An Interesting Way to Start Worship Songs

Here I go over a cool progression for beginning worship songs. It is as follows:

1 7 4_{major(third inversion)}/6 1 5_{major(third inversion)}/7 5

E.g. In the key of D_♭, suppose your song starts with the 1 chord D_♭major(add 9), you can preceed it with the progression by playing

D_♭ C G_{♭major(third inversion)}/B_♭ D_♭ A_{♭major(third inversion)}/C A_♭ D_♭major(add 9)

Below is a recording.
