Always brace your thumb against the sixth string or the string you plan to play next for better stability and control. When playing on the sixth string, I place the back of my thumb on the guitar to maintain control.

To develop guitar technique, one must start by ensuring the thumb operates independently from the fingers, allowing for relaxed or active finger movements while the thumb performs different tasks.

The guitar should be positioned correctly to allow for smooth transitions between strings without excessive arm movement, which can reduce accuracy.

To maintain a full range of motion while playing barre chords, position your thumb against your middle finger and rotate outwards instead of pressing your thumb and index finger together.

When you pick something up or tap on a table, you naturally use a relaxed and efficient hand position, which should be mirrored in guitar playing.

Independent training for the thumb and fingers is essential, enabling each to function without affecting the other, which is vital for playing beautifully and accurately. To make a melody sing, you need to control each finger individually and develop a relationship between them, allowing for independence and trust in your playing.

The rotational force of your hand is crucial for pressing down barre chords effectively, with your thumb acting as the rotational axis.

Be mindful of finger placement on the fretboard; pressing too far back can cause buzzing and requires more energy to produce a clean sound, so aim to keep fingers close to the fret.

It's crucial to keep the right hand relaxed, as if holding a golf ball, to ensure fluid movement while playing.
