The 7sus4 chord quality is a type of seventh chord that has a suspended fourth instead of the third note. In a typical seventh chord, the sequence of notes includes a root, major third, perfect fifth, and a minor seventh. However, in a 7sus4 chord, the major third is replaced with a perfect fourth, resulting in a unique and less resolved sound. This suspended chord is often used to create a sense of tension that typically resolves to a more stable chord, like a dominant seventh (7) or major chord. Guitarists will appreciate its application in genres ranging from rock to jazz, where it serves as a versatile harmonic tool to enhance progressions with colorful dissonance.
