Big ups to the MI, I know what ghost notes are, but by trying to explain them over the internet, I probably won't be able to fully explain them to where you get the full picture, so heres my recomendation. Go to vicfirth.com and head to dom famularo's cyber lessons, he breaks it down to the T. If your pc isn't able to stream the video clearly, then heres how i can say it without gettin all technical and breaking down the actual stroke. Basically, ghost notes are softly played notes, often played on the snare, that fill in the open spaces of grooves, for example you can play triplettes with the 1 being play on the hats and the 2 and 3 being played softly on the snare and using that as a connective tissue for a groove. Hope this helps somewhat.
