to dynamically alter sounds from the instrument...use a pick at different angles (tonal variations also),and fingers to create a wider palette of sounds. As you pick along the length of a string the tone varies quite astonishingly. Play at the bridge and then up at the neck pickup and you will be able to extract some amazing sounds. Like how we really never take to a monotonous sound,it either puts you to sleep or fades to the back recesses of your mind...vary dynamics as you play. Play like you speak,softly then louder,laid back and then with some urgency as circumstances and variable around us change. What I am saying here is please react to stimuli and do not play by rote and repetition only,its an extension of your mind so do not treat it any different :)
