A#7sus4 – La# Seventh Suspended Fourth
In music theory, A# seventh suspended fourth chord is built on A#-D#-E#-G# formation: root-perfect fourth-major second-minor third. This seventh suspended fourth chord has a formation A#-E#-G#-D#-E# 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.
