What is the best/easiest method to determine the main frequency of the

A piano. Play the input signal on a speaker and press the tangents
on the piano till you fin a tone which matches the signal.

I am confused by some options (FFT, wavelets)

Then read a book on the subject, contemplate what you read,
and become less confused.

and
I am just looking for a simple one which doesn't have to be too much
theory, but simply works.

Sure. And I would just love to find that pile of gold everybody
knows is where the ranbow ends.

I still would like to learn something, not
just reuse somebody's solution in part or in whole and not understand
anything,

Maybe you don't want that, but that's a brilliant
way to start, if you want to learn something.

but I wouldn't like to spend more then a day or two learning
the maths and so.

You are really something, aren't you? How much maths
can you learn in two days?

Do you have any suggestions regarding this? Even a
simple list of possibilities would be good, but if you have the actual
experiences or links to some good tutorials, that would be great.

I might have one or two suggestions, but they would require
some actual *work* on your part. reading books, working through
the mats, playing with code examples. You have already
excluded all of that from your list of acceptable activities,
so mentioning such options is a mere waiste of time.
