The last quarter of 2021 held something special for me: the start of my new research project “Performers as Commissioners of New Music in the Twentieth Century: Preconditions, Self-Conceptions, Impacts.” It is funded by an Elise Richter Grant (with a volume of € 379,095.37) from the Austrian Science Fund (FWF) and runs from October 2021 to September 2025 at the University for Music and Performing Arts Vienna. As a follow up to my work on Benny Goodman, this study includes further artists, who essentially shaped their instruments’ repertoires and aesthetics by hiring composers to write for them (see below), and takes the questions investigated within the Goodman-pilot onto a broader level.
