Four Chord Loops

I’ve always been nuts about simple chord progressions, especially those that are hypnotic and circular in their basic nature. If I’m tuned DAD on my dulcimer, this is one of the top circular progressions that I know of:

With an ascending bass line:

DABmG
0123
0011
2100

With a descending bass:

DABmG
76+53
5451
4400

With chords in root position:

DABmG
0453
5451
4400

Here is another chord loop, though this one has only three chords, because you come back to the second chord one more time:

ADGD
1232
0010
1000

And here is the same progression a couple of times through, moving along with different inversions, and substituting Em or G6 for G:

AD/F#EmDA/ED/F#G6D/A
42101234
43100013
44321012

In the charts above, If there is a slash after a chord symbol, and a note after the slash, the note after the slash refers to the lowest note or bass note. These are called “slash chords” and they are a GREAT way to show a bass-line and a chord progression at the same time. No slash just means that the chord is in Root Position with its Root in the bass.
