Question 1: An analyst is examining the first movement of a Classical symphony. After the primary theme in the tonic key, a modulatory bridge leads to a new, lyrical theme in the dominant key. This second theme is then followed by a strong closing theme, also in the dominant, which solidifies the new key before a repeat sign. Which section of sonata form has the analyst just described?
- Development
- Exposition (Correct answer)
- Recapitulation
- Coda
Correct answer: Exposition
The exposition is the section of sonata form that presents the main thematic material. It typically includes a primary theme in the tonic key, a transition that modulates, and a secondary theme (or theme group) in a new key, usually the dominant, which is where this section concludes.
Question 2: In the analysis of a fugue, what is the term for a recurring melodic line that consistently accompanies the subject or answer in another voice?
- Episode
- Stretto
- Countersubject (Correct answer)
- Bridge
Correct answer: Countersubject
A countersubject is a distinct melodic line that is written to be played at the same time as the fugue's subject or answer. To be considered a true countersubject, it must recur consistently with the subject throughout the piece.
Question 3: Which of the following formal schemes best represents a seven-part sonata-rondo form?
- A-B-A-C-A-B-A (Correct answer)
- A-B-A-C-A-D-A
- A-B-A-B-A
- A-B-A-C-A
Correct answer: A-B-A-C-A-B-A
Sonata-rondo form blends the recurring refrain (A) of a rondo with the harmonic and thematic structure of sonata form. The A-B-A sections function like an exposition, the C section acts as a development, and the final A-B-A serves as a recapitulation, with the final B section now appearing in the tonic key.
Question 4: A Baroque dance movement is structured in two repeated sections: ||: A :||: B A' :||. The 'A' section begins in the tonic and ends on the dominant. The 'B A'' section explores new material before the opening theme returns to close the piece in the tonic. What is the most accurate classification for this form?
- Simple Ternary
- Continuous Ternary
- Sectional Binary
- Rounded Binary (Correct answer)
Correct answer: Rounded Binary
The form is binary because it consists of two repeated sections. It is 'rounded' because the initial thematic material ('A') returns at the end of the second section. It is also 'continuous' because the first section ends inconclusively in a new key (the dominant), requiring the second section to continue to the final tonic resolution. Rounded Binary is the most precise term.
Question 5: An eight-measure theme is constructed as follows: measures 1-2 present a basic idea, measures 3-4 repeat that idea (perhaps in sequence), and measures 5-8 develop fragments of the idea while driving toward a strong cadence. This 2+2+4 structure is best described as a:
- Parallel Period
- Contrasting Period
- Sentence (Correct answer)
- Phrase Group
Correct answer: Sentence
The sentence is a specific phrase structure, theorized by Arnold Schoenberg, defined by a presentation phrase (basic idea + repetition) followed by a continuation phrase (fragmentation, development) that leads to a cadence. The described 2+2+4 measure pattern is the archetypal model of the sentence.
Question 6: A composer takes a primary theme and later presents it with the rhythmic value of each note doubled (e.g., quarter notes become half notes, half notes become whole notes). What is this developmental technique called?
- Diminution
- Augmentation (Correct answer)
- Inversion
- Fragmentation
Correct answer: Augmentation
Augmentation is the technique of proportionally lengthening the rhythmic values of a theme or motif. It has the effect of slowing down the theme. The opposite technique, shortening rhythmic values, is called diminution.
