Playing tips

How to play A7sus4 on guitar

Root anchor

Find the root on the A string before you place the other fingers.

Setup

Set the fretted notes first, then confirm the open strings still ring before the full strum.

Strum path

Start the strum from the A string so the low E string stay out.

Open strings

Keep the A, D, G, and high E strings clear; those open notes belong in the voicing.

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.

Why A7sus4 works
