アニバル・トロイロ
Early in his career Piazzolla played in a number of orquesta típicas, including that of the renowned bandoneonist Aníbal Troilo from 1939. During this period he began to study classical orchestration with Alberto Ginastera, the eminent Argentine composer, and took piano lessons with the Argentine classical pianist Raúl Spivak. Piazzolla combined this with a gruelling performing schedule in the tango clubs at night and between 1944 and 1946 he went on to lead the orchestra of the tango singer and bandoneonist Francisco Fiorentino.
