Tchaikovsky met some famous musicians including the French composer Berlioz who was visiting Moscow. He also became friendly with the Russian composer Mily Balakirev who was very helpful and persuaded him to rewrite one of his works several times until it was very good. he result was a piece for orchestra called "Romeo and Juliet" which soon became internationally known. Balakirev had four friends who were composers. This circle of friends is often called “The Five” or “The Mighty Handful”. They were interested in using Russian folktunes in their music. Tchaikovsky was never a member of the group, although he liked their ideas. Tchaikovsky was different to them: he had learned music at the Conservatoire where he had studied Western music. The harmonies that he used in his works were often not suitable for Russian folktunes. He wrote many songs which are romantic in character. One of them, "None But the Lonely Heart", is especially well known in English.
