Music Transcription Timbre and Instrumentation 3 — Questions and Answers
Question 1: Which acoustic property most directly determines the perceived pitch of a sound?
- Amplitude
- Fundamental frequency (Correct answer)
- Spectral envelope
- Attack time
Correct answer: Fundamental frequency
Fundamental frequency is the lowest frequency component of a sound and is the primary determinant of perceived pitch.
Question 2: When transcribing a recording, you hear a sustained note with a slow, regular pitch oscillation. What should you notate?
- Trill
- Vibrato (Correct answer)
- Tremolo
- Glissando
Correct answer: Vibrato
Vibrato is a periodic fluctuation in pitch, and is notated with 'vib.' or a wavy line above the note.
Question 3: Which instrument produces its sound by air passing over a sharp edge (edge-tone mechanism)?
- Clarinet
- Oboe
- Flute (Correct answer)
- Saxophone
Correct answer: Flute
The flute uses an edge-tone mechanism where the player directs air across the embouchure hole, unlike reeds used in clarinet, oboe, and saxophone.
Question 4: When transcribing a harpsichord piece for piano, the transcriber must account for which key timbral difference?
- Harpsichord has a longer sustain than piano
- Harpsichord volume cannot be controlled by key velocity (Correct answer)
- Harpsichord has a warmer tone in the low register
- Harpsichord lacks upper harmonics
Correct answer: Harpsichord volume cannot be controlled by key velocity
Harpsichord strings are plucked mechanically regardless of key pressure, so dynamic nuance from key velocity is not possible as it is on the piano.
Question 5: In a woodwind quintet transcription, which instrument is NOT part of the standard ensemble?
- Oboe
- Clarinet
- Saxophone (Correct answer)
- French horn
Correct answer: Saxophone
The standard woodwind quintet consists of flute, oboe, clarinet, bassoon, and French horn—saxophone is not included.
Question 6: A transcriber wants to notate the effect of bowing a string instrument behind the bridge. What timbre should they expect?
- Warm, resonant tone
- Scratchy, high-pitched noise (Correct answer)
- Clear bell-like harmonics
- Deep, resonant bass
Correct answer: Scratchy, high-pitched noise
Bowing behind the bridge (sul ponticello extreme) produces a scratchy, high-pitched, and somewhat unpitched noise effect.
Question 7: When transcribing an organ piece for piano, which characteristic of the organ CANNOT be replicated on piano?
- Ability to sustain notes indefinitely (Correct answer)
- Ability to play chords
- Dynamic contrast via touch
- Playing in multiple octaves simultaneously
Correct answer: Ability to sustain notes indefinitely
The organ can sustain notes for as long as a key is held, while the piano's sound decays after the key is struck.
