This paper discusses the issue of users' retrieval strategies in relation to development of a kansei-based music retrieval system. Little attention has been paid to this issue in this research area, even though it is important to build such systems. To study this issue, we performed two experiments regarding users' strategies for retrieving desired tunes using kansei-based music retrieval interface. Twenty-three subjects expressed their selections using two input methods in random order. One is uses all 19 pairs of kansei words. We call it a "passive selection". The other method allows selection of preferred kansei settings from among the 19 pairs. We call it an "active selection". It was found from the results that users' retrieval strategies were influenced by selection methods. Moreover, the results indicate the rating of midrange inputs is not very important factor for users in the music information retrieval.
