Folk songs play a very significant role in Indian classical music as the root of Indian classical music is the Indian folk music itself.

Different states have different folk songs. This work deals with the statistical analysis of the folk songs of Jharkhand. Each song's analysis concerns with verifying whether the probabilities of notes in the song are fixed throughout the song or are the note probabilities varying. This tells us whether the probability distribution followed by the notes is multinomial or quasi multinomial respectively. Statistical parameterization method is used to quantify melody and rhythm. The presence of rhythm and melody is also analyzed by the Inter Onset Interval (IOI) and note duration graphs.

The book should be found useful by music researchers and students of music and musicology, ethnomusicologists and music enthusiasts.
