The Emotional Effect of Semi Classical Carnatic Music using Linguistic Aggregated Fuzzy Relational Maps

Abstract

primary motivation for listening to music is its emotional effect. Assigning musical emotion to a song segment in a deterministic way does not work well because not all people share the same feeling for a song. The success of becoming a hit song from the same raga song among people is its musical features within the song. The subjective nature of listening knowledge of human to different Carnatic raga perception suggests that fuzzy logic is a more appropriate tool for an unsupervised data. This paper deals with the Linguistic Aggregated Fuzzy Relational Maps which is the combination of the linguistic variables with their aggregation and Fuzzy Relational Maps. LAFRMs method is mostly used for humans' expression or feelings expressed for the causes and its effects in terms of linguistic languages. The process of expressing linguistic knowledge is described as unsupervised data. The problem of musical emotions caused by thirteen Carnatic ragas based Tamil songs were analyzed using LAFRMs. This is the first attempt of using fuzzy tool to analyze this problem. The result shows the effectiveness of the proposed method for the application in this linguistic environment. Keywordsvariables, Triangular fuzzy number, Fuzzy relational maps, Carnatic raga, Musical feature. individual or a group is observed. Further linguistic variables are aggregated with the use of triangular fuzzy numbers. Then the model has been developed to apply in an uncertain linguistic environment. Few ideas about Carnatic ragas and Musical Features are explained in this section. Rest of this paper consists of three sections. In section 2, the preliminary definitions on the proposed method are given. The problem description and adaptation of the method discussed in section 3. Conclusions are derived in the final section to show the effectiveness of the proposed method. 1.1 Carnatic Ragas One of the melodic modes used in Indian Classical music is a raga. They use a series of five or more musical notes in which a melody is constructed. These ragas are associated with seasons and emotions in the Indian musical tradition. Indian film and devotional song composers often use non-classical form ragas in their compositions. There are 72 Melakarta ragas and derived sub ragas in the system. Improvisation plays a major role in Carnatic music. Some musical feature ideas used in composition are explained below.
