Searching notated polyphonic music using transportation distances
Rainer Typke, Remco C. Veltkamp, Frans Wiering · 2004
We present a method for searching databases of symbolically represented polyphonic music that exploits advantages of transportation distances such as continuity and partial matching in the pitch dimension. By segmenting queries and database documents, we also gain partial matching in the time dimension. Thus, we can find short queries in long database documents, and have a method more robust against pitch and tempo fluctuations in the queries or database documents than we would with transportation distances alone.
