Playing tips

How to play C7sus4 on guitar

Root anchor

Find the root on the low E string at fret 8 before you place the other fingers.

Setup

Place the lowest note first, then stack the rest of the higher-position shape across frets 8 to 10.

Strum path

Let the full strum stay even from low E to high E.

Clearance

Keep each fingertip vertical so the adjacent strings stay separate.

Check

Pick through the strings once before you strum hard, and fix the first dull note you hear.

Position

Check the fret number before each full strum so the whole shape does not drift a fret high or low.
