Intonation Analysis of Rāgas in Carnatic Music

Intonation is a fundamental music concept that has a special relevance in Indian art music. It is characteristic of a rga and key to the musical expression of the artist. Describing intonation is of importance to several music information retrieval tasks such as developing similarity measures based on rgas and artists. In this paper, we first assess rga intonation qualitatively by analysing varN{dot below}aṁs, a particular form of Carnatic music compositions. We then approach the task of automatically obtaining a compact representation of the intonation of a recording from its pitch track. We propose two approaches based on the parametrization of pitch-value distributions: performance pitch histograms, and context-based svara distributions obtained by categorizing pitch contours based on the melodic context. We evaluate both approaches on a large Carnatic music collection and discuss their merits and limitations. We finally go through different kinds of contextual information that can be obtained to further improve the two approaches. © 2014 Taylor & Francis.This research was partly funded by the European Research Council under the European Union's Seventh Framework Program, as part of the CompMusic project (ERC grant agreement 267583).

Acoustic Feature Identification to Recognize Rag Present in Borgit

In the world of Indian classical music, raga recognition is a crucial undertaking. Due to its particular sound qualities, the traditional wind instrument known as the borgit presents special difficulties for automatic raga recognition. In this research, we investigate the use of auditory feature identification methods to create a reliable raga recognition system for Borgit performances. Each of the Borgits, the devotional song of Assam is enriched with rag and each rag has unique melodious tune. This paper has carried out few experiments on the audio samples of rags and a few Borgits sung with those rugs. In this manuscript three mostly used rags and a few Borgits  with these rags are considered for the experiment. Acoustic features considred here are FFT (Fast Fourier Transform), ZCR (Zero Crossing Rates), Mean and Standard deviation of pitch contour and RMS(Root Mean Square). After evaluation and analysis it is seen that FFT  and ZCR are two noteworthy acoustic features that helps to identify the rag present in Borgits. At last K-means clustering was applied on the FFT and ZCR values of the Borgits and were able to find correct grouping according to rags present there. This research validates FFT and ZCR as most precise acoustic parameters for rag identification in Borgit. Here researchers had observed roles of Standard deviation of pitch contour and RMS values of the audio samples in rag identification. &nbsp

Open Access Musicology

"In the fall of 2015, a collection of faculty at liberal arts colleges began a conversation about the challenges we faced as instructors: Why were there so few course materials accessible to undergraduates and lay readers that reflected current scholarly debate? How can we convey the relevance of studying music history to current and future generations of students? And how might we represent and reflect the myriad, often conflicting perspectives, positions, and identities that make up both music’s history and the writers of history? Here we offer one response to those questions. Open Access Musicology is a collection of essays, written in an accessible style and with a focus on modes of inquiry rather than content coverage. Our authors draw from their experience as scholars but also as teachers. They have been asked to describe why they became musicologists in the first place and how their individual paths led to the topics they explore and the questions they pose. Like most scholarly literature, the essays have all been reviewed by experts in the field. Unlike all scholarly literature, the essays have also been reviewed by students at a variety of institutions for clarity and relevance. These essays are intended for undergraduates, graduate students, and interested readers without any particular expertise. They can be incorporated into courses on a range of topics as standalone readings or used to supplement textbooks. The topics introduce and explore a variety of subjects, practices, and methods but, above all, seek to stimulate classroom discussion on music history’s relevance to performers, listeners, and citizens.
