This is not scientific. It's just something I've noticed lately that I do. I've been doing lots of pad work in the past 6-8 months. I've noticed that as a pattern becomes fluid and comfortable where I don't have to count or think about it, the pattern develops its own soundtrack in my head. It isn't random either. The next time I get out the pad and play the same pattern, it's song returns. So basically, my head makes up a melody to help my hands remember the pattern. Does this make sense at all? Am I the only one?
