Identifying copies or dierent versions of a same musical
work is a focal problem in maintaining large music databases. In this
paper we introduce novel ideas and methods that are applicable to metered,
symbolically encoded polyphonic music.We show how to represent
and compare polyphonic music using a tree structure. Moreover, we put
for trial various comparison methods and observe whether better comparison
results can be obtained by combining distinct similarity measures.
Our experiments show that the proposed representation is adequate for
the task with good quality results and processing times, and when combined
with other methods it becomes more robust against various types
