Seven Swaras Endless Numbers: Discovering the Maths Hidden in Carnatic Music

Did you know a raga's name secretly tells you its serial number? Or that the 72 melakartas exist because of one line of arithmetic: 2 × 6 × 6?

For centuries, Carnatic music has been taught as an art — and mathematics as a school subject that lives in a different notebook. This book puts the two notebooks side by side and shows young readers they were always describing the same universe.

Written for ages 10–15, Seven Swaras, Endless Numbers takes the music a child can already hum — Sa Ri Ga Ma — and uses it to unlock real mathematics:

Factorials — how 7 swaras explode into 5,040 melodies Permutations — arohana, avarohana and the vakra ragas as arrangements Combinations — the airtight counting argument behind the 72 melakartas The katapayadi code — the ancient number cipher hidden in raga names Algebra — the varisais you practise daily, revealed as rules and sequences Fractions & remainders — talas, the three speeds, and rhythm that wraps around Ratios — why Sa and Pa sound perfect together (it's 3:2) Trigonometry & waves — the sine curve inside every note, and the gamaka as a graph Every concept is explained through swaras, ragas and talas — never in isolation — with 20 original full-colour illustrations, Maths Spotlight definitions, Did You Know? surprises, Try It Yourself activities, and answers at the back. No prior training in music or maths is needed; a willingness to hum and to count is enough.

From the author of Carnatic Music, Decoded , founder of Lakshya's Violin Academy, Chennai — a teacher, parent and engineer who took twenty-five years to discover the science inside the art, and wrote this book so today's children won't have to wait that long.

Music is the poetry. Mathematics is the grammar. This book teaches you to read both at once .
