1. The Elements of Music | 音乐元素
All music is built from a set of fundamental elements. Recognising these building blocks allows you to describe, perform, and compose with accuracy.
所有音乐都由一组基本元素构建而成。认识这些构成要素能让你准确地描述、表演和创作音乐。
Pitch refers to how high or low a note sounds. It is determined by the frequency of vibrations, with faster vibrations producing higher pitches.
音高指的是一个音听起来的高低，由振动频率决定，频率越快音高越高。
Duration is the length of time a note or rest lasts. Composers use note values and rests to control the flow of sound and silence.
时值是音符或休止符持续的时间长度。作曲家通过音符时值和休止符来控制声音与静默的流动。
Dynamics describe the loudness or softness of music. Changes in volume add expression and shape to a performance.
力度描述音乐的强弱。音量的变化为表演添加了表现力和线条起伏。
Tempo is the speed of the beat. A fast tempo can create excitement, while a slow tempo often suggests calm or solemnity.
速度是节拍进行的快慢。快速常常制造兴奋感，而慢速则往往暗示平静或庄重。
Timbre, also known as tone colour, is the unique quality of a sound that distinguishes one instrument or voice from another, even when playing the same pitch.
音色，又称音质，是区分不同乐器或人声的独特声音质感，即使它们演奏相同的音高也能分辨。
Texture describes how many layers of sound are heard at once and how they relate to each other. Common textures include monophonic, homophonic and polyphonic.
织体描述同时听到多少个声音层次以及它们之间的关系。常见的织体有单声部、主调和复调织体。
Structure gives music form and organisation. It defines how sections are ordered and repeated, guiding the listener through a piece.
结构赋予音乐形式和条理。它决定了各部分如何排列和重复，引领听众体验全曲。
2. Pitch and Notation | 音高与记谱法
Pitch is written on a stave consisting of five lines and four spaces. Notes can sit on a line or in a space, and their vertical position shows pitch.
音高写在由五条线和四个间组成的谱表上。音符可以落在线上或间中，其纵向位置表示音高。
The treble clef is used for higher-sounding instruments and voices. It wraps around the second line, which becomes the note G, giving the clef its other name: the G clef.
高音谱号用于音域较高的乐器和人声。它环绕第二线，该线音高为 G，因此高音谱号也被称为 G 谱号。
Ledger lines are short extra lines added above or below the stave to notate pitches that go beyond the five standard lines. Middle C lies on a ledger line below the treble stave.
加线是在谱表上方或下方添加的短横线，用于记录超出五条线范围的音高。中央 C 位于高音谱表下方的一条加线上。
Notes are named using the letters A to G. After G, the pattern repeats, creating different octaves of the same letter name.
音符用字母 A 到 G 命名。G 之后字母序列循环，形成相同音名、不同八度的音。
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 any previous accidental.
变音记号改变音符的音高。升号 (♯) 将音升高一个半音，降号 (♭) 降低一个半音，还原号 (♮) 取消之前的变音记号。
Semitones and tones are the smallest intervals used in Western music. A semitone is the distance from one key to its immediate neighbour on a keyboard, and a tone equals two semitones.
半音和全音是西方音乐中使用的最小音程。半音是键盘上相邻两键的距离，全音等于两个半音。
3. Rhythm and Time Signatures | 节奏与拍号
Rhythm is the pattern of sounds and silences in time. It is created by combining notes and rests of different durations.
节奏是声音与静默在时间中的组合模式，由不同时值的音符和休止符搭配而成。
The most common note values include the semibreve (4 beats), minim (2 beats), crotchet (1 beat), quaver (½ beat) and semiquaver (¼ beat). Each note length has a corresponding rest symbol.
最常见的音符时值包括全音符 (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)。每种时值都有对应的休止符。
Dotted notes add half of the original value to the note. A dotted minim lasts for 3 beats (2 + 1), and a dotted crotchet lasts for 1½ beats.
附点音符在原有音符时值基础上增加一半。附点二分音符持续 3 拍 (2+1)，附点四分音符持续 1½ 拍。
A time signature appears at the start of a piece and consists of two numbers. The top number indicates how many beats are in each bar, while the bottom number shows what type of note counts as one beat.
拍号位于乐曲开头，由两个数字组成。上方数字表示每小节有几拍，下方数字表示以何种音符为一拍。
In simple time signatures such as 2/4, 3/4 and 4/4, each beat can be divided into two equal parts. The beat is usually a crotchet and the feel is regular and strong.
在简单拍号如 2/4、3/4 和 4/4 中，每拍可以平分为两个部分。一拍通常对应一个四分音符，节律感规律而强烈。
Compound time signatures like 6/8 divide each beat into three equal parts. In 6/8, there are 6 quavers per bar, grouped into two dotted-crotchet beats.
复拍号如 6/8 中每拍平分为三部分。6/8 拍中每小节有 6 个八分音符，它们组合成两组附点四分音符的节拍。
4. Dynamics and Articulation | 力度与演奏法
Dynamics are indicated by Italian abbreviations ranging from pp (pianissimo, very soft) to ff (fortissimo, very loud). Gradual changes use words like crescendo (getting louder) and diminuendo (getting softer).
力度用意大利语缩写标示，从 pp (pianissimo, 极弱) 到 ff (fortissimo, 极强)。渐强 (crescendo) 和渐弱 (diminuendo) 表示音量的逐步变化。
Sudden dynamic contrasts, such as sfz (sforzando), accent a single note with a strong force. This creates a dramatic effect and draws the listener's attention.
突强 (sfz, sforzando) 等突然的力度对比以强力突出某个音，制造戏剧性效果并吸引听众的注意。
Articulation describes how individual notes are performed. Common markings include legato (smooth and connected), staccato (short and detached), and accents (emphasised attacks).
演奏法描述单个音符如何演奏。常见的标记有连奏 (legato, 平滑连贯)、断奏 (staccato, 短促断开) 和重音 (强调式触键)。
Slurs are curved lines grouping notes together to be played legato. They differ from ties, which join two notes of the same pitch to create a single longer duration.
连线是连接一组音符的弧线，要求连奏。它与延音线不同，延音线连接两个同音高的音符，将其合并为一个更长的时值。
Tenuto means that a note should be held for its full value, often with a slight emphasis, and is shown by a short horizontal line above or below the note head.
保持音 (tenuto) 表示音符应保持充足时值并带有轻微强调，标记为音符上方或下方的短横线。
5. Tempo and Expression | 速度与表情术语
Tempo markings are usually given in Italian at the beginning of a score. Largo means very slow and broad, adagio is slow, andante suggests a walking pace, moderato is moderate, allegro is fast and lively, and presto is very fast.
速度标记通常以意大利语列在乐谱开头。Largo 极慢而宽广，adagio 慢速，andante 如步行速度，moderato 中速，allegro 快速活泼，presto 极快。
Metronome marks provide an exact number of beats per minute. For example, ♩ = 120 means there are 120 crotchet beats per minute.
节拍器标记给出精准的每分钟拍数。例如 ♩ = 120 表示每分钟 120 个四分音符拍。
Expressive terms indicate mood and style. Dolce means sweetly, cantabile suggests a singing tone, maestoso is majestic, and con brio means with vigour.
表情术语指示情绪和风格。dolce 意为甜美，cantabile 要求如歌唱般，maestoso 庄严雄伟，con brio 意为充满活力地。
Ritardando (rit.) tells performers to gradually slow down, while accelerando (accel.) means to gradually speed up. A tempo instructs the player to return to the original speed after a change.
渐慢 (ritardando, rit.) 指示演奏者逐渐放慢，渐快 (accelerando, accel.) 则是逐渐加快。a tempo 要求速度变化后回归原速。
A fermata placed over a note or rest means it should be held longer than its written duration, at the performer's discretion. This pause adds expressive freedom.
延音记号 (fermata) 置于音符或休止符上方，表示该音或休止可自由延长，为表演增添表现自由。
6. Instrument Families | 乐器家族
The modern orchestra is divided into four families: strings, woodwind, brass and percussion. Each family produces sound in a distinct way and occupies a typical seating position on stage.
现代管弦乐队分为四个家族：弦乐、木管、铜管和打击乐。每个家族以独特方式发声，并在舞台上占据固定的座次。
String instruments include the violin, viola, cello and double bass. They produce sound by bowing, plucking (pizzicato) or striking the strings. The harp is also a member of this family.
弦乐器包括小提琴、中提琴、大提琴和低音提琴。它们通过拉弓、拨弦 (pizzicato) 或敲击琴弦发声。竖琴也属于弦乐家族。
Woodwind instruments create sound by blowing air across a mouthpiece or vibrating a reed. Flute, oboe, clarinet and bassoon are the main orchestral woodwinds; the flute does not use a reed, while the others are reed instruments.
木管乐器通过吹气经过吹口或使簧片振动发声。主要管弦木管有长笛、双簧管、单簧管和大管；长笛不用簧片，其余为簧片乐器。
Brass instruments use vibrating lips pressed against a mouthpiece. Trumpet, French horn, trombone and tuba make up the brass section. Pitch is changed by using valves, a slide, or lip tension.
铜管乐器依靠嘴唇紧贴吹嘴振动发声。小号、圆号、长号和大号组成铜管组。音高通过活塞、滑管或唇压改变。
Percussion instruments are struck, shaken or scraped. Pitched percussion includes timpani, xylophone and glockenspiel, while unpitched percussion encompasses bass drum, snare drum, cymbals and triangle.
打击乐器通过敲击、摇晃或刮擦发声。有音高的打击乐器包括定音鼓、木琴和钟琴，无音高的打击乐器有低音鼓、小军鼓、钹和三角铁。
7. Texture in Music | 音乐织体
Texture refers to the layers of sound and how they interact. Describing texture helps listeners understand the overall density and role of each musical line.
织体指声音的层次及其相互作用。描述织体有助于听众理解各声部线条的整体密度和作用。
Monophonic texture consists of a single unaccompanied melody. It is the simplest texture and can be sung or played by one or many musicians in unison.
单声部织体由单一的、无伴奏的旋律构成。这是最简单的织体，可由一人或多人齐唱或齐奏。
Homophonic texture features a prominent melody supported by chordal accompaniment. Most pop songs and hymns are homophonic, with the tune clearly on top and harmonies beneath.
主调织体以突出的旋律为主，配有和弦伴奏。大多数流行歌曲和赞美诗是主调织体，旋律清晰在上，和声在下支撑。
Polyphonic texture weaves two or more independent melodies together at the same time. Rounds and fugues are examples of polyphonic music, where each part is equally important.
复调织体同时交织两条或更多独立旋律。轮唱曲和赋格曲是复调音乐的范例，每个声部同样重要。
Melody and accompaniment is a very common texture where a solo or unison melody line is supported by a backing track or piano accompaniment. The melody stands out, while the accompaniment provides harmonic and rhythmic support.
旋律与伴奏织体十分常见，一条独奏或齐奏的旋律线由背景伴奏或钢琴伴奏支撑。旋律突出，伴奏提供和声与节奏支持。
Call and response often appears in African and gospel music. A leader sings or plays a phrase and a group responds with a contrasting phrase, creating an interactive texture.
呼唤与应答常见于非洲音乐和福音音乐。一位领唱或领奏一个乐句，群体用对比句回应，形成互动织体。
8. Musical Structures | 音乐结构
Understanding musical structure helps performers interpret a piece and helps composers shape their ideas. The structure defines the roadmap of a composition.
理解音乐结构有助于表演者诠释作品，也帮助作曲家组织乐思。结构定义了乐曲的路线图。
Binary form (AB) consists of two contrasting sections, each usually repeated. It was very common in Baroque dance suites and is often balanced and symmetrical.
二部曲式 (AB) 由两个对比的乐段组成，每段通常重复。它在巴洛克舞蹈组曲中十分常见，结构均衡对称。
Ternary form (ABA) has three sections: the first and last are the same or very similar, while the middle section contrasts. The da capo aria is a classic ternary example.
三部曲式 (ABA) 有三个乐段：首尾相同或极为相似，中段形成对比。返始咏叹调就是经典的 ABA 例子。
Rondo form (ABACA) alternates a recurring main theme with contrasting episodes. The A section returns repeatedly, creating a lively and memorable shape.
回旋曲式 (ABACA) 让反复出现的主部主题与对比插部交替。A 段多次回归，制造出生动易记的曲式轮廓。
Theme and variations begin with a clear theme, which is then altered through changes in melody, harmony, rhythm, texture or dynamics. Each variation presents the theme in a fresh way while keeping its identity recognisable.
主题与变奏以一个清晰的主题开始，随后通过旋律、和声、节奏、织体或力度的变化进行发展。每个变奏以新颖方式呈现主题，同时保持其可辨性。
Verse-chorus structure is the backbone of countless pop and rock songs. Verses tell the story with changing lyrics, while the chorus repeats the same words and music, anchoring the song with a catchy hook.
主歌–副歌结构是无数流行和摇滚歌曲的支柱。主歌用变化的歌词叙述故事，而副歌重复相同的词曲，以朗朗上口的记忆点锚定全曲。
9. Harmony and Chords | 和声与和弦
Harmony involves the simultaneous sounding of notes to create chords and chord progressions. It adds depth and emotional direction to a melody.
和声涉及多个音同时发声以构成和弦与和弦进行。它为旋律增添深度和情感走向。
A triad is a three-note chord built of two superimposed thirds. The lowest note is the root, the middle note is the third, and the top note is the fifth. Triads can be major (happy) or minor (sad).
三和弦是由两个三度音程叠加而成的三个音组成的和弦。最低音为根音，中间为三音，最高为五音。三和弦可以是大三和弦 (明亮) 或小三和弦 (黯淡)。
The primary triads in any key are built on the first (I, tonic), fourth (IV, subdominant) and fifth (V, dominant) notes of the scale. These three chords form the backbone of tonal harmony.
任何调中的正三和弦分别建立在调式音阶的一级 (I, 主)、四级 (IV, 下属) 和五级 (V, 属) 上。这三个和弦构成了调性和声的骨架。
Chord progressions are sequences of chords that create a sense of movement and expectation. In C major, I–IV–V–I means the chords C major, F major, G major and back to C major.
和弦进行是一系列和弦的排列，营造出运动感和期待感。在 C 大调中，I–IV–V–I 指 C 大调、F 大调、G 大调再回到 C 大调。
Cadences are chord progressions that end a phrase, much like punctuation in sentences. A perfect cadence (V–I) sounds finished, a plagal cadence (IV–I) is the 'Amen' finish, an imperfect cadence (I–V, etc.) sounds incomplete, and an interrupted cadence (V–vi) creates a surprise pause.
终止式是结束乐句的和弦进行，类似句子中的标点。正格终止 (V–I) 听起来完满，变格终止 (IV–I) 是“阿门”式结尾，半终止 (I–V 等) 感到未完成，阻碍终止 (V–vi) 制造意外停顿。
Pedal notes occur when a sustained or repeated note, often in the bass, persists while chords change above it. This creates tension and a sense of anticipation.
持续音是指一个音持续或重复出现，通常在低音部，而上方的和弦不断变化。这产生张力并营造期待感。
10. Musical Eras and Styles | 音乐时期与风格
Western classical music is often divided into historical eras, each with distinct stylistic features. Learning these periods helps you place a piece in context and recognise characteristic sounds.
西方古典音乐通常划分为数个历史时期，每个时期都有独特的风格特征。了解这些时期有助于你判断作品的背景并识别典型音响。
The Baroque period (c.1600–1750) features ornate melodies, terraced dynamics, and the use of harpsichord continuo. Composers such as Bach and Handel wrote highly contrapuntal music with clear rhythmic drive.
巴洛克时期 (约 1600–1750) 以精致装饰的旋律、阶梯式力度和使用羽管键琴数字低音为特征。巴赫与亨德尔等作曲家创作了高度对位且节奏驱动力强劲的音乐。
The Classical period (c.1750–1820) prized clarity, balance and elegant melody. Haydn, Mozart and early Beethoven shaped forms like sonata form, symphony and string quartet, favouring homophonic textures and structured phrasing.
古典主义时期 (约 1750–1820) 崇尚清晰、均衡与优雅的旋律。海顿、莫扎特和早期贝多芬塑造了奏鸣曲式、交响曲和弦乐四重奏等形式，偏爱主调织体与规则的分句。
The Romantic period (c.1820–1900) emphasised intense emotion, dramatic contrasts and expanded orchestras. Composers such as Tchaikovsky, Brahms and Chopin wrote expressive melodies, used rich harmonies and explored programme music that tells a story.
浪漫主义时期 (约 1820–1900) 强调强烈的情感、戏剧性对比和扩大的管弦乐队。柴可夫斯基、勃拉姆斯和肖邦等作曲家创作富有表现力的旋律，运用丰富的和声，并探索讲述故事的音乐。
Film and video game music often borrow techniques from classical orchestration and combine them with modern electronic sounds. Leitmotifs, short recurring musical ideas representing characters or emotions, are a key device credited to composers like John Williams.
电影和电子游戏音乐常借用古典管弦配器技法，并将其与现代电子音色结合。主导动机，即代表角色或情感的短小反复的乐思，是约翰·威廉姆斯等作曲家使用的关键手法。
World music traditions introduce different rhythmic patterns, tuning systems and instruments. For example, African drumming uses polyrhythms and cyclic structures, while gamelan music from Indonesia features gongs and metallophones in interlocking layers.
世界音乐传统引入了不同的节奏模式、调音体系和乐器。例如，非洲鼓乐运用复合节奏和循环结构，而印度尼西亚的甘美兰音乐以锣和金属琴的交错层叠为特色。
