Alternate picking arpeggios
At slower tempos using alternate picking to play arpeggios can provide some real advantages in terms of improving the overall feel and dynamics. The most economical way to play notes on adjacent strings is with a single stroke of the pick - an ascending arpeggio would be played with all down strokes, and visa versa. At slow tempos however it is difficult to maintain even timing when picking this way - it can become ‘lumpy’. The alternate picking technique improves timing at slow to medium tempos because it adds a mechanical, pendulum style movement to the picking hand. The constant movement of the picking arm up and down also helps retain a consistent dynamic and you will find it easier to accent notes in a musical way with this technique. The hardest thing to master is consistency, as the pick will often be skipping strings when playing more complex patterns. The best plan is to start very slowly and be strict with yourself. The alternate picking regime of down up, down up needs to be maintained if you are to reap the full benefits of using this technique.
