The Tonhalle is a concert hall in Zurich, home to the Tonhalle-Orchester Zürich, one of Switzerland's leading orchestras.

[10] In 1939, the building was changed to a Kongresszentrum for the Swiss National Exhibition of 1939 [de] by the architectural firm Haefeli Moser Steiger.

[15] Major renovation works on the hall began in 2017,[16] which included the removal of the old organ and installation of a new one[17] built by the firm Kuhn.

[19][20] The Tonhalle Series grew increasingly abstract and focused on the feelings of the music.

[21][22] Müller-Brockman used a visual form to translate the mathematical system that is found in music, playing with visual scale, rhythm, and repetition, while trying to stay true to each musicians composition who was featured on the poster.
