In this paper, we follow up on the recently emerged idea of “computational strangeness,” which represents algorithmic recommendations as artistic obstructions in creative work. The concept of “strangeness” stems from a process of user engagement in the context of a collaboration between Hu- man Computer Interaction (HCI) and Music Information Retrieval (MIR), in which professional makers of Electronic DanceMusic requested tools that abandon the“more-of-the- same” paradigm of similarity-based retrieval in favor of the possibility to get serendipitous, opposing results to stim- ulate the creative process. We describe a prototype that allows the user to explore the space of dissimilarity for the case of rhythmic patterns by means of a simple dial. This “strangeness dial” allows the gradual adjustment of the de- gree of desired otherness. We test this initial prototype in a questionnaire-based user study to inform future develop- ments. A central outcome is that dissimilarity-based no- tions, such as “otherness” and “strangeness”, — even more than similarity — are highly subjective concepts that can not be addressed without strategies for personalization.
