Abstract
Computer-based systems, devices, and methods for assigning mood labels to musical compositions are described. A mood classifier is trained based on mood-labeled musically-coherent segments of musical compositions and subsequently applied to automatically assign mood labels to musically-coherent segments of musical compositions. In both cases, the musically-coherent segments are generated using automated segmentation algorithms.
Claims20
A computer-implemented method of labeling a musical composition with at least one mood label, the method comprising:
- segmenting the musical composition into a sequence of musically-coherent segments, the sequence of musically-coherent segments including at least two musically-coherent segments;
- and
- employing a mood classifier to assign at least one respective mood label to each respective musically-coherent segment.
A mood classifier comprising;
- processor-executable instructions and/or data stored in a non-transitory processor-readable storage medium, wherein when executed by at least one processor communicatively coupled to the non-transitory processor-readable storage medium, the mood classifier assigns at least one mood label to at least a portion of a musical composition, and wherein the processor-executable instructions and/or data are based at least in part on training data comprising a library of mood-labeled musically-coherent segments.
A computer-implemented method of training a mood classifier to assign at least one mood label to a musical composition, the method comprising:
- generating mood-labeled musically-coherent segments, wherein generating mood-labeled musically-coherent segments includes, for a set of musical compositions:
- segmenting each musical composition into a sequence of musically-coherent segments;
- and
- assigning at least one mood label to each musically-coherent segment;
- and
- training the mood classifier based on the mood-labeled musically-coherent segments.
