Notice how the
I chord has the same
letter name as the
1st degree of the scale, the
IV chord has the same letter name as the
4th degree and the
V chord has the same letter name as the
5th degree. This is called a
I IV V chord progression. The progression ends by returning again to the I chord.
- C = 1 = I
- D = 2 = II
- E = 3 = III
- F = 4 = IV
- G = 5 = V
- A = 6 = VI
- B = 7 = VII
- C = 8 = VIII (same as I)
I IV V chord progressions are used for the 12 bar blues, plus many rock, blue-grass, folk and other popular tunes. The V chord (G) is commonly played as a dominant 7th in order to create more tension or pull back toward the I chord (C).

This would slightly alter the
chord progression given above to:

In other words, the G7 chord can be used as a substitute for the G Major chord and vice-versa.
Now, if you are new to the guitar, this chord progression might be a little hard to play in the Key of C. In that case, we can simply transpose it into another Key!
For example, the next Key in order of sharps is G. The scale degrees are:
G A B C D E F# G
So, our I IV V I chord progression for the Key of G is: G C D G
If we convert the V chord to a dominant 7th chord we have:


*Notice how each chord gets it's name from the specific degree of the scale it is derived from.
Here are the remaining I IV V7 I chord progressions for the Keys of D A and E. This completes the first five Keys (in order of sharps).



Now that you are equiped with this information, you have the tools to start playing a wide variety of songs!
Here is a simple strumming pattern you can use...

Remember- two eighth notes equal one quarter note. Since a quarter note has a value of one beat, an eighth note has a value of only 1/2 a beat. That means you will have twice as many eighth notes when counting a 4/4 rhythm. Therefore, eighth notes are counted: 1 & 2 & 3 & 4 &
Another thing that will help your understanding is to realize that the numbers are thought of as downbeats and the &s are upbeats (ignore the arrows for now).
Try this simple arrangement of the song...
Wild Thing
Feel free to download it if you'd like. You'll need
Adobe Acrobat Reader to view it. Don't worry, it's free!
The strummming pattern for Wild Thing is:

The first and second beats are DOWN strums. Then there is an eight rest on the third beat. This is followed by an UP, DOWN, UP strum to end the measure. Notice that the arrows are pointing in the direction of the first string, which is DOWN. This can be a bit confusing at first, because the arrows are pointing up on paper. But if you think in terms of your guitar strings you should be ok.
LESSON OBJECTIVE:
To become familiar with using I IV V chord progressions in various keys.
PRACTICE:
1. Play the I IV V7 I chords in each key. Start with the Key of A as it is the easiest.
2. Once you feel comfortable with the chords in the Key of A try the same chord progression in the Key of D.
3. Continue on in this way until you are able to play the I IV V7 I chord progressions in all five Keys above.
*Remember "ECONOMY OF MOTION" as you move from chord to chord. If a finger plays the same string, but not the same fret on two different chords, DON'T PICK IT UP! Instead, SLIDE your finger along the string when moving to another fret.
