In the sphere of piano performance or piano artistry there are few human activities where the necessity for extraordinary physical prowess is so closely aligned with the greatest intellectual and emotional capacities.
The virtuoso must possess a memory capable of maintaining thousands of pages of music in the mind and fingers, under the stress and distractions of public performance; the virtuoso must be cultured and self-aware, musically able to convey the great range of meaning embodied within a chosen repertoire; the virtuoso must project both physical excitement and emotional communication; and the virtuoso must experience life to the fullest while remaining cloistered with an instrument in a relentless quest to maintain his or her craft at its highest level.
A capricious, even morbid, temperament is demanded, and there must be the fire that kindles and the power that menaces; a fluctuating, wavering rhythm yet a rhythmic sense of excessive rectitude; a sensuous touch, yet a touch that contains an infinity of coloring; supreme musicianship-Chopin was a musician first, poet afterwards; a big nature overflowing with milk and honey; and, last of all, you must have suffered the tribulations of life and love, until the nerves are whittled away to a thin sensitive edge and the soul is aflame with the joy of death’
Johann Sebastian Bach
Frédéric François Chopin
