High Quality Content by WIKIPEDIA articles! A symphonic poem or tone poem is a piece of orchestral music in a single continuous section (a movement) in which the content of a poem, a story or novel, a painting, a landscape or another (non-musical) source is illustrated or evoked. The term was first applied by Hungarian composer Franz Liszt to his 13 works in this vein. A symphonic poem is different from a concert overture, (a form from which it may be regarded as an evolution), which may also be illustrative in nature, in that it aims at an enlarged musical and emotional range and scope. As musicologist Hugh Macdonald wrote of Liszt's works in this genre, the intent was "to display the traditional logic of symphonic thought;" that is, to display a comparable complexity in the interplay of musical themes and tonal 'landscape' to those of the Romantic symphony. In its aesthetic objectives, the symphonic poem is in some ways related to opera; whilst it does not use a sung text, it seeks like opera a union of music and drama.
