How can I learn how to play dead notes on the guitar?

To learn how to play dead notes on the guitar, you can start by lightly resting your fretting hand fingers on the strings without pressing down to produce a clear note. Practice muting the strings with your picking hand while strumming or plucking to create the dead note sound. Experiment with different hand positions and pressures to control the level of deadening. Practice regularly to improve your technique and control over dead notes.
