Free BM or BMus Bachelor of Music Counterpoint and Fugal Analysis Questions and Answers — Questions and Answers
Question 1: A fugue subject begins on the dominant note and prominently features a leap to the tonic. In the corresponding answer, the initial dominant-to-tonic leap is adjusted to be a tonic-to-subdominant leap to maintain the tonic key. What is this type of answer called?
- A Real Answer
- A Tonal Answer (Correct answer)
- An Inverted Answer
- A Sequential Answer
Correct answer: A Tonal Answer
A Tonal Answer is one in which some intervals of the subject are altered to maintain the overall tonality of the piece, especially to avoid a strong modulation to the dominant at the very beginning. A Real Answer is an exact, literal transposition of the subject to the dominant.
Question 2: Which of the following best describes the contrapuntal device known as 'stretto' in a fugue?
- The subject is presented with its rhythmic values doubled.
- The subject entries in different voices begin to overlap before the previous entry has finished. (Correct answer)
- A new melodic idea is introduced to serve as a secondary subject.
- The subject is presented upside down, with its melodic intervals inverted.
Correct answer: The subject entries in different voices begin to overlap before the previous entry has finished.
Stretto (from the Italian for 'to tighten') is the overlapping of subject entries in a fugue. This device creates a sense of increased intensity and contrapuntal density, and is often found in the developmental or final sections of a fugue.
Question 3: In a standard four-voice fugal exposition, what is the most typical pattern of key relationships for the voice entries?
- Tonic - Dominant - Subdominant - Tonic
- Tonic - Tonic - Dominant - Dominant
- Tonic - Dominant - Tonic - Dominant (Correct answer)
- Tonic - Subdominant - Dominant - Tonic
Correct answer: Tonic - Dominant - Tonic - Dominant
The standard fugal exposition alternates between the subject (S) in the tonic and the answer (A) in the dominant. For four voices, this creates the pattern S(Tonic) - A(Dominant) - S(Tonic) - A(Dominant), ensuring a clear establishment of the main key and its relationship to the dominant.
Question 4: An analyst is examining a two-voice passage. The upper voice moves from E4 to F#4, while the lower voice moves from C4 to B3. What type of contrapuntal motion is occurring between the voices?
- Contrary motion (Correct answer)
- Oblique motion
- Parallel motion
- Similar motion
Correct answer: Contrary motion
Contrary motion occurs when two voices move in opposite directions. In this example, the upper voice ascends (E to F#) while the lower voice descends (C to B), demonstrating contrary motion.
Question 5: What is the primary function of an episode within the structure of a fugue?
- To present a complete statement of the subject in the tonic key for the final time.
- To introduce entirely new thematic material unrelated to the subject.
- To halt the contrapuntal motion with a homophonic, chorale-like texture.
- To provide transitional and modulatory material between statements of the subject. (Correct answer)
Correct answer: To provide transitional and modulatory material between statements of the subject.
Episodes are sections in a fugue where a complete entry of the subject is not present. They serve as transitions, often utilizing motives or fragments from the subject or countersubject, and are frequently used to modulate from the key of one subject entry to the next.
Question 6: A composer writes two melodic lines that are musically coherent. The composer then reuses these lines later in the piece, but with the lower line transposed up an octave so it is now above the original upper line. This technique, where the lines can be vertically reordered, is known as:
- Retrograde canon
- Augmentation
- Melodic sequencing
- Invertible counterpoint (Correct answer)
Correct answer: Invertible counterpoint
Invertible counterpoint (or double counterpoint when involving two voices) is the technique of writing counterpoint so that the vertical position of the melodic lines can be exchanged. The resulting combination must still adhere to the rules of harmony and counterpoint.
A fugue subject begins on the dominant note and prominently features a leap to the tonic.
In the corresponding answer, the initial dominant-to-tonic leap is adjusted to be a tonic-to-subdominant leap to maintain the tonic key.
