Which lighting setup is often recommended as a starting point for good video quality in online music lessons?
Answer: Three-point lighting (key, fill, and back light)
Three-point lighting uses a key light for primary illumination, a fill light to soften shadows, and a back light to separate the subject from the background, creating a professional look.
A student's audio sounds 'tinny' and lacks warmth during online lessons. Which EQ adjustment would most likely improve this?
Answer: Boost frequencies in the 100–300 Hz range
The 100–300 Hz range contains the warmth and body of most instruments and voices; boosting this region adds fullness to a thin-sounding recording.
What is a USB audio interface used for in an online music lesson setup?
Answer: Converting analog microphone or instrument signals to digital audio for the computer
A USB audio interface converts analog signals from microphones or instruments into digital audio data that the computer can process, providing far better quality than a built-in sound card.
Why is it important to avoid sitting directly in front of a bright window during a video lesson?
Answer: The strong backlight will silhouette the teacher, making their face difficult to see
When the primary light source is behind the subject, the camera exposes for the bright background, leaving the subject severely underexposed and appearing as a dark silhouette.
What does increasing the 'gain' on a microphone preamp do?
Answer: Amplifies the microphone's output signal before it reaches the recorder
Gain controls how much the preamp amplifies the microphone's signal; increasing it makes quiet sounds more audible, but too much gain introduces unwanted noise and distortion.
A drum teacher wants to capture the full kit clearly for online lessons. Which approach provides the best visual coverage?
Answer: A wide-angle camera placed in front of and above the kit to capture the full setup
A wide-angle camera positioned in front of and slightly above the kit provides a comprehensive view of the entire drum set, allowing students to observe full-body technique and limb coordination.
What is the main advantage of using a wired ethernet connection instead of Wi-Fi for online music lessons?
Answer: Ethernet provides lower latency and more stable bandwidth, reducing dropouts
Ethernet connections are more stable and consistent than Wi-Fi, resulting in lower ping times, fewer packet losses, and a more reliable lesson experience with less buffering.
