The GSUS4 chord is a three-note chord consisting of the fundamental G, the fourth C, and the fifth D. This chord is usually labeled GSU4, where "G" indicates the root note of the chord and "SUS4" indicates that there is a fourth in that chord.
Root -g:The fundamental note is the fundamental tone of the chord and determines the name of the chord. In the GSUS4 chord, the fundamental note is the g, which is the basis of the chord.
Fourth: -c:The fourth note is the note that counts four degrees upwards from the root note. In the GSUS4 chord, the fourth note is C. This note gives the chord a sense of suspension as it replaces the third note that normally belongs to a major or minor chord.
Fifth -d:The fifth note is the note that counts five degrees upwards from the root note. In the GSUS4 chord, the fifth note is D. The presence of a fifth note adds a sense of stability to the chords while creating a harmonious acoustics with the root and fourth notes.
GSUS4 chords are often used in **, especially in creating the emotion of suspension and resolution tones.
