• G10H 2210/036 of musical genre, i.e. analysing the style of musical pieces, usually for selection, filtering or classification
• G10H 2210/041 based on mfcc [mel -frequency spectral coefficients]
• G10H 2210/046 for differentiation between music and non-music signals, based on the identification of musical parameters, e.g. based on tempo detection
• G10H 2210/051 for extraction or detection of onsets of musical sounds or notes, i.e. note attack timings
