Which video resolution is considered the minimum professional standard for online music lessons in 2024?
Answer: 1080p (Full HD)
1080p Full HD has become the standard for professional online lessons, providing clear enough detail to observe hand positions and instrument technique.
A piano teacher wants students to clearly see both their hands on the keys. Which camera placement is most effective?
Answer: Mounted above the keyboard looking down at an angle
An overhead or angled top-down camera position gives students a clear view of both hands simultaneously on the keyboard, which is essential for technique instruction.
What is acoustic treatment primarily designed to do in a home studio used for online lessons?
Answer: Reduce echo and reverberation within the room
Acoustic treatment (foam panels, bass traps, diffusers) absorbs or scatters sound reflections inside the room, resulting in a drier, cleaner recording environment.
Which of the following best describes a dynamic range compressor in audio production?
Answer: A processor that reduces the difference between the loudest and quietest parts of audio
A compressor automatically turns down loud sounds and can turn up quiet ones, evening out the volume of a performance for a more consistent listening experience.
A violin teacher's students frequently complain about a low-frequency hum in the audio. What is the most likely cause?
Answer: Electrical interference from nearby appliances or ground loop issues
A persistent low-frequency hum is typically caused by a ground loop or electromagnetic interference from electrical devices like monitors, power adapters, or air conditioning units.
What is the recommended sample rate for recording audio intended for online streaming platforms?
Answer: 44,100 Hz
44,100 Hz (44.1 kHz) is the CD-standard sample rate and is the most universally supported rate for streaming and online audio delivery.
What does 'chroma key' (green screen) technology allow a music teacher to do during online lessons?
Answer: Replace the background behind them with a virtual image or video
Chroma keying removes a solid-colored background (usually green) and replaces it with any chosen image or video, allowing teachers to create a clean or custom virtual studio environment.
