 Liszt constructed compositions with varying sections of music not necessarily having distinct beginnings and ends.He sketched sections, sometimes without fully completing them, on a small number of staves with some indication of the orchestration.After an assistant—August Conradi from 1848 to 1849, Joachim Raff from 1850 to 1853—had realized Liszt's ideas and provided a score of an acceptable standard, Liszt would then make further revisions; he moved sections to form different structural relationships, and modified connective materials or composed them anew, completing the piece of music.
