D#7sus4 - Re# Seventh Suspended Fourth

In music theory, D# seventh suspended fourth chord is built on D#-G#-A#-C# formation: root-perfect fourth-major second-minor third. This seventh suspended fourth chord has a formation D#-A#-C#-G#-A# from basses to trebles in the guitar.

This suspended chord is derived from a seventh chord. In music theory, dominant seventh chords are built by four different notes such as C-E-G-Bb. The seventh suspended fourth chords substitute the minor or major third interval with a perfect fourth interval above root note(C-F-G-Bb). This change gives a dissonance and delaying effect before resolving of harmonic chords.
