Musical similarity

References

The notion of musical similarity is particularly complex because there are numerous dimensions of similarity. If similarity takes place between different fragments from one musical piece, a musical similarity implies a repetition of the first occurring fragment. As well, eventually, the similarity does not occur by direct repetition, but by presenting in two (or more) set of relations, some common values or patterns. Objective musical similarity can be based on musical features such as:

Pitched parameters

Pitch interval similarity
Melodic similarity^[1]
Modulation pattern similarity
Timbral similarity

Non-pitched parameters

Metrical structure similarity
Rhythmic pattern similarity^[2]
Section structure similarity

Semiotic parameters

Modality structure similarity
Extensional similarity
Intensional similarity

Nevertheless, similarity can be based also on less objective features such as musical genre, personal history, social context (e.g. music from the 1960s), and a priori knowledge.

Applications

Automatic methods of musical similarity detection based on data mining and co-occurrence analysis has been developed in order to classify music titles for electronic music distribution.^[3]
