Welcome to your comprehensive guide on the A7sus4 Guitar Chord, a sonority that adds a unique flavor to your guitar playing.

This unique combination of intervals—Root, Perfect Fourth, Perfect Fifth, and Minor Seventh—defines the characteristic sound of the A7sus4 chord. It’s crucial to grasp that the “sus4” indicates the suspension of the third degree of the scale, replaced by the fourth, and the “7” signifies the presence of the minor seventh interval, classifying it as a dominant seventh type chord but with a suspended sound. For a deeper understanding of chord construction using intervals, exploring resources on building chords through stacked intervals can be highly beneficial.
