The following progression uses movable four note voicings on the first four strings. It is played with a rhythm using sixteenth notes (four notes per quarter note beat). If you are not familiar with sixteenth note rhythms, see Complete Learn to Play Rhythm Guitar Manual.
A suspended chord can be created by substituting the 4th degree of a chord for the third. For example, a C major chord contains the notes C, E and G, (1, 3 and 5) while a C suspended chord contains C, F and G, (1, 4 and 5). The following diagrams show some common open suspended chord shapes.
