the almost exclusive use of visual techniques to represent data in order to increase our perception bandwidth. In this research, we aim to solve this problem by integrating the audio component. More precisely, we are interested in representing data using musical melodies. This paper presents a model for music elements based on human emotion, to express alert messages displayed by computer network monitoring.
