Total Exam Length and Structure
The total exam structure AP Music Theory candidates face spans approximately 2 hours and 40 minutes, including the administrative transition to the sight-singing portion. This time is divided into two primary blocks: Section I (Multiple-Choice) and Section II (Free-Response). It is important to note that the AP Music Theory exam length is not merely a measure of endurance but a test of rapid mental switching between visual analysis and auditory processing. The first section lasts 1 hour and 20 minutes, while the written portion of the free-response section takes approximately 1 hour and 10 minutes. The final component, sight-singing, adds roughly 10 minutes of individual testing time. This structure ensures that the College Board can assess both "paper-and-pencil" theoretical knowledge and the practical application of musical literacy.
Breakdown of Section I and Section II
The AP Music Theory section breakdown is split equally in terms of scoring: Section I accounts for 45% of the total grade, and Section II accounts for the remaining 55%. Section I consists of 75 multiple-choice questions, which are further divided into aural and non-aural subsets. Section II is more complex, containing seven written free-response questions (FRQs) and two sight-singing exercises. The written FRQs include tasks such as melodic dictation, harmonic dictation, and various forms of realization or composition based on common-practice style rules. The sight-singing portion is unique because it is administered separately, often in a different room or via digital recording software, to capture the student's vocal performance of a printed melody.
Section I: Multiple-Choice Questions
Timing and Number of Questions
AP Music Theory multiple choice timing is fixed at 80 minutes for 75 questions. This section is weighted toward efficiency and accuracy. The first part of this section is driven by recorded audio prompts, meaning the pace is determined by the proctoring recording rather than the student. Once the aural portion concludes, students use the remaining time to complete the non-aural questions at their own pace. This transition is a frequent point of stress for candidates; however, the non-aural section typically allows for about one minute per question, which is sufficient for students who have mastered secondary dominants and phrase structure analysis. Scoring is based solely on the number of correct answers, with no penalty for incorrect guesses, making it advantageous to provide an answer for every item.
Aural Skills Multiple-Choice Questions
The aural subsection of Section I tests a student's ability to identify musical processes by ear. Questions often require the identification of intervals, scales (such as melodic minor or various modes), and chord qualities. More advanced questions involve listening to a musical excerpt and identifying harmonic progressions, rhythmic patterns, or errors in a printed score compared to the audio. A common task involves the cadence identification—distinguishing between authentic, plagal, deceptive, and half cadences in a four-part texture. Students must be able to retain melodic fragments in their short-term memory to recognize sequences or motivic transformations. This portion of the exam emphasizes the "functional" aspect of music theory, requiring the student to connect sound to formal terminology instantly.
Non-Aural (Written) Multiple-Choice Questions
The non-aural questions focus on score analysis and theoretical concepts presented visually. These questions cover a broad spectrum, from basic pitch and rhythm notation to complex structural analysis of a given score excerpt. Students are often asked to identify Roman numeral analysis symbols that best describe a specific chord in a musical passage or to recognize the use of non-harmonic tones like the appoggiatura or neighboring tone. There is also a significant focus on part-writing errors; a question might provide a four-voice texture and ask which measure violates the rule against parallel fifths or octaves. Mastery of the circle of fifths, transposition, and instrument ranges is essential here, as the exam frequently includes excerpts for transposing instruments like the Clarinet in Bb or Horn in F.
Section II: Free-Response Written Tasks
Melodic Dictation Tasks
Free-response questions 1 and 2 (FR1 and FR2) focus on melodic dictation. In these tasks, students listen to a short melody played several times and must transcribe it accurately on a staff. FR1 is typically a simple melody in a major key, while FR2 is usually in a minor key and may involve more complex chromaticism or rhythmic syncopation. The scoring for these tasks is based on a segment-by-segment rubric. For example, a 4-measure melody might be divided into eight segments, with points awarded for each segment where the pitch and rhythm are entirely correct. Even if a student loses track in the middle, they can regain points by correctly transcribing the final cadence. Focus on the tonic and dominant relationship is vital for orienting oneself during the first hearing.
Harmonic Dictation Tasks
FR3 and FR4 involve harmonic dictation, where the student must provide the Roman numeral analysis and transcribe the soprano and bass lines of a four-part chorale-style progression. This is often considered one of the most challenging parts of the free-response section AP Music Theory offers. Students hear the progression played 3 to 4 times. Success depends on identifying the outer voices first, as the bass line often dictates the harmony through its relationship to the scale degrees. Candidates must be proficient in identifying inversions—such as the six-four chord (second inversion)—and functional harmony. Points are awarded for both the correct notation of the soprano and bass pitches and the accuracy of the Roman numerals and figured bass symbols provided below the staff.
Part-Writing from Roman Numerals
In FR5, students are given a short bass line with Roman numerals and must provide the soprano, alto, and tenor voices. This task tests the student’s mastery of voice leading in the 18th-century chorale style. The primary objective is to avoid prohibited motions such as parallel fifths, hidden octaves, or crossed voices. Students must also ensure proper resolution of active tones, such as the leading tone resolving to the tonic or the seventh of a chord resolving downward. Scoring is rigorous; readers look for individual chord spelling, proper spacing between voices (not exceeding an octave between soprano/alto or alto/tenor), and the overall flow of the counterpoint. A single doubled leading tone can result in a mandatory point deduction according to the standard grading rubric.
FR6 requires the realization of a figured bass line. Unlike FR5, where the Roman numerals are provided, FR6 provides only the bass notes and the numerical figures that indicate the intervals to be placed above them. The student must determine the appropriate chords and write the upper three voices (SAT). This task assesses the ability to interpret shorthand notation common in the Baroque era. For instance, a '6' indicates a first-inversion triad, while a '4-2' indicates a third-inversion seventh chord. Students must be careful with chromatic alterations indicated by accidentals next to the figures. The logic of the realization must follow standard doubling rules—typically doubling the bass in a root position major or minor triad, unless it is a diminished chord where the third is preferred.
Composing a Bass Line
FR7 is the longest written task, requiring the student to compose a bass line for a given soprano melody and provide a full Roman numeral analysis. This task tests the student’s understanding of harmonic rhythm and phrase structure. The composed bass line must create a good counterpoint with the melody, primarily using contrary motion. Students must select chords that follow logical functional progressions (e.g., Predominant → Dominant → Tonic). The inclusion of a cadential six-four at the end of a phrase is a hallmark of a sophisticated response. Points are awarded based on the legality of the harmony, the melodic interest of the bass line, and the avoidance of prohibited parallels. This section allows for some creativity but stays strictly within the bounds of tonal harmony.
Section II: Free-Response Sight-Singing Tasks
The sight-singing portion AP candidates encounter consists of two melodies that must be performed a cappella. Each student is given 75 seconds to practice the melody silently or at a low volume. During this time, they are given the starting pitch or the tonic triad. After the practice period, the student has 30 seconds to record their performance. This is often done using digital recording software or a handheld recorder. It is important to realize that the student can sing using solfège (Do, Re, Mi), numbers (1, 2, 3), or any neutral syllable like "la." The choice of system does not affect the score, but consistency is key. If a student chooses solfège, using movable-do with a "la-based" minor is a common and effective strategy for handling the minor-key melody in the second task.
Scoring Criteria for Sight-Singing
Sight-singing is scored based on pitch and rhythm accuracy. Each melody is divided into segments for the purpose of grading. A student who maintains the correct intervallic relationships but transposes the entire melody up or down a half-step will still receive full credit, provided the internal logic of the melody remains intact. However, losing the sense of the tonic or failing to maintain a steady tempo can lead to significant point loss. The rubric also accounts for the tonicization of new keys if the melody happens to modulate, though most AP melodies remain in a single key. One common pitfall is stopping and restarting; the instructions state that the score is based on the first complete attempt or the most continuous performance if the student restarts.
Exam Day Logistics and Materials
What to Bring on Exam Day
Because the AP Music Theory exam involves both written and recorded components, students must come prepared with specific materials. Standard requirements include several sharpened No. 2 pencils for the multiple-choice bubble sheet and at least two pens with black or dark blue ink for the free-response written tasks. However, many proctors allow pencils for the music notation portion of the FRQs to facilitate neatness. A watch is helpful for monitoring AP Music Theory section breakdown timing, provided it does not have internet access or make noise. Most importantly, for the sight-singing portion, the school will provide the recording equipment, but students should be familiar with the specific software or device their testing center uses to avoid technical errors during the 30-second recording window.
Prohibited Items and Exam Room Policies
The most critical rule for the AP Music Theory exam is the absolute prohibition of musical instruments. This includes pianos, guitars, and even pitch pipes or tuning forks (unless the student has a documented disability accommodation). All pitch recognition must be internal. Electronic devices, including smartphones, smartwatches, and any device capable of recording or playback, are strictly forbidden and can lead to score cancellation. Furthermore, students are not permitted to bring their own manuscript paper; the exam booklet contains all the necessary staff lines for the dictation and composition tasks. Scratch paper is also generally not provided, as the margins of the exam booklet are intended for any rough notes or "pre-composing" of chord progressions.
How to Pace Yourself During the Exam
Time Management for Multiple-Choice
Pacing in Section I is divided into two distinct phases. The aural portion (approximately 30-40 minutes) is controlled by the recording. During this phase, students should use the pauses between playbacks to look ahead at the next question's options. Once the recording ends, the "non-aural" clock begins. With roughly 45 minutes left for about 40 questions, students must maintain a steady rhythm. If a particular question regarding a complex secondary leading-tone chord or a modulation is taking more than 90 seconds, it is wise to mark an educated guess and move on. Since there is no penalty for guessing, ensuring that every question is answered before time expires is the primary goal for this section.
Allocating Time for Each Free-Response Task
In the written FRQ section, time management is entirely up to the student. While the dictation questions (FR1–FR4) are paced by the recording, the remaining three questions (FR5–FR7) are completed in the remaining time—usually about 45 minutes. A common strategy is to allocate 10 minutes to FR5 (Part-writing from Roman numerals), 10 minutes to FR6 (Figured bass), and 20 minutes to FR7 (Bass line composition), leaving 5 minutes for a final review. During this review, students should specifically check for parallel octaves and ensure all accidentals are correctly placed. Because FR7 is weighted more heavily in the final score than the other composition tasks, it is vital not to rush through the bass line construction at the very end of the testing period.
