MelodyShape is an open source Java library and tool to compute the melodic similarity between monophonic music pieces. It implements several algorithms that compute similarity based on the geometric shape that melodies describe in the pitch-time plane.
All these algorithms have obtained the best results in the MIREX Symbolic Melodic Similarity task in 2010, 2011, 2012, 2013 and 2014 editions, as well as the best results reported for the 2005 collection.
MelodyShape can be run both as a graphical user interface and as a command line tool:
$ java -jar melodyshape-1.2.jar
usage: melodyshape-1.2 -q <file/dir> -c <dir> -a <name> [-k <cutoff>] [-l] [-t <num>] [-v] [-vv] [-gui] [-h]
-q <file/dir> path to the query melody or melodies.
-c <dir> path to the collection of documents.
-a <name> algorithm to run:
- 2010-domain, 2010-pitchderiv, 2010-shape
- 2011-shape, 2011-pitch, 2011-time
- 2012-shapeh, 2012-shapel, 2012-shapeg, 2012-time, 2012-shapetime
- 2013-shapeh, 2013-time, 2013-shapetime
- 2014-shapeh, 2014-time, 2014-shapetime
-k <cutoff> number of documents to retrieve.
-l show results in a single line (omits similarity scores).
-t <num> run a fixed number of threads.
-v verbose, to stderr.
-vv verbose a lot, to stderr.
-gui run with graphical user interface.
-h show this help message.
