Sus chords (eg., from bottom to top, C – F -G) omit the third of the chord and substitute a fourth. They have a broad application to both contemporary and traditional worship styles. They provide a colorful alternative to the standard dominant seventh which occurs frequently in hymn and chorus cadences. They are valuable in creating segues and in effecting modulations in the free-flowing praise format. They are eminently playable on both guitars and keyboards. We’ll look at how the sus4, sus7, and sus9 chords function.
