sjonathan02, I just want to make sure that you understand that I typically think about progressions in regards to "where I am going". So since I am going to the F, I think 2 5 1, but below is what the actual progression would be in the key of C.
G.. HAL
G.. LE
C.. LU
C.. UU
C.. JAH
Gm... HAL.......5
C7... LE .......1
F... LU ........4
F... JAH
Am... HAL ......6
D7... LE .......2
G... LU .........5
G... JAH
G... HAL
G.....LE
C... LU .......1
C... JAH
I am not really a scale expert But in this little song, there are alot of different scales you could us, C Major, F Major, Gmajor, C Pentatonic, etc...
On thing that helped me alot was when I realized that songs, even though it says it is in one key, it can change key throughout the song.
This song is an example of it.the Key is C, but it temporarily goes to the key of F and and the key G.
The secret to making this happen is have a large chord vocabulary (which I don't). This is important so you will have smooth voicing leading from one chord to the next.
