Notes and Arpeggios
The 7sus4 chord combines the suspended 4th with a b7, 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 complete chord tones are: Bb, Eb, F, Ab. The complete formula is 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, outline the harmony one note at a time. Start from the root and add the chord's actual degrees (4, 5, and b7) as the arrangement allows. The chord-tone boxes locate notes; the ordered arpeggio gives a playable route with explicit position shifts.
Target the root on beat 1 and use degree 5 or the root octave to stabilize the groove. Use the highlights to spot where the same tone repeats across strings.
