 At the conservatoire, Delius made little progress in his piano studies under Carl Reinecke, but Salomon Jadassohn praised his hard work and grasp of counterpoint; Delius also resumed studies under Hans Sitt.Delius's early biographer, the composer Patrick Hadley, observed that no trace of his academic tuition can be found in Delius's mature music "except in certain of the weaker passages".Much more important to Delius's development was meeting the composer Edvard Grieg in Leipzig.
