Music Transcription Instrument Identification and Timbre 2 — Questions and Answers
Question 1: Which acoustic property most distinguishes the timbre of a clarinet from a flute when both play the same pitch?
- Odd-numbered harmonics dominate the clarinet's spectrum (Correct answer)
- The clarinet produces no overtones above the fundamental
- The flute has stronger odd harmonics than the clarinet
- Both instruments share identical harmonic spectra
Correct answer: Odd-numbered harmonics dominate the clarinet's spectrum
The clarinet's cylindrical bore and single-reed mechanism emphasize odd-numbered harmonics, giving it a hollow, woody timbre distinct from the flute's breathy, even-harmonic-rich tone.
Question 2: When transcribing a brass passage, you notice the tone has a buzzing, nasal quality and no valves or slides seem to be involved. Which instrument is most likely?
- French horn with a mute
- Trombone in first position
- Trumpet with a harmon mute (Correct answer)
- Flugelhorn played open
Correct answer: Trumpet with a harmon mute
The harmon (wah-wah) mute on a trumpet produces a distinctive buzzing, nasal tone that is unmistakably different from open brass sounds.
Question 3: A string instrument produces a glassy, ethereal tone without a clear pitch center on a sustained note. Which playing technique is responsible?
- Col legno
- Sul ponticello
- Harmonics (Correct answer)
- Spiccato
Correct answer: Harmonics
Natural or artificial harmonics on string instruments produce flute-like, glassy tones by lightly touching the string at nodal points instead of fully pressing it.
Question 4: In a score, you see a treble-clef instrument written in B-flat. Which of the following is NOT a B-flat transposing instrument?
- Clarinet in B-flat
- Trumpet in B-flat
- Tenor saxophone
- Alto saxophone (Correct answer)
Correct answer: Alto saxophone
The alto saxophone transposes in E-flat, meaning its written pitch sounds a major sixth lower, not in B-flat like the clarinet, trumpet, and tenor saxophone.
Question 5: Which percussion instrument produces a definite pitch and would typically require a separate staff line per note in a transcription?
- Snare drum
- Bass drum
- Marimba (Correct answer)
- Tam-tam
Correct answer: Marimba
The marimba is a pitched mallet percussion instrument whose notes are notated on a standard five-line staff, unlike unpitched drums which use single-line or X-head notation.
Question 6: A transcriber hears a keyboard instrument with a bright, harpsichord-like attack but with sustain that fades quickly and no dynamic control via key velocity. What is the instrument?
- Electric piano (Rhodes)
- Clavichord
- Harpsichord (Correct answer)
- Spinet
Correct answer: Harpsichord
The harpsichord plucks its strings mechanically, producing a bright attack with relatively fast decay and no dynamic response to key velocity.
Question 7: When identifying a guitar versus a mandolin in a transcription by timbre, which characteristic is most reliable?
- The mandolin has a warmer, sustained tone
- The guitar produces a sharper, faster decay on each note
- The mandolin has a shorter, brighter decay due to its paired string courses (Correct answer)
- Both instruments are indistinguishable by timbre alone
Correct answer: The mandolin has a shorter, brighter decay due to its paired string courses
The mandolin's paired string courses (double strings) vibrate together producing a bright, chorused attack with a relatively short decay compared to the guitar's single strings and longer sustain.
