Authored by Vikram Singh Sankhala, "The Indian Music Spectrum" offers a comprehensive exploration of the rich and diverse world of Indian music. The book begins by laying the groundwork with the fundamental concepts of Swara, Nada, Raga, and Tala, explaining the Guru-Shishya Parampara and historical texts. It then delves deep into the pillars of Indian classical music – the Hindustani and Carnatic traditions – detailing their history, forms, gharanas, composers, and unique characteristics, while also highlighting their differences and similarities. This foundational knowledge sets the stage for understanding the vast landscape that follows. Moving beyond the classical, the book navigates through the vibrant tapestry of Indian folk and regional music, exploring styles like Baul, Bhajan, Rabindra Sangeet, Bhangra, and Sufi music. It examines the historical influences that shaped Indian music, from Vedic times to colonial eras, and explores religious and regional variations. The narrative then transitions to contemporary trends, covering the rise of Indian fusion music, the impact of Western genres, and the evolution of popular and film music, including Bollywood. Featuring profiles of major classical maestros, folk legends, and contemporary icons, and detailing traditional instruments alongside modern ones, the book concludes by discussing music's role in society, education, and its future in the digital age, offering readers a complete journey through India's musical heartbeat.
