Abstract
Methods for music structure analysis of a piece of music includes determining predetermined features for a plurality of sections of the piece of music. The sections are longer than a shortest time span corresponding to a meaningful part of the piece of music. At least two sections are compared based on the predetermined features, and a chorus of the piece of music is determined based on a comparison result of the comparing. First and second groups of the sections are determined, such that a similarity among sections of the first and second groups lie within respective first and second ranges. The first range has a higher level than the second range.
Claims21
A method for music structure analysis of a piece of music, comprising:
- determining predetermined features for a plurality of sections of said piece of music, wherein said sections are longer than a shortest time span corresponding to a meaningful part of said piece of music;
- comparing, by a processor, at least two sections based on said predetermined features;
- determining a chorus of said piece of music based on a comparison result of said step of comparing;
- and
- determining first and second groups of said sections, wherein
- a similarity among sections of said first group lies within a first range and a similarity among sections of said second group lies within a second range, said first range having a higher level than said second range.
A device for music structure analysis of a piece of music, comprising:
- means for determining predetermined features for a plurality of sections of said piece of music, wherein said sections are longer than one second;
- means for comparing at least two sections based on said predetermined features;
- means for determining a chorus of said piece of music based on a comparison result of said step of comparing;
- and
- means for determining first and second groups of said sections, wherein
- a similarity among sections of said first group lies within a first range and a similarity among sections of said second group lies within a second range, said first range having a higher level than said second range.
A computer readable medium storing computer program instructions that cause a computer to execute a method of music structure analysis of a piece of music, said method comprising:
- determining predetermined features for a plurality of sections of said piece of music, wherein said sections are longer than one second;
- comparing at least two sections based on said predetermined features;
- determining a chorus of said piece of music based on a comparison result of said step of comparing;
- and
- determining first and second groups of said sections, wherein
- a similarity among sections of said first group lies within a first range and a similarity among sections of said second group lies within a second range, said first range having a higher level than said second range.
