1. What does the key signature of a piece of music indicate? → The key of the composition
2. In a standard 4/4 time signature drum pattern, which beat is the snare drum most commonly placed on? → Beats 2 and 4
3. What does a 'multiband compressor' do differently from a standard broadband compressor? → It splits the signal into frequency bands and applies independent compression to each band
4. What is a 'bus' (or 'submix') in DAW routing? → An internal signal path that collects outputs from multiple tracks for grouped processing
5. Which of the following progressions represents a standard ii-V-I turnaround in a major key? → Dm7 - G7 - Cmaj7
6. Which of the following best describes 'moral rights' as they relate to US copyright law for music? → Moral rights in the US apply only to works of visual art, not music
7. When recording a snare drum, a second microphone is often placed beneath the snare pointing upward. What does this bottom mic primarily capture? → The resonance and sizzle of the snare wires
8. What is a mechanical royalty? → Payment for reproducing music
9. When tracking a full band live in a studio, what is the primary purpose of recording 'scratch vocals'? → To provide a reference guide for the musicians without committing to a keeper take
10. Which technique is commonly used to create depth and distance for a sound in a mix? → Adding reverb and slightly reducing high-frequency content to simulate air absorption
11. What does 'normalizing' audio do? → Sets max volume to a consistent level
12. Which US Copyright Office form is used to register a claim in a musical composition? → Form PA
13. What is the primary purpose of a diffuser panel in a recording studio? → Scatter sound waves to reduce flutter echo
14. When using a large-diaphragm condenser microphone on a vocalist, where should the engineer place it to minimize plosives? → Above the mouth angled slightly downward
15. What is the primary purpose of a Controlled Composition Clause in a recording contract? → To limit the mechanical royalty rate the label pays for songs written by the artist
16. In EQ, what does a 'bell curve' (peaking filter) allow you to do? → Boost or cut a specific frequency range with an adjustable bandwidth (Q)
17. In sound design, what does 'FM synthesis' stand for? → Frequency Modulation
18. Why is acoustic treatment important in a recording studio? → To reduce ambient noise and reflections
19. What does 'allegro' indicate in a musical score? → Play quickly and lively
20. A recording shows a consistent 60 Hz hum on multiple tracks. What is the most common cause of this? → A ground loop in the analog signal chain
21. What does increasing the 'Q' (quality factor) on a parametric EQ band do? → It narrows the bandwidth, making the boost or cut more surgical and precise
22. What does 'consolidating' audio clips in a DAW accomplish? → Rendering multiple adjacent or edited clips on a track into a single continuous audio file
23. In mastering, what is the typical target integrated loudness for music distributed on Spotify? → -14 LUFS
24. What is the role of a 'bus' in a DAW session? → A routing channel that combines multiple tracks for shared processing
25. What is the term for the legal owner of a sound recording? → Master rights holder
26. A recording engineer notices a 'comb filtering' artifact in a guitar track. What most likely caused it? → Two slightly delayed versions of the same signal being combined
27. Which panning law setting compensates for the perceived volume increase when a signal is panned to center in a stereo mix? → -3 dB panning law
28. Which plugin adds spatial ambiance to sound? → Reverb
29. In mastering, what is the purpose of a True Peak limiter set to -1 dBTP? → To prevent inter-sample peaks from causing distortion after lossy encoding
30. An independent producer wants to protect a unique production technique. Which form of IP protection is most appropriate? → Trade secret, by keeping the technique confidential without public disclosure
