The Gb sus 4 chord (G flat suspended 4) contains the notes Gb, Cb and Db. It is produced by taking the 1 (root), 4 and 5 of the Gb Major scale. It is essentially a Gb Major chord, with the 3rd (Bb) taken out and the 4th (Cb) added in.
By omitting the 3rd and adding the 4th, the chord feels ‘suspended‘. The 4th creates a feeling of tension, which feels resolved when the chord moves to the standard Major chord (bringing the 3rd back in). To demonstrate this, try the following chord progression:
Gb Major – Gb sus 4 – Gb Major
Just by strumming those three chords once each, you will hear the the tension that is created by moving to the Gb sus 4 chord. You will also hear the resolution that is created by moving from the sus chord back to the Major chord.
Gb sus 4 is often used as a way of adding flavour to the Gb Major chord. The G flat sus 4 chord is often substituted momentarily, when playing the Gb chord, to create a quick sense of musical movement and interest.
