The edge of the pick is dragged either down or up along the lower strings to produce a scraped sound.
Turn the volume control down, sound the note(s) and then turn the volume up for a smooth fade in.
The numbers in the traditional notation refer to the fingers required to play each note.
Any kind of fingerpicking requirements are shown at the bottom of the tab notation.
Pick hand tapping
