1. The Elements of Music | 音乐要素
The seven elements of music are the basic building blocks that describe what we hear in any piece. They are pitch, duration, dynamics, tempo, timbre, texture and structure.
音乐的七大要素是描述我们在任何作品中所听到内容的基本组成部分。它们是音高、时值、力度、速度、音色、织体和结构。
Pitch refers to how high or low a note sounds. Melody uses pitch to create memorable lines, while harmony combines different pitches at the same time.
音高指的是音符的高低。旋律利用音高创造难忘的线条，而和声则同时结合不同的音高。
Duration deals with how long or short notes and rests are. Rhythm is the pattern of long and short sounds, while beat is the steady pulse you feel.
时值涉及音符与休止符的长短。节奏是长短音的组合模式，而拍子是你感受到的稳定脉动。
Dynamics describe the volume of the music, from very soft (pianissimo, pp) to very loud (fortissimo, ff) and everything in between.
力度描述音乐的强弱，从很弱 (pp) 到很强 (ff) 以及之间的各种层次。
Tempo is the speed of the music. Common tempo markings include Largo (slow), Andante (walking pace), Allegro (fast), and Presto (very fast).
速度是音乐的快慢。常见的速度术语包括 Largo（广板，缓慢）、Andante（行板，步行速度）、Allegro（快板）和 Presto（急板，非常快）。
Timbre, or tone colour, is the unique quality of a sound that lets you tell a violin from a trumpet even when they play the same note.
音色是声音的独特品质，让你即使小提琴和小号演奏同一个音也能区分开来。
Texture refers to how many layers of sound are heard and how they relate. It can be thin (a solo) or thick (a full orchestra).
织体指的是听到的声音层次有多少以及它们之间的关系。它可以很稀薄（独奏）或很浓厚（整个管弦乐团）。
Structure is the overall plan or form of a piece of music, such as verse-chorus, binary (AB), ternary (ABA) or rondo (ABACA).
结构是一首乐曲的整体布局或曲式，如主歌-副歌、二段体 (AB)、三段体 (ABA) 或回旋曲 (ABACA)。
2. Pitch and Melody | 音高与旋律
A melody is built from steps (conjunct motion) and leaps (disjunct motion). Conjunct melodies move smoothly between adjacent notes, while disjunct melodies jump across larger intervals.
旋律由级进（连贯进行）和跳进（跳跃进行）构成。级进旋律在相邻音符间平稳移动，而跳进旋律则跨越较大的音程。
Melodies are often based on scales. The most common are major scales (bright, happy) and minor scales (sad, serious). Pentatonic scales use five notes and appear in many folk and world music traditions.
旋律通常基于音阶。最常见的是大调音阶（明亮、快乐）和小调音阶（悲伤、严肃）。五声音阶使用五个音，出现在许多民间和世界音乐传统中。
A phrase is a musical sentence, often ending with a cadence. Melodies can be decorated with ornaments like trills, turns, and grace notes to add interest.
一个乐句就像一个音乐句子，通常以终止式结束。旋律可以通过颤音、回音和倚音等装饰音来增加趣味性。
Repetition, sequence (repeating a pattern at a higher or lower pitch) and contrast are important techniques in shaping melodies.
重复、模进（在更高或更低的音高上重复一个模式）和对比是塑造旋律的重要技巧。
3. Rhythm and Metre | 节奏与节拍
Rhythm is the pattern of notes and rests of different lengths. Common note values include semibreve (4 beats), minim (2 beats), crotchet (1 beat), quaver (half a beat) and semiquaver (quarter of a beat).
节奏是不同长度音符和休止符的模式。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（半拍）和十六分音符（四分之一拍）。
A time signature appears at the start of a piece. The top number shows how many beats in a bar, and the bottom number shows which note value gets one beat. For example, 4/4 has four crotchet beats per bar; 3/4 has three; 6/8 has six quaver beats, often grouped in two sets of three.
拍号出现在乐曲开头。上方数字表示每小节有几拍，下方数字表示以哪种音符为一拍。例如，4/4 拍每小节有四个四分音符拍；3/4 拍有三个；6/8 拍有六个八分音符拍，通常组合成两组三个。
Dotted notes add half the original length again. A dotted crotchet lasts for one and a half beats. Syncopation shifts the accent to a weak beat or off-beat, creating a surprise effect often heard in pop and jazz.
附点音符增加原时值的一半。附点四分音符持续一拍半。切分音将重音转移到弱拍或拍间，制造出意外效果，流行乐和爵士乐中经常听到。
Rests are moments of silence with their own values: semibreve rest, minim rest, crotchet rest, quaver rest and semiquaver rest.
休止符是沉默的时刻，有自己的时值：全休止符、二分休止符、四分休止符、八分休止符和十六分休止符。
4. Harmony and Tonality | 和声与调性
Harmony happens when two or more notes sound together. A chord is a group of notes played simultaneously. A triad is a three-note chord built from the root, third and fifth of a scale.
和声发生在两个或更多音符同时发声时。和弦是一组同时演奏的音符。三和弦是由音阶的根音、三音和五音构建的三音和弦。
The most important chords in any key are the tonic (I), dominant (V) and subdominant (IV). Together they form the backbone of many chord progressions.
任何调中最重要的和弦是主和弦 (I)、属和弦 (V) 和下属和弦 (IV)。它们一起构成了许多和弦进行的骨干。
Cadences are chord pairs that end phrases. A perfect cadence (V-I) sounds final and complete. An imperfect cadence (I-V or IV-V) sounds unfinished. A plagal cadence (IV-I) is the 'Amen' sound, and an interrupted cadence (V-vi) surprises the listener.
终止式是结束乐句的和弦对。正格终止 (V-I) 听起来终结而完满。半终止 (I-V 或 IV-V) 听起来未完成。变格终止 (IV-I) 是“阿们”的声音，阻碍终止 (V-vi) 让听众感到意外。
Tonality refers to the key of a piece. Major keys sound bright, minor keys sound darker. Modulation is when the music changes key during a piece.
调性指一首曲子的调。大调听起来明亮，小调听起来较暗。转调是音乐在作品中途改变调性。
5. Texture and Structure | 织体与结构
Monophonic texture has a single melodic line with no accompaniment. Think of a solo singer without backing. Homophonic texture has a main melody supported by chords, the most common texture today.
单音织体只有一条旋律线，没有伴奏，比如无伴奏独唱。主调织体有一条主旋律并由和弦支撑，是今天最常见的织体。
Polyphonic texture features two or more independent melodies woven together, like a canon or fugue. Heterophonic texture occurs when two or more performers play the same melody but with slightly different versions, common in some folk traditions.
复调织体具有两条或更多独立旋律交织在一起，如卡农或赋格。支声织体发生在两个或更多演奏者演奏同一旋律但略有不同版本时，常见于某些民间传统。
Structure gives music shape. Binary form (AB) has two contrasting sections, often repeated. Ternary form (ABA) returns to the opening material. Rondo form (ABACA) keeps bringing back a main theme. Theme and variations changes a melody each time it returns. Verse-chorus form is used in countless pop songs.
结构赋予音乐形状。二段体 (AB) 有两个对比段落，通常重复。三段体 (ABA) 回到开头的素材。回旋曲 (ABACA) 不断返回一个主主题。变奏曲式每次返回时改变旋律。主歌-副歌形式用于无数流行歌曲。
6. Dynamics and Articulation | 力度与演奏法
Dynamics are shown with Italian abbreviations: pianissimo (pp) very soft, piano (p) soft, mezzo piano (mp) moderately soft, mezzo forte (mf) moderately loud, forte (f) loud, fortissimo (ff) very loud.
力度用意大利语缩写表示：pianissimo (pp) 很弱，piano (p) 弱，mezzo piano (mp) 中弱，mezzo forte (mf) 中强，forte (f) 强，fortissimo (ff) 很强。
Gradual changes include crescendo (getting louder) and diminuendo or decrescendo (getting softer). A sforzando (sfz) is a sudden strong accent.
逐渐变化包括渐强和渐弱。突强 (sfz) 是突然的重音。
Articulation describes how notes are played. Legato means smoothly connected. Staccato means short and detached, shown by a dot above or below the note. An accent (>) marks a note to be played with extra force. Tenuto (-) means hold for full value. String players also use pizzicato (plucked) and arco (bowed).
演奏法描述音符如何演奏。Legato 表示圆滑连接。Staccato 表示短促分离，音符上方或下方有一个点。重音记号 (>) 表示以额外的力度演奏。Tenuto (-) 表示保持充足时值。弦乐演奏者还使用拨奏 (pizzicato) 和弓奏 (arco)。
7. Instruments and Ensembles | 乐器与合奏形式
The orchestra is divided into four families. Strings: violin, viola, cello, double bass, harp. Woodwind: flute, oboe, clarinet, bassoon. Brass: trumpet, French horn, trombone, tuba. Percussion: timpani, snare drum, cymbals, xylophone, and many more.
管弦乐队分为四个家族。弦乐：小提琴、中提琴、大提琴、低音提琴、竖琴。木管：长笛、双簧管、单簧管、大管。铜管：小号、圆号、长号、大号。打击乐：定音鼓、小军鼓、钹、木琴等等。
A string quartet consists of two violins, one viola and one cello. A wind quintet is flute, oboe, clarinet, bassoon and French horn. A jazz band often includes a rhythm section (piano, bass, drums) plus saxophones, trumpets and trombones.
弦乐四重奏由两把小提琴、一把中提琴和一把大提琴组成。木管五重奏是长笛、双簧管、单簧管、大管和圆号。爵士乐队通常包括节奏组（钢琴、贝斯、鼓）加上萨克斯管、小号和长号。
Vocal ranges from high to low are soprano, mezzo-soprano, alto, tenor, baritone and bass. A choir can be mixed (SATB) or single-gender.
从高到低的人声范围是女高音、女中音、女低音、男高音、男中音和男低音。合唱团可以是混声（SATB）或单一性别。
8. Musical Periods and Styles | 音乐时期与风格
The Baroque period (c.1600-1750) features ornamented melodies, terraced dynamics, the harpsichord and complex polyphonic textures. Key composers: Bach, Handel, Vivaldi.
巴洛克时期（约1600-1750）具有装饰性旋律、阶梯式力度、羽管键琴和复杂的复调织体。代表作曲家：巴赫、亨德尔、维瓦尔第。
The Classical period (c.1750-1820) favours clear melodies, homophonic textures, balanced phrases and the development of the symphony orchestra. Key composers: Haydn, Mozart, early Beethoven.
古典时期（约1750-1820）偏爱清晰旋律、主调织体、平衡乐句和交响乐团的发展。代表作曲家：海顿、莫扎特、早期贝多芬。
The Romantic period (c.1820-1900) expands the orchestra, uses expressive dynamics, chromatic harmony and programme music. Key composers: Tchaikovsky, Chopin, Brahms.
浪漫时期（约1820-1900）扩展了乐队编制，运用富有表现力的力度、半音和声和标题音乐。代表作曲家：柴可夫斯基、肖邦、勃拉姆斯。
20th/21st-century music explores new sounds: Impressionism (Debussy), minimalism (Reich, Glass), jazz influences, electronic music and experimental techniques. Many styles coexist today.
20/21世纪音乐探索新声音：印象主义（德彪西）、极简主义（赖希、格拉斯）、爵士乐影响、电子音乐和实验技巧。今天多种风格并存。
9. Notation and Score Reading | 记谱法与读谱
The treble clef (also called G clef) is used for higher-pitched instruments and the right hand of keyboard music. The bass clef (F clef) is used for lower instruments and the left hand of keyboard music.
高音谱号（又称G谱号）用于较高音高的乐器和键盘音乐的右手部分。低音谱号（F谱号）用于较低乐器和键盘音乐的左手部分。
Notes are placed on lines and spaces of the staff (or stave). Ledger lines extend the staff above and below. In treble clef, the spaces spell F A C E; the lines are E G B D F (Every Good Boy Deserves Football). In bass clef, the spaces are A C E G (All Cows Eat Grass); the lines are G B D F A (Good Boys Deserve Football Always).
音符放在五线谱的线和间上。加线在上下方扩展五线谱。高音谱号中，间名是 F A C E；线名是 E G B D F。低音谱号中，间名是 A C E G；线名是 G B D F A。
Accidentals include sharps (♯) raising a note by a semitone, flats (♭) lowering by a semitone, and naturals (♮) restoring the original pitch. A key signature gathers sharps or flats at the start to set the key.
变音记号包括升号 (♯) 将一个音升高半音，降号 (♭) 降低半音，还原号 (♮) 恢复原音高。调号在开头集合升号或降号来设定调性。
Ties and slurs are curved lines. A tie joins two notes of the same pitch to sound as one longer note. A slur indicates that different notes should be played smoothly (legato). Repeat marks direct you to play a section again.
连音线和圆滑线是弧线。连音线连接两个相同音高的音符，使其作为一个更长音符发声。圆滑线表示不同音符应圆滑演奏。重复记号指示你再次演奏某段。
10. Composing and Arranging | 作曲与编曲
When composing a melody, start with a clear idea or motif. Use steps and a few well-placed leaps. Create phrases that feel like questions and answers, often ending with contrasting cadences.
创作旋律时，从一个清晰的想法或动机开始。使用级进和少量恰当的跳进。创作出像问与答的乐句，常以不同的终止式结束。
Choose a key and a time signature that suit the mood. Add a chord progression using mainly I, IV and V, with vi for a more emotional twist. Experiment with inversions to make the bass line more interesting.
选择适合情绪的调号和拍号。加入主要使用 I、IV 和 V 级的和弦进行，并用 vi 级增添情感转折。尝试转位，使低音线条更有趣。
Develop your melody through repetition, sequence, augmentation (longer note values) or diminution (shorter note values). Add a contrasting B section to create binary or ternary form.
通过重复、模进、增值（更长的音符时值）或减值（更短的音符时值）发展你的旋律。加入对比的B段来创建二段体或三段体。
Texture can be varied: accompany a melody with block chords, broken chords (arpeggios) or a countermelody. Think about articulations, dynamics and tempo changes to bring your composition to life.
织体可以有变化：用柱式和弦、分解和弦（琶音）或副旋律为旋律伴奏。考虑演奏法、力度和速度变化，让你的作品栩栩如生。
11. World Music Traditions | 世界音乐传统
African drumming often uses layered rhythms and polyrhythms played on djembes and talking drums. Call and response is a key feature, with a leader playing a pattern and the group answering.
非洲鼓乐常使用在主鼓（如非洲手鼓）和说话鼓上演奏的层次化节奏和复合节奏。呼应是一种核心特征，领奏者演奏一个模式，群体应答。
Indian classical music is based on raga (melodic framework) and tala (rhythmic cycle). Instruments include sitar, tabla and tanpura. Performances often include a slow introduction (alap) followed by a composed piece (gat).
印度古典音乐以拉格（旋律框架）和塔拉（节奏循环）为基础。乐器包括西塔琴、塔布拉鼓和坦普拉琴
