I'm learning "Nightfall" by The Devil Wears Prada, and it has a lot of these "x" in the tab. What is the correct way to play these? I can't seem to find anything on Youtube, but it may be because I don't know what people refer to them as? As far as I can tell it's a soft press down with the fretting hand, to the point where it's just hard enough to produce a sound but not hard enough to produce a note? Essentially a muted note. When I try this I just get a shitty sound, with varying shittiness depending on where on the fretboard I do it. Where should my hand be on the fretboard when playing this and what else am I missing here? Here's the tab: https://drive.google.com/file/d/1bknsk2K4oRi8_z4YcrP4eZPng_WhZDd7/view Any help would be appreciated.
