Modelling Of Music As A Communication System And Quantitative Description Of Emotions In Carnatic Music
Sai Venkatesh Balasubramanian · viXra · 2016
The hypothesis is that Music can be broken down into melody, rhythm, harmony and lyrics, Melody and harmony playing significant roles. Melody consists of notes whose emotions sum up to give total emotion of the musical piece. In this solution, Emotions of notes are quantitatively described followed by the emotions of melodies; this gives the emotion of the musical piece. The classification of emotions given by Robert Plutchik is used. Music is modelled as a communication system. Here the channel is not additive but transformative (transforms musical notes into emotions). A statistical approach is used where the time under consideration is the instant before the singing of a note. Two events are described. Event ‘x’ is the singing of a note whose chance is restricted by the melody allowing only certain notes. Probability matrix p(x) denotes probabilities of each note in the melody i.e. Composition of the melody. Event ‘y’ is the arousing of an emotion in the listener, which is probabilistic, and the probability matrix p(y) denotes the “emotion profile” of the melody.
