means, invited Schubert to lodge with him at his mother's house. The proposal was particularly opportune, for Schubert had just made the unsuccessful application for the post of Kapellmeister at Laibach, and he had also decided not to resume teaching duties at his father's school. By the end of the year, he became a guest in Schober's lodgings. For a time, he attempted to increase the household resources by giving music lessons, but they were soon abandoned, and he devoted himself to composition. "I compose every morning, and when one piece is done, I begin another." During this year, he focused on orchestral and choral works, although he also continued to write Lieder. Much of this work was unpublished, but manuscripts and copies circulated among friends and admirers. In early 1817, Schober introduced Schubert to Johann Michael Vogl, a prominent baritone twenty years Schubert's senior. Vogl, for whom Schubert went on to write a great many songs, became one of Schubert's main proponents in Viennese musical circles. Schubert also met Joseph Hüttenbrenner (brother of Anselm), who also played a role in promoting his music. These, and an increasing circle of friends and musicians, became responsible for promoting, collecting, and, after his death, preserving his work. In late 1817, Schubert's father gained a new position at a school in Rossau, not far from Lichtental. Schubert rejoined his father and reluctantly took up teaching duties there. In early 1818, he applied for membership in the prestigious Gesellschaft der Musikfreunde, intending to gain admission as an accompanist, but also so that his music, especially the songs, could be performed in the evening concerts. He was rejected on the basis that he was "no amateur", although he had been employed as a schoolteacher at the time and there were professional musicians already among the society's membership. However, he began to gain more notice in the press, and the first public performance of a secular work, an overture performed in February 1818, received praise from the press in Vienna and abroad. Schubert spent the summer of 1818 as a music teacher to the family of Count Johann Karl Esterházy at their château in Zseliz (now Želiezovce, Slovakia). The pay was relatively good, and his duties teaching piano and singing to the two daughters were relatively light, allowing him to compose happily. Schubert may have written his Marche Militaire in D major (D. 733 no. 1)
