All of the songs you have played so far have involved a downward pick motion. The common symbol for a downstroke looks like this t. Notice that the left side of the picking symbol is thicker than the right side. Do not confuse the picking symbol with the strum symbol t (for strumming chords). With the introduction of eighth notes, the technique of down and up (s) picking is used. This is called alternate picking, and is essential for the development of speed and accuracy. In alternate picking, use a down pick on the beat (the number count) and an up pick off the beat (the "and" count).
