Epäklassisia
Epäklassisia is a Finnish term used to describe works that lie outside the Western classical tradition.

The word combines the prefix epä- (not) with klassinen (classical), signaling a departure from established Classical-era
As a label, epäklassisia covers a wide range of practices, including improvisation, chance elements, non-traditional instrumentation,
Non-classical music, classical music, contemporary music, avant-garde.
