There are many ways to get inspiration for chord progressions. One way is to find one of your favorite songs and learn the chords of the songs. Once you get a few songs figured out you may begin to notice certain patterns emerge. Of course there are other ways to find and discover chord progressions.
Here is a basic “Formula” for creating chord progressions.
- Each key comprises of three different classes of chords. These classes are called, Tonic, Dominant, and Sub-Dominant.
- The tonic class consists of two chords, one built upon the first scale step. The tonic note is the first note of the major scale, The two chords of the tonic class include the I and vi chords.
- The dominant class consists of notes based on the fifth scale step. The dominate also has three chords. These chords include the V, iii and vii chords. The vii is seldom used.
- The last class of chords is the sub-dominant. This class contains two chords. These chords include the IV and ii chords. The basis of this class is built on the second note of the scale.
Basic rules for movement.
- The chords in the Tonic class may progress or move to any other chord in the the same key
- The chords of the Dominant class can primarily progress into those of the Tonic class. On occasion, it the dominant move to the sub-dominant but preference is given to the tonic.
- The chords of the sub-dominant class mostly progress to the dominant class.
