Pentatonic Harmonics in Fourier Transforms: Why the Blues are Blue

Why do the Blues make one blue? It is commonly known and accepted throughout the world that upon hearing a Blues song, one will feel a certain sadness and the melancholy experienced by the composer. We choose the blues musical scale to illustrate and propose a new methodology of understanding why certain parameterized waveforms upon entering a human’s ear’s cause that human to experience an emotion of sadness. Furthermore, the aforementioned methodology’s data output is conducive to KDD applications in that it includes feature extraction and decision model construction. The discussion of analyzing waveform combinations as set forth in this paper will provide progress in the optimization of emotions in sound representation. We believe that further research in this area would provide background for mining automatic multimedia content description in terms of emotion.
