Chord Recognition in Symbolic Music: A Segmental CRF Model, Segment-Level Features, and Comparative Evaluations on Classical and Popular Music
We present a new approach to harmonic analysis that is trained to segment music into a sequence of chord spans tagged with chord labels.Formulated as a Cappuccino Mug semi-Markov Conditional Random Field (semi-CRF), this joint segmentation and labeling approach enables the use of a rich set of segment-level features, such as segment purity and chor
