Genre-specific Key Profiles
نویسندگان
چکیده
The most common approaches to the automatic recognition of musical key are template-based, i.e., an extracted pitch chroma vector is compared to a template key profile in order to identify the most similar key. General as well as domainspecific templates have been used in the past, but to the authors best knowledge there has been no study that evaluated genre-specific key profiles extracted from the audio signal. We investigate the pitch chroma distributions for 9 different genres, their distances, and the degree to which these genres can be identified using these distributions when utilizing different strategies for achieving key-invariance.

As a widely used feature in genre classification systems, MFCC is typically believed to encode timbral information, since it represents short-duration musical textures. In this paper, we investigate the invariance of MFCC to musical key and tempo, and show that MFCCs in fact encode both...

متن کاملNarrative versus Style: Effect of Genre Typical Events versus Genre Typical Filmic Realizations on Film Viewers' Genre Recognition
This study investigated whether film viewers recognize four basic genres (comic, drama, action and nonfiction) on the basis of genre-typical event cues or of genretypical filmic realization cues of events. Event cues are similar to the narrative content of a film sequence, while filmic realization cues are similar to stylistic surface cues of a film sequence. It was predicted that genre recogni...
متن کاملGenre Taxonomy
In this paper, we propose a genre taxonomy as a knowledge repository of communicative structures or “typified actions” enacted by organizational members. The Genre taxonomy aims at helping people to make sense of diverse types of communicative actions, and has three features to achieve this objective. First, the genre taxonomy represents the elements of both genres and genre systems, sequences ...
