## FAQs

### What topics are covered in AP Music Unit 2?

AP Music Theory Unit 2 covers 13 topics built around minor scales, key signatures, melody, timbre, and texture. You'll work through natural, harmonic, and melodic minor scales, relative and parallel keys, interval size and quality, interval inversion, transposing instruments, melodic features, melodic transposition, texture types, texture devices, and rhythmic devices. Here's the full topic list:
- 2.1 Minor Scales: Natural, Harmonic, and Melodic
- 2.2 Relative Keys and Key Signatures
- 2.3 Key Relationships: Parallel, Closely Related, and Distantly Related
- 2.4 Other Scales: Chromatic, Whole-Tone, and Pentatonic
- 2.5 Interval Size and Quality
- 2.6 Interval Inversion and Compound Intervals
- 2.7 Transposing Instruments
- 2.8 Timbre
- 2.9 Melodic Features
- 2.10 Melodic Transposition
- 2.11 Texture and Texture Types
- 2.12 Texture Devices
- 2.13 Rhythmic Devices See [AP Music Theory Unit 2](/ap-music-theory/unit-2) for matched study materials.

### What's on the AP Music Theory Unit 2 progress check (MCQ and FRQ)?

The AP Music Theory Unit 2 progress check tests texture, minor scales, key signatures, and intervals across both its MCQ and FRQ parts. The MCQ section asks you to identify scale types, determine relative and parallel keys, classify interval size and quality, and recognize texture types. The FRQ section typically asks you to notate key signatures, write or identify intervals, and analyze melodic or textural features in a short excerpt. The progress check draws from all 13 topics in Unit 2, so pay close attention to interval inversion (2.6), melodic transposition (2.10), and texture devices (2.12), since those show up as both multiple-choice questions and short written tasks. Practice with aligned questions at [AP Music Theory Unit 2](/ap-music-theory/unit-2).

### How do I practice AP Music Theory Unit 2 FRQs?

AP Music Theory Unit 2 FRQs most often come from key signatures, minor scales, intervals, and melodic transposition, so those are the skills to drill first. Typical question types include notating a key signature on the staff, writing a natural or harmonic minor scale, identifying or writing a specific interval, and transposing a short melody to a new key or clef. To practice effectively, write out all three forms of minor scales (natural, harmonic, melodic) from memory, then practice notating key signatures up to four sharps and flats. For melodic transposition (topic 2.10), take a short melody and move it to a different pitch level, checking that every interval relationship stays intact. Texture and timbre questions (topics 2.11-2.12) show up less often as standalone FRQs but appear in analysis prompts, so practice labeling monophony, homophony, and polyphony in short excerpts. Find practice prompts at [AP Music Theory Unit 2](/ap-music-theory/unit-2).

### Where can I find AP Music Theory Unit 2 practice questions?

The best place to find AP Music Theory Unit 2 practice questions, including multiple-choice and practice test sets, is [AP Music Theory Unit 2](/ap-music-theory/unit-2). That page has MCQ-style questions covering minor scales, key signatures, interval size and quality, texture types, and melodic transposition, which are the core skills tested in this unit. For a full practice test experience, work through questions on each of the 13 topics in order. Focus your MCQ practice on interval identification (topics 2.5-2.6) and key relationships (topics 2.2-2.3), since those appear most frequently. For written practice, College Board's AP Classroom also has a Unit 2 progress check with both MCQ and FRQ sections.

### How should I study AP Music Theory Unit 2?

Studying AP Music Theory Unit 2 well means building skills in a specific order: start with minor scales and key signatures before moving to intervals, melody, and texture. These concepts stack on each other, so rushing ahead without locking in the earlier material makes the later topics harder. Here's a concrete plan:
1. **Minor scales first.** Write out natural, harmonic, and melodic minor scales from every starting note until it's automatic. Notice how the raised 7th (harmonic) and raised 6th and 7th (melodic) change the pattern.
2. **Key signatures next.** Use the circle of fifths to connect major keys to their relative minors. Knowing that A minor shares a key signature with C major (topic 2.2) cuts your memorization in half.
3. **Intervals daily.** Drill interval size and quality (topic 2.5) and interval inversion (topic 2.6) with short daily quizzes. Intervals are the building block for everything in Units 3 and beyond.
4. **Melodic transposition.** Practice moving short melodies to new keys or clefs (topic 2.10). Check that every interval between notes stays the same after transposing.
5. **Texture and timbre last.** Learn to label monophony, homophony, polyphony, and heterophony (topic 2.11) by listening to short excerpts, then identify texture devices like imitation and ostinato (topic 2.12).
