Objectives and Key Themes

This book aims to identify key features of musical signals that allow for the objective classification of Hindustani ragas. The research explores methods for classifying ragas based on various parameters and statistical modeling techniques. The study contributes to the scientific understanding of Indian classical music, specifically Hindustani music, through quantitative analysis.

• Objective classification of Hindustani ragas using signal processing techniques.
• Analysis of artist-specific variations in raga performance.
• Statistical comparison of "restful" and "restless" ragas.
• Statistical modeling of raga performance using exponential smoothing methods.
• Exploration of the relationship between musical features and perceived emotion.

Chapter Summaries

Introduction: This chapter provides background information on the study of Hindustani ragas and the challenges associated with their objective classification. It highlights the unique characteristics of Indian music, specifically its melodic structure (ragas), and discusses the need for objective classification methods in the context of large digital music libraries. The chapter defines the book's objective – to find important features of the music signal for raga classification – and outlines the book's structure.

Study of Artist Behaviour from Raga Performance: This chapter investigates the use of Mel Frequency Cepstral Coefficients (MFCCs) and statistical parametrization to analyze the performance of Hindustani ragas by different artists. The analysis aims to determine whether artists belonging to the same Gharana (musical school) exhibit similar performance characteristics. The results are analyzed using Andrew plots to visualize similarities and differences in raga interpretations. This chapter establishes a methodology for using quantitative analysis to study subtle variations in raga performances.

Comparison Between Restful and Restless Ragas Using Basic Statistical Features: This chapter compares "restful" and "restless" ragas using basic statistical features and inter-onset intervals. The research methodology is explained, and experimental results are presented. The focus is on identifying statistically significant differences in pitch transitions and frequency movements between the notes of these two types of ragas. The study demonstrates that quantitative analysis can reveal distinctions in the perceived emotional impact of different ragas.

Comparison Between Restful and Restless Ragas Using Advanced Statistical Features: This chapter extends the previous chapter’s analysis by employing advanced statistical features to compare restful and restless ragas. The methodology involves statistical modeling of raga performances, specifically using single and double exponential smoothing techniques for different ragas (Pilu, Todi, and Bhairavi). The chapter discusses the results and their implications for understanding the differences between these two types of ragas, highlighting the efficacy of different statistical models for representing various musical characteristics.

Statistical Modeling of Raga Todi Performance: This chapter focuses on the statistical modeling of the raga Todi, a raga considered restful in nature. The chapter provides background on Indian Classical Music and the musical features of raga Todi. It uses double exponential smoothing to model the raga's performance, presenting the model equation, forecasts, and experimental results. The discussion section analyzes the model's accuracy and its insights into the temporal structure of the raga. The chapter demonstrates the application of time-series analysis techniques to understanding the characteristic patterns of a specific raga.

Statistical Study of Music Emotion: This chapter explores the relationship between statistical parameters extracted from musical signals and the perceived emotion in Hindustani music. It details the research methodology employed, including the statistical parameterization used, and presents the experimental results. The chapter aims to provide quantitative evidence linking specific musical features to the listener's perception of emotional content within the music, suggesting a potential path towards automatically classifying music based on its emotional impact.
