Golden Ratio is one of the most interesting and beautiful branch of mathematics!! It was a team work along with my team mate Rezwana. We did this in 6th semester in our Assembly and microprocessor language course since our teacher told us giving a presentation on any interesting topic!!

8. Golden Ratio , Fibonacci And Music
Note in all of the above, (which is the basis of music), all of the
notes and intervals only use the Fibonacci Numbers 1, 2, 3, 5, 8, and
13.
When we take any two successive (one after the other)
Fibonacci Numbers, their ratio is very close to the Golden
Ratio:
a b b/a when b>a
2 3 1.5
3 5 1.666
5 8 1.6
8 13 1.625
