During these years, he wrote a one-act opera A tale on... (Russian: Сказание про... – Skazanie pro...) based on the work of Semyon Kirsanov.

In 1973 Korndorf completed post-graduate studies with his opera Feast in the Time of Plague based on the play of the same name by Alexander Pushkin.

Later, he turned to a kind of minimalist repetitive aesthetic, notable in his Confessiones (1979) for double bass and twelve wind instruments, and in Jarilo (1981) an extensive piece for piano and tape.

In 1991 Korndorf left Russia for Vancouver, British Columbia, Canada, where he began experimenting with electro-acoustic media.
