By Anjum Altaf In response to the interest in our series on music (see here, here, and here), The South Asian Idea (TSAI) is following up with an interview with Arpita Chatterjee (AC) presently in charge of the Academic Research Department at the prestigious ITC Sangeet Research Academy in Kolkata and thus an ideal person to guide us in our discussions. These are her personal views. TSAI: We started our series on music with the quote from Goethe: "I call architecture frozen music." Is this metaphor of "architecture" relevant for Indian classical music? If not, what would be the appropriate metaphor that could help readers visualize Indian classical music?
