What the course covers

The first year of college music theory, built on the College Board framework: eight units that move from pitch, rhythm, scales, keys, and intervals through triads and seventh chords to 18th-century four-part voice leading, predominant function, six-four chords, embellishing tones, secondary dominants and leading-tone chords, modes, and phrase form. Every unit trains the exam's four skill categories together: analyzing music you hear, analyzing music you read, converting between the two (dictation, sight-singing, error detection), and completing music from cues (figured bass, Roman numerals, bass-line harmonization). Practice mirrors the exam: four-choice aural and score-analysis sets, melodic and harmonic dictation, part writing scored with the official point-per-chord and point-per-connection method, melody harmonization, and sight-singing.

    Modes and Form

    The seven diatonic modes (Ionian through Locrian) heard and notated, phrase relationships labeled with letters (a a, a a', a b), antecedent-consequent periods (parallel and contrasting), and the common section names (introduction, verse, chorus, refrain, bridge, interlude, coda, codetta) the exam uses to point students to parts of an excerpt. (About 10 to 11 class periods.)

The exam, part by part

4 parts, 2 h 40 min in all.

  • Section I, Part A: Multiple Choice (Aural)

    Questions
    42
    Time
    45 min
    Weight
    25%
    Format details

    Officially 41 to 43 questions in about 45 minutes, every one with a recorded stimulus heard through a wired headset in Bluebook; the audio paces the section. Items are either individual ("read all the answer choices, then listen to the music 2 times") or sets of 4 to 6 questions on one excerpt, with reading time before the audio and several playings, and some sets give timestamps for parts of the excerpt. About 8% of all multiple-choice questions are error detection: compare a printed score with a performance that differs in pitch or rhythm. Excerpts span baroque, classical, romantic, late 19th or 20th century, and contemporary (world music, jazz, pop), instrumental and vocal. Four answer choices (A to D). The CED gives 45% for Section I as a whole; the 25/20 split here is proportional to question count, since every multiple-choice question is worth the same.

  • Section I, Part B: Multiple Choice (Score Analysis)

    Questions
    33
    Time
    35 min
    Weight
    20%
    Format details

    Officially 32 to 34 questions in 35 minutes with a printed score (on screen in Bluebook) as the stimulus and no audio: mostly sets of 4 to 6 questions on one excerpt (often a multi-staff score with figured bass or a transposing instrument) plus a few individual items. Asks for Roman numeral and figured-bass analysis, nonharmonic tones, six-four types, cadences, tonicization, texture, rhythmic devices, key relationships, and notation facts. Four answer choices. Section I overall: about 48% of questions assess analyzing performed music, 44% analyzing notated music, 8% converting between them (error detection); Complete Based on Cues is not tested in multiple choice.

  • Section II, Part A: Free Response (Dictation and Written)

    Questions

    Format details

    Task types: Melodic Dictation, Harmonic Dictation, Part Writing from Figured Bass, Part Writing from Roman Numerals, Harmonizing a Melody

    Always the same seven questions in the same order: Q1 and Q2 Melodic Dictation, Q3 and Q4 Harmonic Dictation (together about 25 minutes, paced by the audio in Bluebook), then 45 self-paced minutes for Q5 Part Writing from Figured Bass (suggested 15), Q6 Part Writing from Roman Numerals (suggested 10), and Q7 Harmonizing a Melody (suggested 20), in any order. Prompts and staves are in a paper booklet; answers are handwritten in it. A mock exam should draw exactly 2, 2, 1, 1, 1 of these types.

  • Section II, Part B: Sight-Singing

    10%
    Format details

    Task types: Sight-Singing

    Two brief, primarily diatonic melodies of about 4 to 8 bars, printed in the booklet. In 2025 and 2026 they were each 4 bars, one in treble clef and one in bass clef, one major and one minor, one simple and one compound meter, marked Moderato and forte with phrase slurs. For each: the starting pitch is played, then 1 minute 15 seconds of practice (singing aloud is encouraged, writing on the music is allowed), then 30 seconds to perform, recorded in Bluebook. Letter names, solfege, scale-degree numbers, or a neutral syllable are all acceptable; students may transpose to a comfortable key; no metronome, instrument, or other device. Restarting is allowed but costs the flow point. About 10 minutes for both.

How the 1 to 5 score is set

Section I: 75 four-choice multiple-choice questions, one point each with no penalty for wrong answers, together 45% of the composite. Section II, Part A: seven free-response questions with raw totals of 9, 9, 24, 24, 25, 18, and 9 points, weighted together to 45%. Section II, Part B: two sight-singing performances of 9 points each, weighted to 10%. The weighted composite is converted to the 1-5 AP score by a cut set after each administration (not published in advance). Two subscores, also 1-5, are reported alongside it: an aural subscore (the aural multiple choice, the four dictations, and sight-singing) and a nonaural subscore (score-analysis multiple choice and Questions 5 to 7). Colleges often use the aural subscore for ear-training placement and the nonaural one for written theory.

What you bring and get

No reference sheet and no calculator: every scale, key signature, interval, chord spelling, and voice-leading rule is from memory. From May 2027 the exam is hybrid digital in Bluebook: multiple-choice questions, their scores, and all audio are on the testing device (wired headset required), free-response prompts and staves are in a paper booklet where answers are handwritten in pencil (facing pages of manuscript paper are for scratch work), and sight-singing is recorded through the device's microphone. Aural questions always supply at least one starting pitch, so only relative pitch is needed. Transposing-instrument parts state the transposition in the question; students need not memorize any instrument's transposition.
