AP Music Theory is built around four skill categories that show up across every unit and every exam question. Understanding what each skill asks you to do, not just what content it covers, is the fastest way to close gaps before exam day.
Use this guide to see how the four skill categories connect, where each one appears on the exam, and what process moves each one requires.
AP Music Theory is not organized by skill category alone, but every task on the exam, whether you are labeling a cadence, writing a four-voice progression, or notating a melody you just heard, requires one of four specific skill moves. These categories cut across all eight units and appear in both Section I and Section II.
Analyze Performed Music and Analyze Notated Music look similar but use different inputs. Aural analysis starts with sound: you identify intervals, chord qualities, cadences, and form by ear. Notated analysis starts with a printed score: you apply Roman numerals, interval names, and formal labels to what you see. Mixing up the input source is one of the most common process errors on the exam.
Complete Based on Cues is the writing skill. You realize figured bass, write from Roman numerals, or harmonize a melody, all within 18th-century voice-leading norms. The cue tells you what chords to use; your job is to spell them correctly in four voices, avoid parallel fifths and octaves, resolve tendency tones, and double the right chord member. The rubric rewards correct process, not just correct notes.
Convert Between Performed and Notated Music covers melodic dictation, harmonic dictation, Roman numeral analysis from listening, sight-singing, and spotting discrepancies between a score and a recording. The direction matters: listening to notate is different from reading to sing. Both require you to apply pitch, rhythm, key, and meter conventions accurately.
Before you answer any AP Music Theory question, identify which skill category it belongs to. That tells you whether to listen, read, write, or convert, and it tells you which process steps and vocabulary to apply. A student who knows all the content but applies the wrong process will still lose points. Skill awareness is the meta-skill that ties the whole course together.
Identify pitch, rhythm, harmony, texture, and form by ear. This skill powers the aural multiple-choice section and requires you to name what you hear using precise musical vocabulary.
Realize figured bass, write from Roman numerals, or harmonize a melody in four-voice SATB style. The rubric checks voice leading, doubling, chord spelling, and tendency tone resolution.
Move music between sound and notation through melodic dictation, harmonic dictation, sight-singing, and discrepancy identification. Direction matters: listening to notate and reading to sing are separate processes.
Read a score and apply Roman numerals, interval names, nonchord tone labels, and formal designations. This is the written counterpart to aural analysis and appears in nonaural multiple-choice and free-response tasks.
This skill requires you to listen to a musical excerpt and identify its features using correct musical terms and symbols. It powers the aural multiple-choice questions in Section I, Part A and several free-response tasks. The process is: listen for the feature being tested, apply the correct label or symbol, and verify against what you hear, not what you assume.
| Feature | What you listen for | Common label |
|---|---|---|
| Melodic interval | Size and quality of the leap | e.g., M6, m3, P5 |
| Chord quality | Major/minor/diminished sound | e.g., major triad, dim7 |
| Cadence type | Harmonic motion at phrase end | PAC, IAC, HC, DC, PC |
| Texture | Number and independence of voices | Monophony, homophony, polyphony |
This is the part-writing and harmonization skill. You are given a cue, figured bass symbols, Roman numerals, or a melody, and you complete the missing voices in a four-part SATB texture following 18th-century stylistic norms. The rubric checks voice leading, chord spelling, doubling, and resolution of tendency tones.
| Cue type | What is given | What you write |
|---|---|---|
| Figured bass | Bass line with interval numbers | Soprano, alto, tenor voices |
| Roman numerals | Chord symbols with inversions | All four voices from scratch |
| Melody harmonization | Soprano line only | Alto, tenor, bass voices plus chord choices |
This skill moves music between sound and notation in both directions. Listening to notate covers melodic dictation, harmonic dictation, and Roman numeral analysis from a recording. Reading to perform covers sight-singing. Spotting discrepancies requires you to compare a score to a recording and identify where they differ.
| Direction | Task type | Key process step |
|---|---|---|
| Sound to notation | Melodic dictation | Establish key and meter first, then notate phrase by phrase |
| Sound to notation | Harmonic dictation | Identify bass motion and cadences, then fill in inner chords |
| Notation to sound | Sight-singing | Scan for key, meter, and range before singing |
| Both | Discrepancy spotting | Follow the score while listening; mark where sound and notation diverge |
This skill requires you to read a printed score and apply correct symbols and terms to describe pitch, rhythm, harmony, form, and musical design. It powers the nonaural multiple-choice questions in Section I, Part B and several free-response tasks. The process is: read the notation carefully, apply the correct analytical label, and verify against the score, not your ear.
| Analysis target | What to look for in the score | Label applied |
|---|---|---|
| Chord identity | Root, quality, bass note | Roman numeral with inversion symbol |
| Nonchord tone | Position relative to chord tones, resolution | PT, NT, SUS, APP, ET, PED |
| Cadence | Final two chords of a phrase | PAC, IAC, HC, DC, PC |
| Form | Phrase lengths, cadence pattern, repetition | Binary, ternary, rounded binary |
Students sometimes describe what a chord sounds like when the question shows a score, or try to read notation when the task is purely aural. Each skill category has a specific input. Read the question stem to confirm whether you are working from sound or from a score.
Parallel fifths and octaves are easy to miss when you are focused on getting the right chord. After writing each progression, check every pair of voices (soprano-alto, soprano-tenor, soprano-bass, alto-tenor, alto-bass, tenor-bass) for parallel perfect intervals.
Students who jump straight to notating pitches often misplace notes rhythmically or spell them enharmonically incorrectly. Always write the key signature and time signature, then orient yourself to the tonic before the melody begins.
A note that sounds dissonant is not automatically a suspension. Check the approach (step or leap), the position (on or off the beat), and the resolution (step down, step up, or none) to assign the correct nonchord tone label.
A common error in Roman numeral analysis is writing the correct chord quality but the wrong inversion. Always check which chord member is in the bass and match it to the correct figured bass symbol before writing the final label.
Every question in the listening multiple-choice section tests Analyze Performed Music or Convert Between Performed and Notated Music. You will hear an excerpt and answer questions about intervals, chord qualities, cadences, texture, form, or melodic patterns. The skill is identifying features by ear and selecting the correct label.
The nonaural multiple-choice section tests Analyze Notated Music. You read a printed score and answer questions about Roman numerals, nonchord tones, intervals, cadences, and form. No audio is involved. The skill is reading notation accurately and applying correct analytical vocabulary.
The free-response section tests all four skill categories. Part-writing and harmonization tasks test Complete Based on Cues. Melodic dictation and sight-singing test Convert Between Performed and Notated Music. Score analysis questions test Analyze Notated Music. Each task type has a specific rubric, and knowing which skill category you are in tells you which process steps and vocabulary the rubric is checking.
