Abstract
Music recognition is carried out by accepting a musical score of musical elements in a digital format, transforming the digital format into a composite musical data object that models the musical score, defining the key signatures in the composite musical data object probabilistically, computing start times to play musical elements in respective measures of the composite musical data object without regard to rhythmic values of other musical elements in the respective measures, and generating an output including the defined key signatures and computed start times.
Claims19
A method of music recognition, comprising the steps of:
- accepting a musical score of musical elements in a digital format, the musical elements comprising measures, key signatures, and first barlines and second barlines;
- transforming the digital format into a composite musical data object that models the musical score, wherein the musical elements in the composite musical data object have coordinates;
- defining the key signatures in the composite musical data object probabilistically;
- computing start times to play musical elements in respective measures of the composite musical data object without regard to rhythmic values of other musical elements in the respective measure;
- and
- generating an output comprising the defined key signatures and computed start times.
A computer software product for music recognition, including a non-transitory computer-readable storage medium in which computer program instructions are stored, which instructions, when executed by a computer, cause the computer to perform the steps of:
- accepting a musical score of musical elements in a digital format, the musical elements comprising measures, key signatures, and first barlines and second barlines;
- transforming the digital format into a composite musical data object that models the musical score, wherein the musical elements in the composite musical data object have coordinates;
- defining the key signatures in the composite musical data object probabilistically;
- computing start times to play musical elements in respective measures of the composite musical data object without regard to rhythmic values of other musical elements in the respective measure;
- and
- generating an output comprising the defined key signatures and computed start times.
