Notes and Arpeggios

The 7sus4 chord combines the suspended 4th with a ♭7, delaying the resolution even further than a regular sus4 by keeping the dominant tension alive. It's a common sound in pop, gospel, and fusion for building anticipation before a payoff. The chord tones are: Bb, Eb, F, Ab. It's built from degrees 1, 4, 5, and b7.

How to Use It

Sus chords are everywhere in pop, rock, and worship-style progressions for "lift" and suspense. On bass, you usually outline this chord instead of strumming it: emphasize the root, 3rd, 5th, and 7th as the harmony requires, then use passing tones to connect back to the groove.

Play root and 5th on strong beats, then add the 3rd or 7th to make the chord quality clear. Use the highlights to spot where the same tone repeats across strings.
