Suspended chords are notated in shorthand with “sus,” and there are two types: a sus4, and a sus2. If you see a chord symbol that just says “Csus,” the implication is that the chord is a sus4. Starting with a basic C major triad (C–E–G) we simply move the 3 up a half step to the 4 of the scale (in this case, F). You end up with C–F–G, which is shown in Ex. 1. A word to the wise: Break down your major chord shapes and locate the 3. That is the note you need to move up one fret to turn it into a sus4 shape.
