Abstract:
1. Method for recognizing similarly recurring patterns of notes in a piece of music, which contains note sequences distributed on parallel channels comprising the steps of: a) repeatedly segmenting each channel by varying segment length and segment beginning and, for each type of segmentation, determining segments that are similar to one another and storing these in lists of candidate patterns with their respective instances, i.e. one list respectively for each type of segmentation and channel; b) calculating an intrinsic similarity value for each list, which is based on the similarities of the instances of each candidate pattern of a list with one another; c) calculating coincidence values for each list for each channel with respect to the lists for all other channels, which is respectively based on the overlaps of instances of a candidate pattern of one list with instances of a candidate pattern of the other list when these overlap at least twice; and d) combining the intrinsic similarity and coincidence values for each list to form a total value for each list and using the pattern candidates in the lists with the highest total value in each channel as recognized note patterns in the channel.
