This book addresses the acoustic signal analysis and spectral dynamics of the tanpura, an Indian plucked string instrument. In addition, it strives to provide a logical and objective explanation of Indian classical musicians’ cognitive experience. Issues of relevance in this regard include the rich, mellifluous sound; the undulation of the loudness; the somewhat cyclical variation of the timbre, which is strongly related to these undulations; and the occasional perception of virtual notes to which no strings are tuned.

The book analyses the materials used in the tanpura, the instrument’s simple structure, the intricacies of the lower bridge, and the theory of string vibration with variable string length. Cognitive experiments to provide the basis for perceptual quality assessment, as well as a methodology for ranking, are described. This is followed by acoustic analyses, both temporal and spectral, for sounds produced by male and female tanpuras, for each individual string and the combined one. An important aspect related to the naturalness of perceived sound, namely the intrinsically associated random perturbations, is also discussed. The apparent irregularities perceived in the acoustic signal produced by the tanpura reveal the importance of examining the signal from the perspective of non-linear analysis, an aspect that is also covered in the book.

Given its scope, the book will appeal to students and researchers in the fields of music acoustics, artificial intelligence, and cognitive science, as well as musicians and musicologists around the world. 

This edited book focus on highlighting the evolution of Indian agriculture over the past 75 years of independence, covering every sector, viz. crop science, horticulture, management of biotic & abiotic stress, post-harvest quality management, livestock, fisheries, mechanization, marketing and human resource development. The book has 30 chapters from most experienced researchers and academicians who are actively engaged in research work on the subject area of the book.  The book is in line with the strategy for new India @ 75’ brought out by NITI Ayog. It highlights India’s success stories in innovation, technology, enterprise and efficient management together to achieve overall growth while making available food, required nutrition and others ecological services. It also asses the India’s preparedness in terms of commitment toward sustainable development goal SDG). The book is a relevant reading material for both students and researchers and policy makers.
