F#7sus4 - Fa# Seventh Suspended Fourth

In music theory,
F# seventh suspended fourth chord is built on
F#-B-C#-E formation: root-perfect fourth-major second-minor third. This seventh suspended fourth chord has a formation
F#-C#-E-B-C#-F# 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.
