Abstract:
1. An apparatus for determining a relation between a test piece of music and a reference piece of music, comprising: an input interface for providing an encoded rhythmic pattern of the test piece of music, the encoded rhythmic pattern having velocity values associated with grid positions at a first rhythmic level in a first group and having velocity values associated with grid positions at a second rhythmic level in a second group, wherein the first group and the second group are in sequence to each other; a database having an encoded rhythmic pattern for at least one reference piece of music; a search engine for comparing the encoded rhythmic pattern of the test piece of music to the encoded rhythmic pattern of the reference piece of music, the search engine being operative to correlate the first group of velocity values of the encoded test rhythmic pattern to a first group of velocity values of the encoded rhythmic pattern for the reference piece of music, before comparing further velocity values; and an output interface for indicating the relation between the test piece of music and the reference piece of music based on the correlation result.
