This document discusses change trajectories in Indian culture that have been catalyzed by cross-cultural encounters. It identifies 7 change trajectories: 1) Emulation, 2) Adaptation, 3) Experimentation, 4) Partial Assimilation, 5) Resistance, 6) Complete Assimilation, and 7) New Movements. Each trajectory is explained through historical examples from the interaction between British and South Indian musicians and the development of South Indian Classical Music. The document argues that understanding historical patterns of culture change can provide insights into catalyzing change today.
