Online Music Lessons Virtual Performance Preparation 2 — Questions and Answers
Question 1: What is the primary purpose of a 'virtual green room' before an online performance?
- A dedicated Zoom room for performers to warm up and connect before going live (Correct answer)
- A software filter that makes your background appear green
- A playlist of calming music streamed before the event starts
- A checklist app that verifies your internet connection
Correct answer: A dedicated Zoom room for performers to warm up and connect before going live
A virtual green room replicates the backstage waiting area, giving performers a space to warm up, coordinate, and manage nerves before the live stream begins.
Question 2: Which microphone polar pattern is generally best for recording a solo acoustic guitar in a home studio with some room noise?
- Omnidirectional
- Cardioid (Correct answer)
- Figure-8 (bidirectional)
- Hypercardioid
Correct answer: Cardioid
A cardioid pattern picks up sound primarily from the front and rejects sound from the rear, minimizing background room noise during a solo recording.
Question 3: During a livestreamed recital, you notice a 2-second delay between your playing and what the audience hears. What is the most likely cause?
- Your instrument is out of tune
- High streaming latency caused by network or encoder settings (Correct answer)
- The audience's video player has lip-sync issues unrelated to audio
- Your audio interface sample rate is set too high
Correct answer: High streaming latency caused by network or encoder settings
Streaming latency—caused by buffering in the encoder, CDN, or viewer's player—is the most common reason for delayed audio during a live performance stream.
Question 4: What does 'bit depth' affect in a digital audio recording for a virtual performance?
- The tempo accuracy of recorded MIDI notes
- The dynamic range and noise floor of the audio (Correct answer)
- The number of simultaneous tracks you can record
- The video resolution of your stream
Correct answer: The dynamic range and noise floor of the audio
Bit depth determines how many amplitude values can be represented per sample, directly affecting dynamic range and the noise floor of the recording.
Question 5: A pianist preparing for a virtual masterclass wants to show both their hands and the keyboard clearly. Which camera angle is most effective?
- A front-facing webcam at eye level
- An overhead camera angled down at the keys (Correct answer)
- A side-angle camera at bench height showing the full profile
- A camera mounted inside the piano lid
Correct answer: An overhead camera angled down at the keys
An overhead or slightly angled top-down camera provides a clear view of both hands and the full keyboard, which is essential for pedagogical masterclass viewing.
Question 6: What is 'encoder bitrate' and why does it matter for a virtual musical performance?
- The speed at which your MIDI controller sends note data
- The amount of data per second used to compress your audio/video stream (Correct answer)
- The number of simultaneous viewers your stream can support
- The refresh rate of your streaming software interface
Correct answer: The amount of data per second used to compress your audio/video stream
Encoder bitrate controls how much data is used per second to represent your audio and video; too low causes compression artifacts that muddy the sound and blur the image.
Question 7: When scheduling a virtual ensemble performance across multiple time zones, which format should you use when communicating the performance time to all participants?
- Local time of the performer with the most participants
- UTC (Coordinated Universal Time) with each participant's local conversion (Correct answer)
- Eastern Standard Time only, since most US participants use it
- Whichever time zone the streaming platform is based in
Correct answer: UTC (Coordinated Universal Time) with each participant's local conversion
Sharing time in UTC alongside local conversions eliminates confusion and ensures every performer across different time zones arrives at the correct moment.
