In most existing methods of music mood classification, the moods of songs are divided according to psychologist Robert Thayer’s traditional model of mood. Breaking a song down into quantifiable musical components such as rhythm, harmony, and timbre can allow for the matching of songs to specific categories based upon expected data for each type of mood. The mood of a piece could also improve upon algorithms for identifying similar songs for online radio services like Pandora, basing the similarities on the song’s mood rather than on similar artists. Identifying the mood of a piece automatically would be extremely useful for sorting large collections of digital music such as those of iTunes or Spotify. Attempting to categorize music through engineering techniques is challenging, but can potentially help to minimize these discrepancies between listeners in the sorting process. Much of the current organization for songs is based on an artist’s overall genre, rather than on the feeling generated by a song. The classification of music can be a difficult task since the emotional reaction between listeners can be fairly different for a given song. This article will discuss the engineering methods used to create these analyzation algorithms, and look at some of their results. These methods can be useful in determining the genre of music automatically for sorting large collections of digital music such as iTunes or Spotify. The method used then is to decide upon certain base songs that very closely embody a certain mood, and to match songs to these specific categories. The emotional reaction to music is different for every person, so analyzing it will not likely yield perfect results. The article will cover the analysis of music using various DSP and music theory techniques involving rhythm, harmony, and spectral features. ![]()
