Watch the Suspended Triads Over Changes online guitar lesson by Rob Garland from Chord Navigator: CAGED Triads

Select an area of the neck to play the first chord. Find a C-A-G-E-D shape such as the C shape, 12th fret A string, and play A on the D, G, and B strings. Now look for the next chord Asus4. Move the 3rd (C#) to the 4th D on the D string 12th fret. Continue through the rest of the chords and listen to how closely grouped these chords sound. Let's also do this in another area of the neck on just the G-B-E strings. I'll begin by playing A using the E shape from the note C# (1st inversion) on the G string.
