Year 9 Edexcel Music builds the foundations for GCSE by introducing essential listening, composing and performing skills. This guide pulls together every core area of knowledge you need: from the basic elements of music through to reading notation, understanding harmony and identifying key features of different styles. Each section is presented in paired English and Chinese explanations so you can master terminology and concepts in both languages.
九年级 Edexcel 音乐课程为 GCSE 打下基础，向学生介绍了基本的聆听、作曲和演奏技能。本指南汇集了你需要掌握的所有核心知识领域：从音乐的基本要素到识谱，从理解和声到识别不同风格的关键特征。每个部分都以中英配对讲解的形式呈现，帮助你同时掌握双语术语与概念。
1. The Elements of Music | 音乐的基本要素
All music can be described using a set of common elements. These include pitch (the highness or lowness of a sound), duration (how long a sound or silence lasts), dynamics (the volume), tempo (the speed), timbre (the tone colour or quality of the sound), texture (how many layers of sound are heard and how they interact), structure (the overall plan or form of a piece), silence (moments of no sound) and articulation (how individual notes are played). Understanding these terms lets you analyse any piece of music systematically.
所有的音乐都可以用一组通用的要素来描述。这些要素包括音高（声音的高低）、时长（声音或休止持续的时间）、力度（音量的大小）、速度（音乐的快慢）、音色（声音的色彩或品质）、织体（听到的声音层次有多少以及它们如何相互作用）、结构（作品的整体布局或曲式）、静默（没有声音的时刻）和运音法（单个音符的演奏方式）。理解了这些术语，你就能系统地分析任何一首作品。
For Edexcel assessments, you are expected to identify and comment on these elements in both familiar and unfamiliar listening excerpts. Start by asking: 'What is happening with pitch? Is it high or low, moving by step or leap?' Then consider rhythm and metre, dynamics and texture. Practising this approach trains your ear and builds confidence.
在 Edexcel 的考核中，你需要对熟悉或不熟悉的听力选段进行这些要素的识别与评述。首先问自己："音高上发生了什么？是高还是低，是级进还是跳进？" 然后再考虑节奏与节拍、力度和织体。经常这样练习能锻炼你的听力并建立信心。
2. Pitch, Scales and Keys | 音高、音阶与调性
Pitch refers to how high or low a note sounds. Notes are named using the first seven letters of the alphabet: A, B, C, D, E, F, G. When notes are arranged in ascending or descending order, they form a scale. Two fundamental scales in Western music are the major scale and the minor scale. A major scale follows the tone–tone–semitone–tone–tone–tone–semitone pattern, while the natural minor scale uses tone–semitone–tone–tone–semitone–tone–tone.
音高指的是一个音符听起来有多高或多低。音符用字母表的前七个字母来命名：A、B、C、D、E、F、G。当音符按照上行或下行的顺序排列时，就构成了音阶。西方音乐中两种最基本的音阶是大调音阶和小调音阶。大调音阶遵循全音–全音–半音–全音–全音–全音–半音的模式，而自然小调音阶则使用全音–半音–全音–全音–半音–全音–全音的模式。
A key is a group of pitches centred around a tonic note. For example, C major uses the notes C–D–E–F–G–A–B with no sharps or flats. G major has one sharp (F♯): G–A–B–C–D–E–F♯. Key signatures at the beginning of a staff tell the performer which notes are consistently sharpened or flattened. In Year 9 you should recognise key signatures up to two sharps and two flats and be able to identify both major and relative minor keys.
调性是一组围绕主音的音符体系。例如，C 大调使用 C–D–E–F–G–A–B，没有升号或降号。G 大调有一个升号（F♯）：G–A–B–C–D–E–F♯。谱表开头的调号告诉演奏者哪些音要持续地升高或降低。在九年级你应该能够识别最多两个升号和两个降号的调号，并能辨别大调及其关系小调。
3. Rhythm and Metre | 节奏与节拍
Rhythm is the pattern of long and short sounds and silences in time. The basic unit is the beat – a steady pulse that you can tap your foot to. In Year 9 you need to be confident with note values: semibreve (whole note, 4 beats), minim (half note, 2 beats), crotchet (quarter note, 1 beat), quaver (eighth note, ½ beat) and semiquaver (sixteenth note, ¼ beat). Rests have the same durations and include semibreve rest, minim rest, crotchet rest, etc.
节奏是音乐在时间上有长有短的声音及静默的模式。基本单位是拍子——一种你可以用脚打拍子的稳定律动。在九年级你需要熟练掌握各音符的时值：全音符（4拍）、二分音符（2拍）、四分音符（1拍）、八分音符（½拍）和十六分音符（¼拍）。休止符拥有相同的时长，包括全休止符、二分休止符、四分休止符等。
Metre describes how beats are grouped. A time signature (or metre signature) appears at the start of a piece: the top number tells how many beats per bar, the bottom number tells what kind of beat counts as one. Simple time signatures include 2/4 (two crotchet beats per bar), 3/4 (three crotchet beats) and 4/4 (four crotchet beats). Compound time signatures like 6/8 (six quavers per bar, usually felt in two groups of three) are also introduced. Syncopation occurs when the emphasis falls on a weak beat or in between beats, creating an off‑beat effect common in jazz and pop.
节拍描述的是拍子的分组方式。拍号（或节拍号）出现在乐曲的开头：上方的数字表示每小节有多少拍，下方的数字表示以哪种音符为一拍。简单拍号包括 2/4（每小节两拍，以四分音符为一拍）、3/4（三拍）和 4/4（四拍）。复拍号如 6/8（每小节六个八分音符，通常按两组三拍来感受）也开始引入。切分音出现在重音落在弱拍或拍子之间时，造成一种织体感，这在爵士乐和流行音乐中很常见。
4. Notation and Score Reading | 记谱法与读谱
Music is written on a staff (or stave) of five lines and four spaces. A clef assigns a specific pitch to a line: the treble clef (G clef) indicates that the second line from the bottom is G above middle C; the bass clef (F clef) shows that the fourth line from the bottom is F below middle C. Students are expected to read notes confidently in both clefs up to at least one ledger line above and below.
音乐写在五线四间的谱表上。谱号将特定的音高分配给某一条线：高音谱号（G 谱号）表示从下往上第二线是中央 C 上方的 G；低音谱号（F 谱号）表示从下往上第四线是中央 C 下方的 F。学生需要能够熟练阅读两种谱表中至少上下一线的音符。
Accidentals alter the pitch of a note: a sharp (♯) raises the pitch by a semitone, a flat (♭) lowers it by a semitone, and a natural (♮) cancels a previous accidental. Other symbols include the tie (a curved line joining two notes of the same pitch, adding their lengths) and the slur (a curved line over notes of different pitches, indicating legato playing). Dynamic markings like p (piano, soft) and f (forte, loud), as well as tempo words such as Allegro (fast) and Andante (walking pace), are also essential elements of a score.
变音记号改变音符的音高：升号（♯）将音高升高半音，降号（♭）将音高降低半音，还原号（♮）取消之前的变音记号。其他符号包括延音线（连接两个相同音高音符的弧线，将它们的时值相加）和圆滑线（连接不同音高音符的弧线，表示连奏）。力度记号如 p（弱）和 f（强），以及速度术语如 Allegro（快板）和 Andante（行板），同样是乐谱的基本组成部分。
5. Harmony and Chords | 和声与和弦
A chord is two or more notes sounded together. The most fundamental chord is the triad – a three‑note chord built in thirds. A major triad consists of a root, a major third (4 semitones above root) and a perfect fifth (7 semitones). A minor triad drops the third by a semitone: root, minor third (3 semitones) and perfect fifth. For example, C major is C–E–G, and C minor is C–E♭–G.
和弦是两个或更多音符同时发声。最基本的和弦是三和弦——按三度叠置的三音和弦。大三和弦由一个根音、一个大三度（根音上方 4 个半音）和一个纯五度（7 个半音）构成。小三和弦则把三音降低半音：根音、小三度（3 个半音）和纯五度。例如，C 大三和弦是 C–E–G，C 小三和弦是 C–E♭–G。
In any key, three primary chords are especially important: chords I (the tonic), IV (the subdominant) and V (the dominant). In C major, these are C (I), F (IV) and G (V). Cadences are the punctuation of music – pairs of chords that end a phrase. A perfect cadence (V–I) sounds final and complete; a plagal cadence (IV–I) sounds like 'Amen'; an imperfect cadence (I–V or IV–V) sounds unfinished; and an interrupted cadence (V–vi) surprises the listener.
在任何调性中，三个正三和弦特别重要：和弦 I（主和弦）、IV（下属和弦）和 V（属和弦）。在 C 大调中，它们是 C（I）、F（IV）和 G（V）。终止式是音乐的"标点"——结束一个乐句的和弦对。正格终止（V–I）听起来有终止感和完整感；变格终止（IV–I）听起来像"阿们"；半终止（I–V 或 IV–V）听起来未完成；阻碍终止（V–vi）则让听众感到意外。
6. Texture and Instrumentation | 织体与乐器法
Texture describes the layers of sound in a piece and how they relate. Monophonic texture contains a single unaccompanied melodic line. Homophonic texture features a melody with chordal accompaniment, where all parts move together rhythmically. Polyphonic texture has two or more independent melodies interweaving (counterpoint). Melody with accompaniment is a common homophonic variant where chords are broken or patterned rather than block‑like. In Year 9 you should be able to identify these textures aurally and in a score.
织体描述了一首作品中声音的层次及其相互关系。单声织体包含一条无伴奏的单旋律线。主调织体是一条旋律配合和弦伴奏，所有声部在节奏上一起移动。复调织体具有两条或更多独立旋律相互交织（对位）。旋律与伴奏是常见的主调变体，其中和弦是分解或模式化的，而非块状的。在九年级你应该能够从听觉和乐谱上识别这些织体。
Instrumentation refers to the choice of instruments. The Western orchestra is divided into four families: strings (violin, viola, cello, double bass), woodwind (flute, oboe, clarinet, bassoon), brass (trumpet, French horn, trombone, tuba) and percussion (timpani, snare drum, cymbals, xylophone). Knowing each instrument's timbre and range helps you describe why a composer chose a particular sound. Keyboards like the piano and organ also appear, as do electronic instruments and voices (soprano, alto, tenor, bass).
乐器法指乐器的选用。西方管弦乐队分为四个乐器组：弦乐组（小提琴、中提琴、大提琴、低音提琴）、木管组（长笛、双簧管、单簧管、大管）、铜管组（小号、圆号、长号、大号）和打击乐组（定音鼓、小军鼓、钹、木琴）。了解每种乐器的音色和音域有助于你解释作曲家为何选择某种特定的声音。键盘乐器如钢琴和管风琴也会出现，此外还有电子乐器和人声（女高音、女低音、男高音、男低音）。
7. Musical Form and Structure | 曲式与结构
Structure is the overall blueprint of a composition. Common forms in Year 9 include Binary (AB), where two contrasting sections are each usually repeated; Ternary (ABA), where the opening section returns after a contrasting middle section; and Rondo (ABACA etc.), where a main theme alternates with contrasting episodes. Theme and Variations (A, A', A'', A'''...) takes a main idea and changes it each time it returns through techniques like melodic decoration, change of key or rhythmic alteration.
结构是一首作品的整体蓝图。九年级常见的曲式包括二段体（AB），两个对比段通常各自反复；三段体（ABA），开头段落在一段对比中段后回归；以及回旋曲式（ABACA 等），一个主要主题与对比的插部交替出现。主题与变奏（A，A'，A''，A'''...）采用一个主要乐思，每次再现时通过旋律装饰、调性变化或节奏改变等手法进行变化。
The 12‑bar blues is another essential structure, rooted in African‑American musical traditions. It uses a specific chord progression over 12 bars:
Bar 1-4: I – I – I – I
Bar 5-6: IV – IV
Bar 7-8: I – I
Bar 9-10: V – IV
Bar 11-12: I – I (often with a turnaround).
Recognising this pattern is crucial for performing and composing in jazz, blues and rock styles.
12 小节蓝调是另一种基本结构，植根于非裔美国人的音乐传统。它在 12 个小节中使用特定的和弦进行：
第 1-4 小节：I – I – I – I
第 5-6 小节：IV – IV
第 7-8 小节：I – I
第 9-10 小节：V – IV
第 11-12 小节：I – I（常带有回转乐句）。
识别这一模式对于演奏和创作爵士、蓝调和摇滚风格的音乐至关重要。
8. Dynamics, Tempo and Articulation | 力度、速度与演奏法
Dynamics mark changes in volume. The most common Italian terms are pp (pianissimo, very soft), p (piano, soft), mp (mezzo‑piano, moderately soft), mf (mezzo‑forte, moderately loud), f (forte, loud) and ff (fortissimo, very loud). Gradual changes include crescendo (gradually getting louder) and diminuendo or decrescendo (gradually getting softer). These markings are essential expressive tools.
力度记号表示音量的变化。最常见的意大利术语是 pp（very soft，很弱）、p（piano，弱）、mp（mezzo‑piano，中弱）、mf（mezzo‑forte，中强）、f（forte，强）和 ff（fortissimo，很强）。渐变包括 crescendo（渐强）和 diminuendo 或 decrescendo（渐弱）。这些记号是基本的表情工具。
Tempo terms describe the speed. From slow to fast, you encounter Largo (broadly, very slow), Adagio (slow), Andante (at a walking pace), Moderato (moderately), Allegro (fast, cheerful), Vivace (lively) and Presto (very fast). Terms like accelerando (gradually getting faster) and rallentando or ritardando (gradually getting slower) indicate a change in speed. Articulation tells how a note is performed: staccato (short and detached), legato (smoothly connected), accent (a stressed note) and tenuto (held for full value, slightly stressed).
速度术语描述演奏的快慢。从慢到快，你会遇到 Largo（宽广的，很慢）、Adagio（柔板）、Andante（行板，步行速度）、Moderato（中板）、Allegro（快板，欢快的）、Vivace（活泼的）和 Presto（急板）。如 accelerando（渐快）和 rallentando 或 ritardando（渐慢）之类的术语则表示速度的变化。运音法说明一个音符如何演奏：staccato（断奏，短而分离）、legato（连奏，平滑连接）、accent（重音）和 tenuto（保持音，奏足时值，稍加强调）。
9. Periods and Styles | 音乐时期与风格
Edexcel Year 9 introduces the main Western art music periods. Baroque music (c.1600–1750) features terraced dynamics, polyphonic textures, the harpsichord and composers such as Bach and Handel. The Classical period (c.1750–1820) brought clarity, balanced phrases and homophonic textures; Mozart and Haydn are key composers. Romantic music (c.1820–1900) emphasised emotion, expanded orchestras, richer harmonies and programme music; Tchaikovsky and Brahms are typical.
Edexcel 九年级介绍了主要的西方艺术音乐时期。巴洛克音乐（约 1600–1750）以阶梯式力度、复调织体、羽管键琴为特征，代表人物有巴赫与亨德尔。古典主义时期（约 1750–1820）带来了清晰性、平衡的乐句和主调织体；莫扎特与海顿是重要作曲家。浪漫主义音乐（约 1820–1900）强调情感，扩大了管弦乐队，使用了更丰富的和声和标题音乐；柴可夫斯基与勃拉姆斯是典型代表。
The 20th century saw an explosion of styles: impressionism (Debussy, whole‑tone scales), expressionism (Schoenberg, atonality), minimalism (Reich, repeated patterns) and serialism. You should also be aware of jazz (swing rhythm, improvisation, blues scale), pop and rock (verse‑chorus structure, electric guitars, drums) and film music (leitmotifs, underscoring). Recognising characteristic features of each style helps in both listening and composing tasks.
20 世纪迎来了风格的激增：印象主义（德彪西，全音音阶）、表现主义（勋伯格，无调性）、极简主义（赖希，重复模式）和序列主义。你还应了解爵士乐（摇摆节奏、即兴演奏、蓝调音阶）、流行与摇滚乐（主歌–副歌结构、电吉他、电鼓）以及电影音乐（主导动机、配乐）。认识每种风格的特征特征有助于聆听和作曲任务。
10. Listening and Appraising | 听力与鉴赏
In Edexcel listening exercises, you will hear short extracts and answer questions about the musical elements, context and style. A successful approach is to listen for the 'big picture' first – period, ensemble, structure – and then focus on details like cadences, specific instrument entries or changes in texture. Use a vocabulary checklist: pitch (conjunct/disjunct, range), rhythm (dotted rhythms, syncopation), texture (monophonic/homophonic), dynamics (crescendo, sudden changes) and tempo.
在 Edexcel 听力练习中，你会听到短小的选段并回答有关音乐要素、背景和风格的问题。一个成功的方法是先听"大画面"——时期、合奏类型、结构——然后再关注细节，如终止式、特定乐器的进入或织体的变化。使用词汇清单：音高（级进/跳进、音域）、节奏（附点节奏、切分）、织体（单声/主调）、力度（渐强、突然变化）和速度。
Practise describing a piece using full sentences. Instead of just saying 'the dynamics change', explain how they change and the effect: 'The opening is pianissimo and sparse, creating a mysterious atmosphere; a sudden crescendo at bar 9 builds tension as the drums enter.' Linking observations to expressive intent demonstrates deeper understanding and earns higher marks.
练习用完整的句子来描述乐曲。不要只说"力度变了"，而要解释它是如何变化的以及产生的效果："开头是极弱且稀疏的，营造出一种神秘的氛围；第 9 小节突然的渐强在鼓声进入时制造出紧张感。" 将观察与表现意图联系起来能展示更深的理解，从而获得更高分数。
Finally, compare different interpretations of the same work when possible. Why might one performer choose a slower tempo or a warmer timbre? This critical thinking prepares you for more advanced appraising at GCSE level.
最后，如果可能的话，比较同一作品的不同演绎。为什么一位演奏者会选择较慢的速度或更温暖的音色？这种批判性思维为你在 GCSE 阶段更高级的音乐鉴赏做好准备。
