Taya Tan... What does it mean?

Question

Yet another Pink Martini cover (I guess it's a traditional Japanese song) Does Taya Tan mean anything?

Answer 1

I have the impression that "taya-tan" represents the sound of a beating heart.

"Taya-tan, taya-tan, taya-tan
Oh! My excitement!
Taya-tan, taya-tan, taya-tan
My heart is singing
When I come close against your chest
I play a song of love"
