The issue of tuning in Indian classical music has been, historically, a matter of theoretical debate. In this paper, we study its contemporary practice in sung performances of Carnatic and Hindustani music following an empiric and quantitative approach. To do so, we select stable fundamental frequencies, estimated via a standard algorithm, and construct(More)
In order to model a culture-specific content-based music recommendatio/n system, a total of 750 subjective emotional responses to tunes composed in popular <i>raagas</i> of South Indian classical (Carnatic) music are empirically investigated to find out the long speculated relation between <i>raagas</i> (indian music scales) and <i>rasas</i> (emotion(More)
Intonation is an important concept in Carnatic music that is characteristic of a raaga, and intrinsic to the musical expression of a performer. In this paper we approach the description of intonation from a computational perspective, obtaining a compact representation of the pitch track of a recording. First, we extract pitch contours from automatically(More)
Raaga is the spine of Indian classical music. It is the single most crucial element of the melodic framework on which the music of the subcontinent thrives. Naturally, automatic raaga recognition is an important step in computational musicology as far as Indian music is considered. It has several applications like indexing Indian music, automatic note(More)
By mining user-generated text content we can obtain musicrelated information that could not otherwise be extracted from audio signals or symbolic score representations. In this paper we propose a methodology for extracting music-related semantic information from an online discussion forum,, dedicated to the Carnatic music tradition. We first(More)
In the context of the CompMusic project we are developing methods to automatically describe/annotate audio music recordings pertaining to various music cultures. As a way to demonstrate the usefulness of the methods we are also developing a system to browse and interact with specific audio collections. The system is an online web application that interfaces(More)
User recall patterns related to multi-attribute data match paradigms more suited to facet browsing than keyword-based search. Canonical keyword-based search methodologies put an undue cognitive load on the user in requiring that the user phrase his/her thoughts into keywords to be used as input for such approaches. Facet classification has been an active(More)
Intonation is a fffndamental mffsic concept that has a special relefiance in Indian art mffsic. It is characteristic of the rāga and intrinsic to the mffsical expression of the performer. Describing intonation is of importance to sefieral information retriefial tasks like the defielopment of rāga and artist similarity measffres. In offr prefiioffs flork,(More)
The classical music traditions of the Indian subcontinent, Hindustani and Carnatic, offer an excellent ground on which to test the limitations of current music information research approaches. At the same time, studies based on these music traditions can shed light on how to solve new and complex music modeling problems. Both traditions have very distinct(More)
