Please explain this in terms of music for me..

[DwnWthVwls]

I love music but have never picked up an instrument and know nothing about the technical side of things. I want to incorporate this line in a music tattoo I am in the process of putting together but I need to understand it to see if it will make sense.

In the song Hallelujah the first verse has the lines:

Well it goes like this:
The fourth, the fifth,
The minor fall and the major lift

Can this be represented through notes as part of my design? Please explain what those things are in music.

Thank you!
