What are chord progressions?

The chord progressions are generally used to make up chords for a simple score. For example, in the key of C major, C, Dm, Em, F, G, Am, B-, C, as in the first half of "Thinking of You Everyday", you can use the classic 1645, i.e., C (dominant), Am (lower alto), F (dominant), G (dominant), and 1451 (fretted termination) is also a more common direction. In minor keys, for example, "Did Anyone Ever Tell You" is arranged in 1473 1475, i.e., Em (dominant), Am (subdominant), D (dominant), G (alto), Em (dominant), Am (subdominant), D (dominant), Bm (dominant). The chord progression has a natural chord articulation that sounds smooth and also plays the melody of the short form just right.
