 Until he coined the term "symphonic poem", Liszt introduced several of these new orchestral works as overtures; in fact, some of the poems were initially overtures or preludes for other works, only later being expanded or rewritten past the confines of the overture form.The first version of "Tasso", Liszt stated, was an incidental overture for Johann Wolfgang von Goethe's 1790 drama "Torquato Tasso", performed for the Weimar Goethe Centenary Festival.
