Another important milestone on the way to Audanika is David Gatzsche's diploma thesis. In 1998, the latter devoted himself entirely to music and studied guitar at the Hochschule für Musik Franz Liszt Weimar. In his diploma thesis in 2004 he further developed the system of his father Andreas Gatzsche. Er bringt Farbe in die bis dahin schwarzweißen Kreise und entwickelt Vorschläge, wie man das System Kindern im Musikschulunterricht näherbringen kann. His brother Gabriel, a media technologist, advises him.
