Hi,
some time ago i watched an interview on TV with the professional piano player Bruno Gelber (one of the best in Argentina, along with Argerich and Baremboin).
He stated that he has 40 hours of piano music in his head !!! That is, he claimed he could sit down on the piano and play by heart 40 hours of music (of course, it would be impossible in practice for obvious reasons, but anyway...).
As a non musician (i am just learning piano), i was very impressed by his claiming.
Question:
could it be true, or was he probably exagerating?
Greetings
