what do you do to mute a note? is it the same as palm-muting or is it some kind of harmonic thing (which i wouldn't understand because im retarded)?

Regular mutes are played by laying whatever fingers on your fretting hand across the strings you want to mute, without pressing the strings down. Playing harmonics is similar, but in playing harmonics you need to place your finger on a specific place above the fret and release your finger as soon as it's picked.
