Usually I am skeptical of anything that says "quick and easy" especially when it comes to piano, because many hours of right practice with right instructions, even if however talented, are indispensable for good performance.
Nevertheless, I came to believe the efficacy of applying several tips because many tend to make pieces much harder than they actually are for no or little musical reason, but for lack of understanding of what are really required (and what are totally detrimental).
Those tips are: take your time, constrain your movements, and prioritize. If we apply these right, our performance will be dramatically beautiful, engaging, and solid in a day.
