The other great passions of Georgios Kasassoglou, besides music and his
family, were poetry and Ancient Greece.
The antique Greek theatre fascinated him. In close collaboration with
the eminent authorities of his time he wrote incidental music for numerous
tragedies and comedies of Ancient Greece.
He composed ballet music for the dance ensembles of Rallou Manou, Manon
Renieri, and others. Between 1945 and 1955 he worked in close collaboration
with the most significant writers, directors, stage designers and actors
of the time.
He wrote essays, studies about music and reviews for newspapers and magazines,
as well as critical treatises on current musical events.
Avra Theodoropoulou, a renowned music critic of the time, wrote: Kasassoglou
is not the product of a particular school; one could say that he is a
creation of his own. The work of Kasassoglou extends over all musical
forms except opera. Art song is the form that inspires him the most.
