Ernest Bloch was a Swiss-born composer who marched through the worlds of avant-garde Jewish art or concert music and the Western classical tradition. Bloch's music exemplifies several post-Romantic influences, including the styles of Richard Strauss, Claude Debussy, and Gustav Mahler. His interest in Claude Debussy's and Maurice Ravel's chromatic sounds is apparent in his tone poem Hiver-Printemps. Block wrote a large group of works about Jewish subjects, including the Israel Symphony, Trois poèmes juifs for orchestra, the tone poem Schelomo for cello and orchestra, and the suite Baal Shem for violin and piano. The full maturity of his musical application of Jewish themes and the liturgy is demonstrated in his sacred service Avodath Hakodesh for chorus, baritone, and orchestra. Bloch's works show a strong neoclassical trend that combines musical forms of the past with techniques used in the 20th century. His Concerto Grosso No. 1 and his Piano and string quintet, which use fourth color tones and enhance the emotionally intense nature of music, have been some examples.
