The "Great Syntagmatics of Film" by Christian Metz interprets the feature film as reducible to autonomous segments, that are separated into autonomous shots and syntagmas, whereby the latter can be separated into non-chronological syntagmas (sequence of parallel montage) and chronological syntagmas. Within these is again differentiation between descriptive and narrative syntagmas, whereby the narrative syntagmas are divided into alternating syntagmas and linear narrative syntagmas (the linear narrative syntagmas are thereby divorced in scene and sequence). The shot-countershot-technique is a typical linear narrative syntagma..Peter Tscherkassky
