To make a half bar, first raise your hand and form an 'okay' sign with your index finger, placing its tip on the pad or crease of your thumb, then collapse the tip joint backwards to load pressure on the middle joint for better leverage.

A full bar should be laid across one single fret as straight as possible, evenly pressing down across all strings to avoid muting notes.

When playing a bar, lean your index finger slightly to the side to utilize the bonier edge for better pressure distribution, which helps achieve a cleaner note.

Remember that a bar is more about pulling the guitar against your chest rather than squeezing it, allowing gravity to assist in applying pressure with your left arm.

To improve your bar sound, move your elbow down and out to stack your arm, wrist, and hand, creating a more powerful position for pressing down.

Practice a quantity of bars rather than focusing solely on quality; aim for dozens of bars in practice to benefit from both quantity and quality approaches.
