The connection between improvisation in jazz and Indian classical music is found in the genre called fusion
Explanation:
Fusion is a genre in which there is a blend of Indian classical music with jazz.
This culmination of two great musical traditions comes from the backdrop of both the genres being essentially abut improvisation over a set of rules that may or may not be broken as frequently.
Both Indian classical music and Jazz have a very strong basis in musical theory which is incredibly complex, but the maestros of both the art forms often break away from the theory and improvise on the set musical pieces to interpret them in their own ways.
