In connection with a classification system for classifying media entities that
merges perceptual classification techniques and digital signal processing classification
techniques for improved classification of media entities, a system and methods
are provided for automatically classifying and characterizing musical consonance
properties of media entities. Such a system and methods may be useful for the indexing
of a database or other storage collection of media entities, such as media entities
that are audio files, or have portions that are audio files. The methods also help
to determine media entities that have similar consonance by utilizing classification
chain techniques that test distances between media entities in terms of their properties.
For example, a neighborhood of songs may be determined within which each song has
a similar consonance.
