When he returned to Brno he became engaged to his piano pupil Zdenka Schulzová who was only 14. She was still under 16 when they married. Janáček founded (started) an organ school in Brno. He was the director of this school. He also taught music at the Old Brno Gymnasium. His marriage was unhappy and, although they remained married all his life, they spent a lot of time separated. He went on a journey to northern Moravia to collect folk songs which he used in some of his dances for orchestra.
