I gave a talk titled “Mathemusicking with children: Doing math and music without telling them apart” at the C. R. Rao Advanced Institute for Mathematics Statistics and Computer Science on 14 March 2015, as part of a workshop on Math, music and nature.
Slides of my talk (PDF)
The talk was about the summer of 2014 workshop on music and math for children that I co-conducted along with Mrs. Usha Narasimhan, at Brhaddhvani, Chennai.
There was a request from the audience for the “Melakarta pathways” picture. Here is a PDF you can print out. There are exactly 72 ways to traverse from the S at the left to the S at the right. Each path you take corresponds to a scale of the Melakarta system.
