Abstract :
A musical composition is highly patterned as it involves repetition either in the form of individual sequences of notes, chords, dynamics, rhythmic beats or tempo etc. Hence it leads to the possibility of treating music mathematically. Though mathematics has been applied to the study of music for centuries, relatively few attempts have been made to answer questions in musicology using statistical methods. The same is also true for Indian Classical music. In North Indian classical music there arises a number of questions concerning raga characteristics that can be subjected to statistical enquiry for their proper verification. Under such circumstances statistical test procedures could be employed for examining various musical propositions corresponding to a raga composition. In this paper some non-parametric techniques such as Wilcoxon Signed rank test, Binomial test and Run test of randomness have been applied for examining such propositions related to characteristics of ragas. The concept of structure function is also utilized for defining a raga and its classification.
