Decide exactly what it is you want to do in the first place and how you will do it; then play it. Stop and think if you played it in the way you meant to do. Then, only if sure of this, go ahead. Without concentration, you can do nothing. The brain must guide the fingers, not the fingers the brain.
—  Theodor Leschetizsky

The house in Łańcut, Poland where Theodor Leschetizky (1830 - 1915), arguably the most celebrated piano pedagogue and father of the “school of weight” and the “golden sound,” received lessons from his father and later schooled his first pupils as a teenager. Among his most famous students were Schnabel, Paderewski, and Wittgenstein. (ph: B. Dubiel)
