Input: As tempting as it can be to think of Liszt as the father of modern music on the basis of his late music, looking at his achievements in these works as ends in themselves would be erroneous. Liszt's technical achievements in his late music are one side of a more complex picture. Along with the increasing interest in Hungarian and other national schools of composition already mentioned, essential parts of this picture are tragedy in Liszt's personal life and developments in his friendship with Wagner. In _his_ later years Liszt's problems with health, both physical and mental, affected his ability to complete compositions. <sep>, Pronoun: his <sep>, A: Wagner <sep>, B: Liszt
