My favorite piano Quote

by Delano Douglas
(Spanish Town, Jamaica)

Frederic Chopin once said that Simplicity is the highest goal, achievable when you have overcome all difficulties. After one has played a vast quantity of notes and more notes, it is simplicity that emerges as the crowning reward of art.
And Robert Schumann once said that If you play, never minds who listen to you.

So both of them that means here is the deal,
In order to take an advantage of incredible exercises, you must be able to read music.
