- Periods: Periods are specific types of phrase relationships where two consecutive phrases form a complete musical thought, usually consisting of an antecedent phrase followed by a consequent phrase.
- Antecedent Phrase: An antecedent phrase is the first half of a period, typically ending with an unresolved cadence. It sets up expectations for the following consequent phrase.
- Consequent Phrase: A consequent phrase is the second half of a period, usually resolving the melodic and harmonic tension created by the antecedent phrase. It provides closure to the musical idea established in the antecedent.
