Oh boy, you don't want to open that can o' worms. Because what will be considered great? Horowitz playing Scarlatti with precision? Yuga Want playing a monster Liszt kuncklebreaker? Gieseking playing a delicate Debussy number?
Artistry? Phrasing? Or just NPS (notes per second)? Does a flubbed note rule one out of the running (Cortot, Rubenstein)?
I need to just stop.
It’s how I feel about musical theater songs. If only a performer or two on the planet can perform it decently, it’s close to useless.
Any competent player with sensitivity and a strong piece from either oeuvre can make magic with what I suggest.
