is palm mutein just like a softer version of the note or is it supposed to sound totally different
palm muting is when you place your palm over the strings near the bridge to mute the notes.
It is a just keeping the string from vibrating, giving it a staccato-like sound.
Yeah, its not supposed to change the note but it makes it short and snappy and i guess softer since it the strings arent vibrating. Once you get a feel for it its very easy to do. If you have a strat or strat copy, the volume knobs get in the way but its not so bad.
it fills the song with a chunky like effect, makes it a little bassier so to speak... and it also make a song much cleaner (for punk like music). imagine not palm muting and playin a green day song... noiseehhh
you don't change the note, except if you don't place your hand really close to the bridge
It usually gives a heavy 'chug' sound for metal or, a groovy sound for blues and such. Its a useful technique.
