The most common and popular chord progression in modern music. Including (but not limited to):

G --> C --> D
E --> A --> B
C --> F --> G

(These are all the same I IV V progression, just in different keys.)

The progression itself is: root note-->Fourth of root note-->Fifth of root note. Hence, I IV V (1, 4, 5). It works particularly well because Fourths are great for transitions and Fifths are just helpful in general. It can be applied to nearly anything, but is most commonly seen in folk music.
Songs utilizing the I IV V progression include:

- Pretty much everything by Johnny Cash (A Boy Named Sue, Folsom Prison Blues, I've Been Everywhere)
- 500 Miles by The Proclaimers
- Blitzkrieg Bop by The Ramones
- Cowboy Buttsex from Family Guy
- The Lumberjack Song by Monty Python
- Hotel Yorba by The White Stripes
