| Abstract | The tonic is a fundamental concept in Indian classical music
since it constitutes the base pitch from which a lead
performer constructs the melodies, and accompanying instruments
use it for tuning. This makes tonic identification
an essential first step for most automatic analyses of Indian
classical music, such as intonation and melodic analysis,
and raga recognition. In this paper we address the task
of automatic tonic identification. Unlike approaches that
identify the tonic from a single predominant pitch track,
here we propose a method based on a multipitch analysis of
the audio. We use a multipitch representation to construct
a pitch histogram of the audio excerpt, out of which the
tonic is identified. Rather than manually define a template,
we employ a classification approach to automatically learn
a set of rules for selecting the tonic. The proposed method
returns not only the pitch class of the tonic but also the precise
octave in which it is played. We evaluate the approach
on a large collection of Carnatic and Hindustani music, obtaining
an identification accuracy of 93%. We also discuss
the types of errors made by our proposed method, as well
as the challenges in generating ground truth annotations.
