Doksari - comprehend bowing art
The Doksari - comprehend bowing art framework is formed by the collaborative projects led by Vasileios Chatziioannou and Montserrat Pàmies-Vilà on the acoustics of bowed string instruments. "Investigating cello sound production beyond ordinary bowing" is a project within the Hertha-Firnberg Programme that was granted to Montserrat Pàmies-Vilà in 2021. "The bowed string" is a stand-alone project led by Vasileios Chatziioannou that begins in April 2022. Both projects are funded by the Austrian Science Fund FWF.
Doksari aims at the analysis of playing techniques in bowed-string instruments. In 2020, IWK acquired a robotic arm that would serve at reproducing the excitation of musical instruments, and it is thus the central element of the Doksari framework as we know it today. Alexander Mayer has been adapting the setup to the needs of the research, including a custom-built clamp system and a real-time data exchange RTDI connection. With this setup, bowing actions recorded using optical Motion-capture technology will be reproduced in repeatable conditions. In 2022 the team grew with two more researchers, Ewa Matusiak (PostDoc) and Alessio Lampis (PreDoc), as well as the cellist and master student Anna Scheiblauer.
