The mind of the performing artist must be as cultured as that of the composer. Culture comes from the observation of many things: nature, architecture, science, sculpture, history, men and women, poetry. I advise aspiring pianists to read a great deal of poetry!
Wise words from Teresa Carreno, one of the greatest lady pianists of the past! As a child she met Liszt himself, who urged her to be true to her own individuality while pursuing her piano studies.
