+1 I agree. From what I've read, this actually goes back to the likes of
Bach and Beethoven. They more-or-less defined Western music with
some combination of 1,4 and 5 in there somewhere. You can find it in
an extremely high percentage of our music. If you don't find the 1-4-5,
odds are that it is some non-Western music (e.g. asian, middle-eastern,
Nickelback, etc.). (OK, just kidding on the Nickelback part.

)
By the way, the frequency of the 5th is 50% higher than the 1st.
This might be some subliminal reason why the two go together.
And the 1st is actually the 5th of the 4th (but down an octave).
In other words:
5th is 150% of a 1st.
1st is 75% of a 4th (i.e. 150% / 2).
