1. Intervallic Dictation and Quality | 音程听写与性质判定
Question: An ascending interval is played: D4 to G4. Write the interval name and its quality.
问题：播放一个上行音程 D4 到 G4。写出音程名称及其性质。
Answer: The interval is a perfect fourth. It spans four diatonic steps from D to G, with G being the fourth degree of the D major scale. Both notes belong to the key, and there is no semitone alteration that would make it augmented or diminished.
答案：该音程为纯四度。从 D 到 G 跨越四个自然音级，G 是 D 大调音阶的第四级音，两者均在调内，未出现使其变成增四度或减四度的半音变化。
A common mistake is to count the half steps incorrectly. A perfect fourth contains five semitones. Singing the opening of 'Amazing Grace' can help internalise the sound.
常见错误是错误计算半音数量。纯四度包含五个半音。可借助哼唱《奇异恩典》开头旋律来强化音响记忆。
Question: Now identify a descending augmented fourth from B4 to F4.
问题：再来识别下行增四度 B4 到 F4。
Answer: A perfect fourth from B to E contains five semitones, but B to F has six semitones because F is a diminished fifth above B naturally, and when inverted descending it becomes an augmented fourth. In tonal contexts, this interval often resolves outward to a sixth.
答案：B 到 E 的纯四度含五个半音，而 B 到 F 有六个半音，因为 F 是 B 上方的减五度，下行转位后即为增四度。在调性语境中，该音程常向外解决到六度。
2. Triad Construction and Inversion | 三和弦构建与转位
Question: Given the bass note E, build a first-inversion C major triad above it. Name the chord and its figured bass.
问题：已知低音为 E，在其上方构建 C 大调第一转位三和弦。写出和弦标记及数字低音。
Answer: In a C major triad (C–E–G), first inversion places E in the bass. The notes are E, G, C. Figured bass is 6/3, often abbreviated as 6. The chord function in C major is I⁶.
答案：C 大调三和弦 C–E–G 的第一转位将 E 置于低音。构成音为 E、G、C。数字低音为 6/3，常简写为 6。在 C 大调中和弦标记为 I⁶。
Extension: Build a second-inversion dominant seventh in G major. The bass note is D. Notes are D, F♯, G, B. The figured bass is 4/3, resolving regularly to a root-position tonic.
拓展：构建 G 大调属七和弦的第二转位。低音是 D，上方音为 F♯、G、B。数字低音标记为 4/3，常规解决到原位主和弦。
3. Cadence Identification in Four-Part Harmony | 四部和声终止式识别
Question: Listen to a four-bar phrase ending with chords IV–I in the key of F major. Identify the cadence and comment on its effect.
问题：聆听一个四小节乐句，终止处的和弦进行为 F 大调的 IV–I。识别终止式并评论其效果。
Answer: The cadence IV–I is a plagal cadence, often called the 'Amen' cadence. It sounds less conclusive than a perfect cadence (V–I) and creates a gentle, devotional close. In this phrase, the subdominant harmony softens the final resolution.
答案：IV–I 进行的终止式为变格终止，常被称为“阿们”终止。其收束感不如正格终止 V–I 那般强烈，营造出温和、虔敬的结束感。在此乐句中，下属和弦柔化了最后的解决。
Distractor: A progression ending with V–vi is a deceptive cadence. The ear expects I but is diverted to the submediant, creating a momentary surprise.
易混点：以 V–vi 结束的进行是阻碍终止。听觉期待进入主和弦，却被引入下中音和弦，造成瞬间的意外感。
4. Figured Bass Realisation and Voice Leading | 数字低音实现与声部进行
Question: Realise the following figured bass in four voices: bass note C with figures 6/4 5/3, key of G major.
问题：用四声部实现以下数字低音：低音为 C，数字标记为 6/4 5/3，采用 G 大调调性。
Answer: The 6/4 chord on C is the second inversion of the tonic (I⁶⁴). In G major, that chord contains G, C (bass), E. The following 5/3 chord on C is a root-position subdominant (IV) with notes C, E, A. Voice leading must be smooth: retain common tones where possible and move the remaining voices stepwise to avoid parallels.
答案：以 C 为低音的 6/4 和弦是主和弦的第二转位 I⁶⁴，在 G 大调中构成音为 G、C（低音）、E。随后的 5/3 和弦是原位下属和弦 IV，音有 C、E、A。声部进行需平稳：尽量保持共同音，其余声部级进以避免平行五八度。
The soprano could move E–E (held), alto G–A, tenor C–C. This produces an idiomatic Plagal progression often used at cadential points.
女高音可处理为 E–E（保持），女中音 G–A，男高音 C–C。这种进行构成典型的变格终止式用法，常见于终止处。
5. Melodic Dictation Error Detection | 旋律听写错误辨析
Question: The printed score shows the first four bars of Mozart’s Eine kleine Nachtmusik in G major. However, when played, the second bar has B4–D5 on the score, but the audio plays B4–C5. Identify the error and its impact.
问题：乐谱显示莫扎特《G大调弦乐小夜曲》前四小节。演奏时，第二小节乐谱记写为 B4–D5，但音频实际演奏 B4–C5。找出错误并说明其影响。
Answer: The written B4–D5 outlines the dominant seventh chord implied in the broken-chord figure, while the audio plays B4–C5, creating a major second clash. This error destroys the harmonic clarity of the dominant function and introduces an unprepared dissonance. In the style of the Classical period, such unprepared dissonance would be atypical.
答案：记谱的 B4–D5 勾勒出该分解和弦音型中隐含的属七和弦轮廓，而音频演奏的 B4–C5 制造了大二度的碰撞。这一错误破坏了属功能的清晰和声色彩，并引入了未经准备的刺耳不协和音。在古典主义风格中，此类未作预备的尖锐不协和绝非典型。
When correcting dictation, always check the implied harmony. If a note does not fit the chord outline or creates an unresolved dissonance, it is likely an error.
订正听写时，务必核查隐含和声。若某音与和弦轮廓不符或形成未解决的不协和音，则极可能为错误。
6. Unprepared Listening: Baroque Concerto Texture | 盲听分析：巴洛克协奏曲织体
Question: An excerpt from a Vivaldi concerto for two violins is played. Describe the texture, instrumental roles and use of terraced dynamics.
问题：播放一段维瓦尔第双小提琴协奏曲。描述其织体、乐器功能及阶梯式力度的运用。
Answer: The excerpt alternates between ripieno (full orchestra) and concertino (solo group) textures, typical of the concerto grosso. The two solo violins engage in imitative dialogue, while the continuo provides harmonic support. Terraced dynamics shift abruptly between forte and piano, creating dramatic contrasts without gradual crescendo.
答案：该片段在协奏部（全奏）和主奏部（独奏小组）织体之间交替，呈现大协奏曲的典型特征。两把独奏小提琴进行模仿性对话，通奏低音提供和声支撑。阶梯式力度在强奏与弱奏间突然切换，不采用渐强渐弱，营造出戏剧性对比。
The ritornello form is evident: a recurring orchestral theme punctuates the solo episodes, establishing a clear tonal architecture centred on D major.
返始咏叹调式的结构清晰可辨：乐队主题周期性返回，将独奏片段串联，建立起以 D 大调为中心的明确调性布局。
7. Composition: Completing a Balanced 8-Bar Phrase | 作曲：完成对称8小节乐句
Question: Given the first two bars of a melody in C major (ascending C–E–G–C followed by a dotted crotchet D–quaver C pattern), complete the phrase to form an 8-bar antecedent-consequent structure.
问题：给出 C 大调旋律的前两小节（上行 C–E–G–C，后接附点四分音符 D–八分音符 C 模式），完成乐句，形成 8 小节的问答式结构。
Answer: The first four bars (antecedent) should end with an imperfect cadence, perhaps ii–V. Bars 5–8 (consequent) should mirror the opening contour but lead to a perfect cadence V–I. Use sequences, rhythmic imitation and a well-placed appoggiatura on the penultimate bar to create expressive tension.
答案：前四小节（呼句）应以半终止结束，例如 ii–V。后四小节（应句）应模仿开头轮廓，但走向正格终止 V–I。可运用模进、节奏模仿，并在倒数第二小节巧妙添加倚音，以制造富有表情的张力。
A successful response balances repetition and contrast. The phrase should remain within a comfortable vocal range and use stepwise motion with occasional leaps of thirds and fourths.
成功答卷需平衡重复与对比。乐句应控制在舒适人声范围内，以级进为主，偶尔加入三度、四度跳进。
8. Modulation Analysis in a Sonata Excerpt | 奏鸣曲片段转调分析
Question: Analyse the key scheme of the first eight bars of a hypothetical classical piano sonata exposition in G major that moves to the dominant.
问题：分析一首假想古典钢琴奏鸣曲呈示部前八小节的调性布局，该曲从 G 大调过渡至属调。
Answer: Bars 1–4 clearly establish G major with a tonic-dominant pedal and a cadential V–I in the fourth bar. Bar 5 introduces an F♮ as a chromatic alteration, leading to a pivot chord: ii in G major becomes vi in D major. By bar 7, the music confirms D major with a strong perfect cadence. The modulation is therefore a diatonic pivot from G major to its dominant, D major.
答案：第 1–4 小节通过主属持续音和第四小节的 V–I 终止明确确立 G 大调。第 5 小节引入还原 F 作为半音变化，导向一个中介和弦：G 大调的 ii 级在 D 大调中化为 vi 级。至第 7 小节，强力的正格终止确认了 D 大调。因此，该转调是通过自然音中介和弦从 G 大调转至属调 D 大调。
The harmonic rhythm accelerates approaching the modulation, a common technique to heighten momentum before the secondary key is secured.
接近转调时和声节奏加快，这是增强动力感以稳固新调性的常见手法。
9. Set Work Context: Haydn Symphony No. 104 | 规定作品语境：海顿第104交响曲
Question: Discuss Haydn’s use of monothematicism and dramatic dynamic contrasts in the first movement of Symphony No. 104.
问题：论述海顿在第104交响曲第一乐章中对单主题手法和戏剧性力度对比的运用。
Answer: Haydn employs monothematicism in the Allegro, where the same basic theme serves as both first and second subject, but is transformed through orchestration and key. The dramatic contrasts emerge from sudden subito piano passages following vigorous tutti, exemplified in the opening eight bars. These sforzando accents and unexpected pauses create Sturm und Drang intensity.
答案：海顿在快板部分运用了单主题手法，同一个基本主题既作第一主题又作第二主题，但通过配器和调性变化等实现转变。戏剧性对比源于强奏全奏后骤然出现的突弱段落，开篇八小节即突出体现。这些突强重音与意外停顿营造出狂飙突进般的激烈效果。
This technique allows thematic economy while maintaining listener interest through continual textural and dynamic surprise.
这一技巧在实现主题经济性的同时，借助织体和力度的不断出奇以吸引听众。
10. Comparative Essay: Melodic Style in Baroque vs. Romantic | 比较论文：巴洛克与浪漫主义旋律风格
Question: Compare the melodic characteristics of a Corelli trio sonata and a Chopin nocturne.
问题：比较科雷利三重奏鸣曲与肖邦夜曲的旋律特征。
Answer: Corelli’s melodies are built from balanced, sequential phrases often derived from a single motivic cell, supported by a stable basso continuo. Ornamentation is tastefully applied but structurally restrained. In contrast, Chopin’s nocturne melody features wide-ranging arcs, chromatic inflections, and expressive rubato, underpinned by an arpeggiated accompaniment. The Baroque melody prioritises linear elegance; the Romantic melody emphasises emotional yearning and vocal-like cantabile.
答案：科雷利的旋律由对称、模进的乐句构成，常衍生自单个动机细胞，并以稳定的通奏低音衬托；装饰音运用品味典雅但在结构上有所克制。而肖邦夜曲的旋律以宽广的弧线、半音化润饰和表情性的伸缩节奏为特征，下方辅以琶音伴奏。巴洛克旋律优先线性优雅；浪漫主义旋律则强调情感渴望与如歌的声乐性。
In the essay, candidates should reference specific bars and use appropriate terminology such as 'periodic phrasing', 'appoggiatura chain', and 'bel canto' to deepen the analysis.
作答时，考生应引用具体小节，并使用“乐段结构”“倚音连锁”“美声风格”等恰当术语，深化分析层次。
