Chords to Progressions
A few days ago I recorded a video for YouTube-Grassapelli. It continues the discussion of chords.
Now that I’ve covered inversions, major and minor chords, it’s time to move on to chord progressions.
This is a Western Culture invention. Now the whole world uses chord progressions in their music. But, even a few decades ago this was not so. Chords conquer. It’s a benign imperialism.
A chord progression takes the tone center from the home key, the home chord, and moves it into another chord. Soon the tone center is back where it started. That completes the progression.
There is some mystery to how this works. You can take a melody and use different chords to achieve different effects. There can be disagreement about what chords should be used. I’ve read that the question of using an A minor chord versus an F chord in the B part of Billy in the Low Ground can degenerate to a fist fight in Texas.
A progression can be as simple as going to the five chord and back to the one chord. Jambalaya and Take Me Back to Texas are two examples.
The strongest movement in chord progressions is down a fifth, (or up a fourth). The first one is typical of a cadence, the two closing chords of a piece. The second is typical of many tunes and songs. Bill Cheathum, You Are My Sunshine, and Will the Circle Be Unbroken, all use this one to four movement.
Combining the plan of going to the four and back to the one, then to the five and back to the one gives the chord structure of a good many songs. Twelve bar blues is the perfect paradigm of this plan.
The blues chord progression has been my goal from the start of the chords for fiddling project. During the time I’ve been doing it, some other ideas have occurred that should yield an extra video or two.
