A Data-driven Bayesian Approach to Automatic Rhythm Analysis of Indian Art Music

Ajay Srinivasamurthy

(Last updated: 30 Nov 2016)


Large and growing collections of a wide variety of music are now available on demand to music listeners, necessitating novel ways of automatically structuring these collections using different dimensions of music. Rhythm is one of the basic music dimensions and its automatic analysis, which aims to extract musically meaningful rhythm related information from music, is a core task in Music Information Research (MIR). The thesis aims to build data-driven signal processing and machine learning approaches for automatic analysis, description and discovery of rhythmic structures and patterns in audio music collections of Indian art music. After identifying challenges and opportunities, we present several relevant research tasks that open up the field of automatic rhythm analysis of Indian art music. Data-driven approaches require well curated data corpora for research and efforts towards creating such corpora and datasets are documented in detail. We then focus on the topics of meter analysis and percussion pattern discovery in Indian art music. The data and tools should be relevant for data-driven musicological studies and other MIR tasks that can benefit from automatic rhythm analysis.

Meter analysis

Some audio examples of meter analysis are here:

Percussion pattern discovery

Some audio examples of percussion pattern discovery are here (examples generated with the help of Swapnil Gupta):

Audio Features

The examples below are a sonification of the spectral flux using a sawtooth signal of 800Hz with an amplitude envelope of the spectral flux feature used in the thesis. An audible click is also present at the true location of the sama (downbeat). The tracks are stereo: left and right channels have the spectral flux from low and high frequency bands, respectively.
