Een van de door William Caplin onderscheiden Conventional Theme Types. Afkomstig van de Duitse term “Periode”.
Definition from Caplin ACF:
“The period (like the sentence) is an 8-m. theme built out of two phrases: a 4-m. antecedent phrase, followed by a 4-m. consequent phrase. The labels for these phrases also refer to the two formal functions of the period: an initiating antecedent and a concluding consequent.
Antecedent Phrase
An antecedent phrase begins with a 2-m. basic idea (just like in the sentence), followed by a 2-m. contrasting idea leading to a weak cadence, usually a half cadence (HC) but sometimes an imperfect authentic cadence (IAC).
Consequent Phrase
The consequent phrase repeats the antecedent by bringing a return of the origi- nal basic idea. A contrasting idea, which may or may not resemble the one in the antecedent, leads to a stronger cadence, usually a perfect authentic cadence (PAC), or more rarely an IAC (if the antecedent ended with an HC).”
