Little more on I IV V. Here is something that no one ever gets around to telling newbies. For the melody line and the chord progression (chord line) to sound good together both should contain some of the same notes at the same time in the song. For example:
Quote:
G................................................C
Heartache number one was when you left me,
D7...............................................G
I never knew that I could hurt this way.

That first G chord harmonizes the lyrics (melody notes) until we get to the word "you" and at that point we changed to the C chord. Why? Well the melody line has moved on to notes not found in the G chord.
Quote:
The melody notes in the first line of Heartaches goes like this:
B........C.....B.....A....G...D....B.......C....E. ....E
Heartache number one was when you left me

G chord has the G, B & D notes in its makeup so those notes harmonize the first five words in the lyrics, however, when we get to "you left me" we need a chord that has the C and E notes. Well C chord is made of the C, E and G notes and will do the job very nicely.
Now my point..... the G, C & D chords are the I IV V chords in the key of G.
G chord is made of the G, B & D notes.
C chord is made of the C, E & G notes.
D chord is made of the D F# & A notes.
Now those notes just happen to be every note in the G scale. So sooner or later one of those three chords will harmonize any melody line made from the G scale. Drum roll......
Thus if you are jamming that I IV V I progression is a pretty safe progression to use.
I know I built you a clock...... but, I bet no one has told you about the melody line and the chord line needing to share some of the same notes. You really do not need to know that if playing from sheet music, but, if you are jamming it comes in handy.
Good luck.
