Memorable life events are important to form the present selfimage. Looking back on these memories provides an opportunity to ruminate meaning of life and envision future. Integrating the life-log concept and auditory graphs, we have implemented a mobile application, "LifeMusic", which helps people reflect their memories by listening to their life event sonifcation that is synchronous to these memories. Reflecting the life events through LifeMusic can relieve users of the present and have them journey to the past moments and thus, they can keep balance of emotions in the present life. In the current paper, we describe the implementation and workflow of LifeMusic and briefly discuss focus group results, improvements, and future works.
