Bloch was born in Geneva to Jewish parents and began playing the violin at age 9. He began composing soon after. He studied music at the conservatory in Brussels, where his teachers included the celebrated Belgian violinist Eugène Ysaÿe. He then travelled around Europe, moving to Germany (where he studied composition from 1900–1901 with Iwan Knorr at the Hoch Conservatory in Frankfurt), on to Paris in 1903 and back to Geneva before settling in the United States in 1916, taking American citizenship in 1924. He held several teaching appointments in the U.S., with George Antheil, Frederick Jacobi, Quincy Porter, Bernard Rogers, and Roger Sessions among his pupils. See: List of music students by teacher: A to B#Ernest Bloch. In 1917 Bloch became the first teacher of composition at Mannes College The New School for Music, a post he held for three years. In December 1920 he was appointed the first Musical Director of the newly formed Cleveland Institute of Music, a post he held until 1925. Following this he was director of the San Francisco Conservatory of Musicuntil 1930.
In 1941, Bloch moved to the small coastal community of Agate Beach, Oregon and lived there the rest of his life. He taught and lectured at the University of California, Berkeley until 1952. He died in 1959 in Portland, Oregon, of cancer at the age of 78. His body was cremated and his ashes were scattered near his home in Agate Beach.
The Bloch Memorial has been moved from near his house in Agate Beach to a more prominent location at the Newport Performing Arts Center in Newport, Oregon.

Tchaikovsky is considered as one of the most talented Russian composers of the 19th century. Unlike many other Russian composers of his time, he studied at a conservatory and made the western music theory his own. So, he was not as distrustful of western music as the group of nationalistic composers surrounding Balakirev. Yet, Tchaikovsky sought to express the typical Russian mentality just as much and used many Russian folk songs in his music. He had a good relationship with Balakirev, who helped him with constructive feedback on his first masterpiece, the overture of Romeo and Juliet. At times, Tchaikovsky was emotionally unstable, which has often been attributed to struggles with his homosexuality. His decision to marry proved to be disastrous and plunged him into a deep crisis. Yet, the passionate letters of his fiance, even though they barely knew each other, did inspire him to compose his succesful opera Evgenij Onegin. Tchaikovsky had the wonderful gift of composing the most beautiful, lyric melodies. He had a feeling for creating a certain atmosphere in his music and mastered the art of orchestration. Moreover, he excelled in dance music, which made him the ideal composer for ballet. With his ballets The Swan Lake, The Sleeping Beauty, and The Nutcracker he brought the genre to a higher level. During his life, he was already a celebrity. He often did tours to conduct his music and in the USA he was welcomed as a star. He died unexpectedly, nine days after the premiere of his incredibly gloomy Sixth Symphony, probably of cholera. Some other highlights of his body of works are his First Piano Concerto, his Violin Concerto and the Rococo-variations.
