Teodoro Anzellotti pursued his accordion studies at the Hochschulen in Karlsruhe and Trossingen and quickly achieved victories at various international competitions.
Since the 1980s he has been a regular guest at the major festivals and with leading orchestras. Teodoro Anzellotti has successfully contributed to integrating the accordion into the sphere of classical music. This has occurred principally through his service to New Music: through his development of performing techniques he has enlarged the tone-color capabilities and sonic profile of his instrument. More than 300 new works have been written for Teodoro Anzellotti, by composers such as George Aperghis, Luciano Berio, Brice Pauset, Heinz Holliger, Toshio Hosokawa, Mauricio Kagel, Michael Jarrell, Isabel Mundry, Gerard Pesson, Matthias Pintscher, Wolfgang Rihm, Salvatore Sciarrino, Marco Stroppa, Jörg Widmann and Hans Zender.
