A Practical Music Retrieval System Based on Sliding Melodic Contour

Abstract

In this paper, we proposed a contour-based music retrieval system that can efficiently and properly retrieves music according to user’s query. To enhance the fault tolerance of user’s query, we use interval instead of note as the basic unit of music. We also present an index structure by using sliding window technology. Moreover, we analyzed the effects caused by varied length of query and segmentation. Experiments show the satisfying and exhilarating results in the proposed system. The average time for music retrieval is less than one second.
