At the beginning of the 20th century, the musician Gertrud Grunow had developed her own theory of music education, which dealt with the equitable, harmonious use of all the senses. Her 'theory of harmonisation' course at the Bauhaus was so popular that it was attended by students and masters alike.
The musician Gertrud Grunow was born in 1870 in Berlin. As early as 1914, Grunow was exploring the fundamental relationships of sound, colour and movement. In 1919, she held her first lectures on these topics in Berlin. From 1919 to 1923, she taught her course on the Theory of harmony at the Staatliches Bauhaus in Weimar. She continued her teaching activities from 1926 to 1934 in Hamburg and subsequently worked for several months in England and Switzerland before returning to Germany during the war. Gertrud Grunow died in Leverkusen in 1944.
