Any kind of learning process could be seen as a spiral;
you will learn a certain amount of things on a basic level that will be
repeated again and again as you progress on more advanced levels.
steps could be seen as a first swirl around that spiral…!
said, I am not trying to present a one-solution-to-all progress; because
that would be impossible.
Even though core elements in the process are the same
in many ways of teaching and learning the piano, something that works for one person
simply does not mean that it would work for another.
So, here is
just one way of looking at a step by step plan for learning the piano.
Spend as much time as you need on each step and make sure to master each before moving to the next.
And do enjoy yourself!
