Hello,I've been playing piano for about 5-6 years before I stopped for an entire year due to my mothers sickness. She is all better now, and I would love to get back into playing piano.I've started playing some new music again, but the only thing i'm playing on the piano is the notes. I have completely forgotten every thing, such as what tempo, dynamics, 2/4th beats...What should I do to revive my skills?
