Towards Complexity Studies of Indonesian Songs

We see some complex properties from Indonesian music discography by means of music as perceived by Indonesian people. This covers the folk songs, national anthems, popular songs by Indonesian modern artists and performers and also from western popular and classical music as reference. The self-similarity is drawn by using the model of gyration and the internal dynamics of the pitches and durations used in songs is observed by using the logarithmic spiral model. The employed entropy model is also discussed as well as introduction to the calculated dynamic complexity of melodic structure. Some generalization on the flow of music respect to the dynamic complexity is also shown. We discover that at least there are two phases in the played song: the shorter introductory phase that ends in the peak of complexity of the song and the attenuating phase of complexity in which the multiple equilibria of the song is measured. The paper draws some interesting aspects regarding to those parameters and variables on Indonesian melodic corpora.
