Telemann took little trips outside of Germany at this time. However, later in the Hamburg period he traveled to Paris and stayed for eight months, 1737 into 1738. He heard and was impressed by Castor et Pollux, an opera by French composer Jean-Philippe Rameau. From then on, he incorporated the French operatic style into his vocal works. Before then, his influence was primarily Italian and German.[6] Apart from that, Telemann remained in Hamburg for the rest of his life. A vocal masterpiece of this period is his St Luke Passion from 1728, which is a prime example of his fully matured vocal style.
