Palm muting is a guitar technique that involves muting the strings with the palm of the picking hand. This creates a percussive, muted sound that is often used in rock, metal, and punk music. To palm mute, simply rest the edge of your palm on the strings near the bridge of the guitar. The amount of pressure you apply will affect the sound of the palm mute. Lighter pressure will create a more subtle muting effect, while heavier pressure will create a more pronounced muting effect.
Palm muting is a versatile technique that can be used to create a variety of different sounds. It can be used to add rhythm and texture to a song, or it can be used to create a more aggressive sound. Palm muting is also a great way to practice your picking accuracy and control.
