How do binary and ternary forms organize a whole piece into sections?

Topic 8.4 Binary and Ternary Form: identify binary (AB), rounded binary, and ternary (ABA) forms by their sections, key scheme and returns of material.
A focused answer to AP Music Theory Topic 8.4, covering binary form (two sections, often with a modulation), the difference between simple and rounded binary, ternary form (ABA with a returning A), the typical key schemes, and how repeats and returns define each form, with a worked analysis.

How do melodic and harmonic sequences restate a pattern at successively different pitch levels?

Topic 8.3 Melodic and Harmonic Sequence: identify melodic sequences and the common harmonic sequences (descending fifths, ascending and descending stepwise) by their repeating pattern and interval of transposition.
A focused answer to AP Music Theory Topic 8.3, covering the sequence as a pattern restated at a new pitch level, melodic versus harmonic sequences, the common harmonic sequence types (descending circle of fifths, ascending and descending stepwise), the interval of transposition, and diatonic versus real sequences, with a worked identification.

What are the diatonic modes, and how does each one differ from major or minor?

Topic 8.1 Modes: identify and construct the seven diatonic modes by their characteristic altered scale degrees and their final.
A focused answer to AP Music Theory Topic 8.1, covering the seven diatonic modes (Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, Locrian), how each is built on a different degree of the parent scale, the characteristic altered degrees that give each its color, and finding a mode by its final, with a worked construction.

Beyond binary and ternary, how do strophic, through-composed and other structures organize music?

Topic 8.5 Other Common Formal Structures: identify strophic, through-composed, theme and variations, and compound forms, and analyze how a whole piece is organized.
A focused answer to AP Music Theory Topic 8.5, covering further formal structures (strophic, through-composed, theme and variations, and compound forms such as the minuet and trio), how each organizes repetition and contrast, and how to analyze the overall form of a piece, with a worked analysis.

How do phrases relate to form periods, and how are motives transformed?

Topic 8.2 Phrase Relationships and Motivic Transformation: analyze phrases, periods (antecedent and consequent), and the transformation of motives.
A focused answer to AP Music Theory Topic 8.2, covering the phrase as a unit ending in a cadence, antecedent and consequent phrases forming a period (parallel and contrasting), the motive as a short idea, and motivic transformations (repetition, sequence, inversion, augmentation, diminution), with a worked analysis.
