Suspended chords add a nice change to the usual 7th or minor 7th chords. I cover the dominant 7th suspended chord for G and the common extensions: G7sus, G9sus, and G13sus. There are 4 different major scales that build a G7sus chord, as well as 1 scale degree from the harmonic minor and 2 from the melodic minor.
Suspended 7th chords are common in popular music and sound great. There are 51 open 7sus4 guitar chord shapes build on notes from the key of C major in this article. I cover the intervals and notes in each chord type and list popular song examples and how to use the chords. The specific chords are 7sus, 9sus, 13sus & 7susb9.
