"Tratto" was the name Bernd Alois Zimmermann gave to his first piece of music in 1966, realized exclusively by electronic means, which he followed up three years later with Tratto II.
"Strecke, Zeitstrecke, Fahrstrecke, Raumstrecke" or simply "Stelle" could mean the ambiguous Italian title of his composition, which Zimmermann perceived as a running against and into each other of different space and time directions.
Like a neutonic winter journey, he lets sine tone stretches strive towards "an inexorably approaching time and end point".
The listener is offered a compelling sound tableau that "opposes the non-repeatable and irreversible course of events with a persistent moment".
