Tiempo was born into a musical family in Caracas, Venezuela, in 1972. He took piano lessons from his mother, Lyl, at age two. At three he gave his first public recital and a year later played on Argentinian television. He was seven when he made his debut in London, where he walked off with several prizes at the 1980 Ealing Music Festival, one for most talented performer.
Thereafter, Tiempo enjoyed an excellent musical education, with some of the finest piano teachers: Tessa Nicholson, Pierre Sancan
, Maria Curcio, Michel Béroff
, and Alan Weiss. He also studied with Murray Perahia
, Fou Ts'ong
, and Dmitri Bashkirov, all at the Fondazione per il Pianoforte in Como, Italy. In addition, Martha Argerich
and Nelson Freire
have served as mentors to Tiempo, often helping him in his career.
