My style is a combination of what I think of as two different approaches: "pattern focused" and "melody focused."

Pattern focused is where I am always playing a pattern (but not always the same one) and fitting the melody notes into it. Results are highly syncopated. Yes, there are "filler notes" but I use a pattern that makes then sound "right" and pleasing to my ears.

Melody focused is where I start by picking all or most of the melody notes with the "correct" durations. Then I try to figure out where I can sneak patterns in. Much less syncopated but still pleasing to my ears when I do it "right."
