Heiner Ruland

Born on 6 April 1934, in Aachen, Ruland studied chemistry after a humanistic secondary school education, then school music with harpsichord as main subject with Fritz Neumeyer in Freiburg im Breisgau. From 1963 to 1974, he worked as a music teacher at the Waldorf School Benefeld, Lüneburg Heath.^{[citation needed]}

Based on Kathleen Schlesinger's research and Rudolf Steiner's suggestions, intensive musical-anthroposophical research work developed alongside teaching, as laid down in Ein Weg zur Erweiterung des Tonerlebens : musikalische Tonkunde am Monochord^[1] In the course of this musical-humanistic research, an extensive teaching and lecturing activity began. His work as a composer in an expanded tonal system became increasingly important. From 1976 to 2001, he continued to work full-time in the practice of Music therapy at the Öschelbronn Clinic, a hospital for internal diseases.^[2]

Ruland died in Hamborn, on 25 March 2017, aged 82.^[2]
