(Ger.: ‘pull’, ‘draught’, ‘stress’, ‘procession’, ‘progression’)
In Schenkerian analysis (see Analysis, §II, 4), a conjunct diatonic succession of notes, encompassing a certain interval, by which movement from one pitch, register or part to another is established; hence one of the chief methods of Prolongation of a basic musical structure. As a technical term, Zug is usually translated as ‘progression’ or, more precisely, as ‘linear progression’. In identifying these progressions in Schenkerian analyses, the interval forms part of the name, thus Terzzug, Quartzug, Quintzug, Sextzug, Septzug, Oktavzug (‘3rd-progression’, ‘4th-progression’, ‘5th-progression’ etc.).
At the most basic level of an analysis, the background Layer, the function of a Zug is to connect the fundamental upper voice ( Urlinie) with an inner voice. In ex.1, for instance, the Terzzug d″–c″–b′ delays the completion of the Urlinie movement to c″. Because this progression prolongs a note in the Urlinie itself, it is called a Terzzug erster Ordnung (‘3rd-progression of the highest order’)....
