欢迎阅读你的 Year 7 OCR 音乐复习指南。本文梳理了所有必须掌握的核心概念：从声音的构成要素到识读乐谱，从管弦乐队乐器家族到常见曲式结构。用这份指南辅助你的课堂测评，并加深你对演奏和聆听的音乐作品的理解。
1. The Elements of Music | 音乐要素
The elements of music are the basic ingredients that make up every piece of music, no matter the style. By identifying and describing these elements, you can talk about music precisely and analytically.
音乐要素是构成一切乐曲（不论风格）的基础成分。通过辨识与描述这些要素，你可以精确而有条理地谈论音乐。
The seven key elements are: pitch (how high or low a sound is), duration (the length of sounds and silences), dynamics (the volume), tempo (the speed of the beat), timbre (the unique 'tone colour' of a voice or instrument), texture (how many layers of sound are heard and how they interact), and structure (the overall plan or form of the music).
七大核心要素为：音高（声音的高低）、时值（音与休止的长短）、力度（音量）、速度（拍子的快慢）、音色（人声或乐器的独特“声音色彩”）、织体（听觉上声音层次的多少及其相互关系）和结构（音乐的整体布局或曲式）。
When you listen to any performance, try to comment on what you can hear in each of these areas. For example, 'The pitch is mainly high,' or 'The dynamics become gradually softer.' This is the foundation of all musical analysis.
聆听任何演奏时，试着对每个领域作出评论。例如“音高主要在高音区”或“力度逐渐变弱”。这是所有音乐分析的基础。
2. Rhythm and Note Values | 节奏与音符时值
Rhythm is the pattern of long and short sounds and silences that moves music forward. The steady pulse you tap your foot to is called the beat. Different note shapes represent different lengths of sound.
节奏是推动音乐前进的长短音和休止的排列模式。你用脚打拍子的稳定的律动叫做拍点。不同的音符形状表示不同的音长。
In Year 7 you need to recognise these note values and their equivalent rests. The table below shows the most common note values using the crotchet (quarter note) as the basic beat length.
在 Year 7 你需要认识这些音符时值及其对应的休止符。下表以四分音符为基本单位（一拍）列出了最常见的音符时值。
| Note Name | Symbol | Duration (in crotchet beats) | Rest |
|---|---|---|---|
| Semibreve (Whole note) | 𝅝 (open oval) | 4 | 𝄻 |
| Minim (Half note) | 𝅗𝅥 (hollow oval with stem) | 2 | 𝄼 |
| Crotchet (Quarter note) | ♩ | 1 | 𝄽 |
| Quaver (Eighth note) | ♪ | ½ | 𝄾 |
| Semiquaver (Sixteenth note) | ♬ (two flags) | ¼ | 𝅀 |
A dot added after a note increases its length by half of its original value. A dotted minim, for instance, lasts for 3 beats (2 + 1). Ties join notes of the same pitch to make a longer sound.
音符后加一个附点，它的时值就增加原时值的一半。例如附点二分音符持续 3 拍（2+1）。连线连接同音高的音符，形成更长的音。
Always practise clapping and counting note values aloud. This will improve your rhythmic accuracy and help you read new rhythms securely.
要经常练习拍手并大声数拍子。这样能提高你的节奏准确性，并让你可以自信地视读新节奏。
3. Pitch and the Stave | 音高与五线谱
Pitch is organised on a five-line grid called the staff or stave. The higher the note is placed on the stave, the higher its pitch. In Year 7 you will mostly work with the treble clef, which fixes the position of the notes.
音高用五条线的网格（五线谱）来组织。音符在五线谱上的位置越高，音高越高。Year 7 阶段主要使用高音谱号，它固定了各音的位置。
The treble clef wraps around the second line, naming that line G. From this anchor point you can name every line and space. The five lines from bottom to top spell E, G, B, D, F – remembered by phrases such as 'Every Good Boy Deserves Football'. The four spaces spell F, A, C, E – spelling the word 'FACE'.
高音谱号盘绕在第二线上，将这条线定为 G 音。从这个锚点出发，你可以说出每一条线和间的音名。五条线从下往上依次是 E, G, B, D, F——可用口诀如“Every Good Boy Deserves Football”记忆。四个间从下往上拼出 F, A, C, E，正是英文单词“FACE”。
Notes that appear just above or below the stave use short extra lines called ledger lines. Middle C sits on the first ledger line below the treble stave. Being able to quickly identify notes by sight is a key skill for reading and writing music.
出现在五线谱上方或下方的音符，会使用短小的加线（ledger lines）。中央 C 位于高音谱表下方的第一加线上。能够快速识别音符位置，是读谱与记谱的关键技能。
4. Time Signatures and Bars | 拍号与小节
Time signatures appear at the start of a piece, right after the clef and key signature. They tell you two things: how many beats are in each bar (top number) and what type of beat counts as one beat (bottom number).
拍号出现在乐曲开头，紧接在谱号和调号之后。它告诉你两件事：每个小节有几拍（上方数字），以及以什么样的音符为一拍（下方数字）。
In Year 7 you will commonly see 2/4 (two crotchet beats per bar), 3/4 (three crotchet beats) and 4/4 (four crotchet beats). The bottom number 4 always tells you that a crotchet is the beat unit. Vertical bar lines divide the music into regularly spaced bars, and a double bar line marks the end.
在 Year 7 课程中，常见拍号有 2/4（每小节两拍四分音符）、3/4（每小节三拍）和 4/4（每小节四拍）。下方数字 4 总是表示以四分音符为一拍。单小节线把音乐划分成整齐的小节，双小节线则表示乐曲结束。
When you perform, count the beats in each bar to maintain a steady tempo. Strong beats usually fall on the first beat of the bar. This creates the natural accent pattern – for example, 4/4 has a pattern of strong-weak-medium-weak.
演奏时，数好每小节内的拍子，以保持速度稳定。强拍通常落在每小节的第一拍。这样就形成了自然的强弱规律——例如 4/4 拍遵循强-弱-次强-弱的模式。
5. Dynamics and Expression | 力度与表现
Dynamics describe how quietly or loudly music is played. Italian terms are used universally. The most common dynamic markings and their abbreviations are listed below.
力度描述音乐演奏的轻重。乐谱普遍使用意大利语术语。最常见的力度标记及缩写如下。
pianissimo (pp) – very quiet; piano (p) – quiet; mezzo piano (mp) – moderately quiet; mezzo forte (mf) – moderately loud; forte (f) – loud; fortissimo (ff) – very loud. Gradual changes are shown with crescendo (cresc.) meaning gradually getting louder, and diminuendo (dim.) or decrescendo (decresc.) meaning gradually getting quieter.
pianissimo (pp) —— 极弱；piano (p) —— 弱；mezzo piano (mp) —— 中弱；mezzo forte (mf) —— 中强；forte (f) —— 强；fortissimo (ff) —— 极强。逐渐变化用 crescendo (cresc.) 表示渐强，用 diminuendo (dim.) 或 decrescendo (decresc.) 表示渐弱。
Think how dynamics affect the mood. A quiet passage might feel secretive or gentle, while a sudden forte can create surprise. Always observe dynamic markings and experiment with controlling your instrument or voice to produce a wide dynamic range.
思考力度如何影响情绪。安静的段落可能感觉神秘或柔和，而突然的强奏可能制造意外效果。一定要遵守力度标记，并尝试通过控制乐器或嗓音来展现丰富的力度层次。
6. Tempo and Mood | 速度与情绪
Tempo is the speed of the underlying beat, measured in beats per minute (BPM). Italian terms indicate both the speed and the character of the music.
速度是基础拍点的快慢，以每分钟拍数（BPM）衡量。意大利语术语同时标示了速度与音乐的性格。
Key tempo markings from slowest to fastest include: Largo (broadly, very slow), Andante (at a walking pace), Moderato (at a moderate speed), Allegro (fast, lively), Vivace (lively and brisk), and Presto (very fast). Changes in tempo within a piece are indicated by Accelerando (accel.) – gradually getting faster, and Ritardando (rit.) or Rallentando (rall.) – gradually getting slower.
从慢到快的核心速度标记包括：Largo（宽广、极慢），Andante（步行速度），Moderato（中速），Allegro（快板、活泼），Vivace（活跃轻快），以及 Presto（急板）。乐曲内部的速度变化用 Accelerando (accel.)（渐快）和 Ritardando (rit.) 或 Rallentando (rall.)（渐慢）表示。
Composers choose tempo to match the mood: a slow tempo often suits a sad or calm atmosphere, while a fast tempo conveys excitement or joy. When you listen, identify the tempo and describe how it contributes to the overall character of the piece.
作曲家选择速度来配合情绪：慢速常适用于悲伤或平静的氛围，快速则表达兴奋或欢乐。聆听时，识别速度并描述它如何塑造乐曲的整体性格。
7. Texture and Ensemble | 织体与合奏
Texture describes how many different layers of sound are combined and how they relate to each other. The three main textures studied in Year 7 are monophonic, homophonic and polyphonic.
织体描述有多少个不同的声音层次组合在一起，以及它们如何相互关联。Year 7 阶段研究的三种主要织体是单音织体、主调织体和复调织体。
Monophonic texture consists of a single, unaccompanied melody line. Everyone sings or plays exactly the same notes at the same time (unison). Homophonic texture features a prominent melody supported by chords or a harmony part that moves in the same rhythm. This is the most common texture in pop songs and hymn tunes. Polyphonic (or contrapuntal) texture weaves together two or more independent melodies of equal interest; rounds and canons are simple examples.
单音织体由单独一条无伴奏的旋律线构成。所有人同时演唱或演奏完全相同的音符（齐奏）。主调织体有一条突出的旋律，下方由和弦或节奏一致的伴奏支撑。这是流行歌曲和赞美诗中最常见的织体。复调织体（对位织体）将两条或以上同等重要的独立旋律交织在一起；轮唱和卡农是最基础的例子。
You may also hear a melody and accompaniment texture, a type of homophony where a clear tune is accompanied by broken chords, drums or bass lines. When describing texture, identify the number of parts, whether they move together and if any part stands out.
你也可能听到旋律加伴奏织体，这是主调织体的一种，由清晰的主题旋律配上分解和弦、鼓或低音线条。描述织体时，辨明声部数量、它们是否同节奏运动、以及是否有某一层次格外突出。
8. Instrument Families of the Orchestra | 管弦乐队乐器家族
The modern symphony orchestra is divided into four families, grouped by how the sound is produced. Recognising instruments by their timbre and knowing which family they belong to is a key listening skill.
现代交响乐队按发声方式分成四个家族。凭音色辨认乐器并知道它属于哪个家族，是一项核心听力技能。
| Family | How sound is made | Common instruments | Tone colour / range |
|---|---|---|---|
| Strings | Bowing, plucking or striking strings | Violin, viola, cello, double bass, harp | Warm, singing quality; wide dynamic and expressive range |
| Woodwind | Blowing air through a reed or across a hole | Flute, clarinet, oboe, bassoon | Clear, reedy or breathy; agile melodies |
| Brass | Buzzing lips into a metal mouthpiece | Trumpet, French horn, trombone, tuba | Powerful, bright; often used for fanfares and climaxes |
| Percussion | Striking, shaking or scraping | Timpani, snare drum, cymbals, xylophone, triangle | Rhythmic drive and colour; pitched and unpitched |
Percussion instruments are further divided into tuned (e.g. xylophone, glockenspiel, timpani) and untuned (e.g. triangle, snare drum, cymbals). Keyboard instruments like the piano and organ are often treated separately because they can produce both melody and harmony across a huge range.
打击乐器进一步分为有音高的（如木琴、钟琴、定音鼓）和无音高的（如三角铁、小军鼓、钹）。钢琴和管风琴等键盘乐器常单独分类，因为它们能在极宽的音域中同时呈现旋律与和声。
When you listen, try to map the instruments you hear to their families and describe how they contribute to texture and mood. Orchestral music frequently uses contrasts between families to create dramatic effects.
聆听时，尝试把听到的乐器归入相应家族，并描述它们对织体和情绪的贡献。管弦乐常利用不同乐器家族间的对比，制造戏剧性效果。
9. Structure and Form | 结构与曲式
Structure describes how a piece of music is organised into sections. Recognising the overall shape helps you follow the story the composer is telling.
结构描述一首乐曲如何组织成段落。识别整体布局有助于你领会作曲家所讲述的故事脉络。
Common forms in Year 7 include: Binary (AB) – two contrasting sections, often each repeated; Ternary (ABA) – a first section, a contrasting middle, then a return of the first section; Rondo (ABACA) – a main theme (A) that keeps coming back between contrasting episodes; Theme and Variations – a theme is stated and then altered in different ways (change of key, tempo, rhythm, instrumentation); and Verse-Chorus – the structure of countless pop songs, where verses tell the story and the chorus repeats the main idea.
Year 7 常见曲式包括：二部曲式 (AB)——两个对比段落，常各自反复；三部曲式 (ABA)——第一段，对比中段，再现第一段；回旋曲式 (ABACA)——一个主题（A）在对比插部间不断回归；主题与变奏——先陈述一个主题，再通过调性、速度、节奏、配器等方式进行变化；以及主歌-副歌——
