1. The Building Blocks of Music | 音乐的基础
All music can be described using a common set of elements. Dynamics refer to the volume level – pianissimo (pp) very soft, piano (p) soft, mezzo-piano (mp) moderately soft, mezzo-forte (mf) moderately loud, forte (f) loud, fortissimo (ff) very loud. Gradual changes are indicated by crescendo (gradually louder) and diminuendo (gradually softer). A sudden accent is marked sforzando (sfz).
所有音乐都可以用一套共同的要素来描述。力度指音量大小——pianissimo (pp) 非常弱，piano (p) 弱，mezzo-piano (mp) 中弱，mezzo-forte (mf) 中强，forte (f) 强，fortissimo (ff) 非常强。渐强用 crescendo 表示，渐弱用 diminuendo 表示。突强则标记为 sforzando (sfz)。
Articulation tells us how notes are played: legato (smooth and connected), staccato (short and detached), accents (emphasised attack) and tenuto (held for full value). These markings shape phrasing and character.
奏法告诉我们如何演奏音符：legato（连奏，平滑连贯），staccato（断奏，短促分离），重音（强调音头）和 tenuto（充分保持时值）。这些记号塑造了乐句和性格。
Tempo is the speed of the beat, described with Italian terms: largo (very slow), adagio (slow), andante (walking pace), moderato (moderate), allegro (fast), vivace (lively), presto (very fast). Changes include accelerando (getting faster) and rallentando (getting slower); a return to the original speed is marked a tempo.
速度是节拍进行的快慢，常用意大利术语描述：largo（非常缓慢），adagio（缓慢），andante（行板），moderato（中板），allegro（快板），vivace（活泼的快板），presto（急板）。速度变化包括 accelerando（渐快）和 rallentando（渐慢）；回到原速标记为 a tempo。
Rhythm and metre cover note durations and the grouping of beats. Simple time signatures (2/4, 3/4, 4/4) divide each beat into two, while compound time (6/8, 9/8, 12/8) divides beats into three. Syncopation places stress on normally weak beats, and dotted rhythms create a long-short pattern. Triplets fit three notes into the time of two.
节奏与节拍涉及音符时值和节拍的分组。单拍子（2/4, 3/4, 4/4）将每拍分为二等份，复拍子（6/8, 9/8, 12/8）则将每拍分为三等份。切分音将重音放在通常的弱拍上，附点节奏产生长-短的模式。三连音在三拍的时间里均匀演奏三个音。
Melody is the tune; it may move by step (conjunct) or by leap (disjunct). A melodic phrase often ends with a cadence point. Pitch refers to how high or low a note sounds. Intervals measure the distance between pitches, from semitone to octave. Melodies can be ornamented with trills, turns, mordents and appoggiaturas.
旋律就是曲调；它可以是级进（conjunct）或跳进（disjunct）。一个旋律乐句常以终止式作为结束。音高指音符的高低。音程衡量两个音之间的高低距离，从半音到八度不等。旋律可以通过颤音、回音、波音和倚音来装饰。
Harmony is the vertical combination of notes to form chords. Tonality defines the key centre; music can be major, minor, modal, atonal or chromatic. Together they create tension and release. Texture describes the layers of sound – monophonic, homophonic, polyphonic or heterophonic. Instrumentation refers to the instruments and playing techniques used, while structure is the overall plan of a piece.
和声是音符纵向组合成的和弦。调性确立了调的中心；音乐可以是大调、小调、调式、无调性或半音体系。它们共同制造紧张与释放。织体描述声音的层次——单声部、主调、复调或支声。乐器法指所使用的乐器及其演奏技法，而曲式结构则是一首作品的整体布局。
2. Reading and Writing Music (Notation) | 音乐的读写（记谱法）
The treble clef fixes G on the second line, while the bass clef fixes F on the fourth line. Notes are placed on the five-line staff, with ledger lines for pitches above or below. The note-head’s position indicates pitch; its shape shows duration: semibreve (whole note), minim (half), crotchet (quarter), quaver (eighth) and semiquaver (sixteenth). Rests of equivalent value mark silence.
高音谱号将 G 定在第二线，低音谱号将 F 定在第四线。音符记写在五线谱上，加线用于超出谱表范围的音高。符头的位置表示音高，符头的形状表示时值：全音符（semibreve）、二分音符（minim）、四分音符（crotchet）、八分音符（quaver）和十六分音符（semiquaver）。同等长短的休止符表示休止。
A dot after a note increases its duration by half; a tie joins two notes of the same pitch. Accidentals – sharp (♯), flat (♭) and natural (♮) – alter pitch by a semitone. Key signatures collect sharps or flats at the start of a line, defining the tonality.
音符后的附点将其时值延长一半；连线连接两个相同音高的音。临时记号——升号 (♯)、降号 (♭) 和还原号 (♮)——将音高改变一个半音。调号在谱表开头集中标出升号或降号，明确了调性。
3. Rhythm, Tempo and Metre | 节奏、速度与节拍
The beat is the regular pulse. In simple time, the upper figure of the time signature tells you how many beats per bar, while in compound time the upper figure counts the subdivisions. The lower figure gives the note-value of each beat or subdivision. Common metres include simple quadruple (4/4) and compound duple (6/8).
节拍是规律的律动。单拍子中，拍号的上方数字表示每小节的拍数；复拍子中上方数字则表示细分份数。下方数字表示每拍或每次细分所用的音符时值。常见的拍子包括单四拍 (4/4) 和复二拍 (6/8)。
Rhythmic features to listen for include syncopation, cross-rhythms (conflicting metre patterns), hemiola (shifting from 6/8 feel to 3/4 feel) and polyrhythm (two different rhythms sounded together). Anacrusis is an upbeat before the first full bar.
需要留意的节奏特征有：切分音、交叉节奏（冲突的节拍模式）、赫米奥拉（从 6/8 感转为 3/4 感）和复节奏（同时奏响两种不同节奏）。弱起小节是第一完整小节之前的上升拍。
4. Melody, Intervals and Ornamentation | 旋律、音程与装饰音
Melodies are built from movements by step (2nd) and leap (3rd or greater). The range is the distance between highest and lowest notes. Melodic devices include sequence (repeating a phrase at a different pitch), imitation (one voice copying another) and ostinato (a repeated pattern). Phrasing can be symmetrical (4- or 8-bar) or irregular.
旋律由级进（二度）和跳进（三度及以上）构成。音域是最高音与最低音之间的距离。旋律手法包括模进（在不同音高上重复乐句）、模仿（一声部复制另一声部）和固定音型（不断重复的旋律型）。乐句可以是对称的（4或8小节）或不规则的。
Intervals are named by their size and quality: perfect 4th, perfect 5th and octave; major and minor 2nd, 3rd, 6th and 7th. Augmented and diminished intervals appear in chromatic harmony. Ornamentation – trill, turn, upper mordent, lower mordent, acciaccatura and appoggiatura – adds decoration to the melody line.
音程按度数和性质命名：纯四度、纯五度和纯八度；大、小二度、三度、六度和七度。增音程与减音程出现在半音和声中。装饰音——颤音、回音、上波音、下波音、短倚音与长倚音——为旋律线条增添色彩。
5. Harmony, Chords and Cadences | 和声、和弦与终止式
A chord is two or more notes sounding together. Triads (three-note chords) are built on scale degrees; primary triads I, IV and V define the key, while secondary triads ii, iii and vi add colour. Inversions are marked with letters after the Roman numeral: Ib (first inversion – 3rd in bass), Ic (second inversion – 5th in bass). Seventh chords add a 4th note, e.g. V7.
和弦是两个或更多音同时发声。三和弦（三个音）建立在音阶各音级上；正三和弦 I、IV、V 确立了调性，副三和弦 ii、iii、vi 增添色彩。转位用罗马数字后加字母表示：Ib（第一转位，三音在低音部）、Ic（第二转位，五音在低音部）。七和弦则加上第四个音，如 V7。
Cadences close phrases. A perfect cadence (V–I) sounds complete; an imperfect cadence (I–V, ii–V, IV–V) sounds unfinished. A plagal cadence (IV–I) is the 'Amen' cadence; an interrupted cadence (V–vi) is a surprise. Half-close and deceptive effects are fundamental to tonal music.
终止式结束乐句。正格终止 (V–I) 听感圆满；变格终止 (I–V, ii–V, IV–V) 未完成。变格终止 (IV–I) 即'阿门'终止；阻碍终止 (V–vi) 出其不意。这些终止与欺骗效果是调性音乐的基础。
Harmonic rhythm is the rate at which chords change. Diatonic harmony uses chords from the key, while chromatic harmony introduces notes outside the key. Dissonance creates tension that resolves to consonance.
和声节奏是和弦变换的速率。自然音和声使用调内和弦，而半音化和声引入调外音。不协和制造紧张，解决至协和。
6. Tonality, Keys and Modulation | 调性、调与转调
Tonality centres on a tonic note. The major scale follows the pattern W‑W‑H‑W‑W‑W‑H (semitones between 3‑4 and 7‑8). The natural minor uses W‑H‑W‑W‑H‑W‑W; harmonic minor raises the 7th, creating an augmented 2nd step. Melodic minor raises 6th and 7th ascending. Modal music uses modes (e.g. Dorian, Mixolydian), while pentatonic scales (five notes) and blues scales add characteristic inflections.
调性以一个主音为核心。大调音阶遵循 全‑全‑半‑全‑全‑全‑半 的结构（半音在 3‑4 级和 7‑8 级之间）。自然小调为 全‑半‑全‑全‑半‑全‑全；和声小调升高第 7 级，产生增二度；旋律小调上行时升高第 6、7 级。调式音乐使用中古调式（如多利亚、米克索利地亚），五声音阶（五个音）和布鲁斯音阶则带来特色音调。
Modulation is a change of key. Most common is to the dominant (e.g. C major to G major) or relative major/minor (C major ↔ A minor). The pivot chord method uses a chord shared by both keys. Chromatic and abrupt modulations create dramatic effect.
转调是调的转换。最常见的是转到属调（如 C 大调转 G 大调）或关系大小调（C 大调 ↔ a 小调）。共同和弦转调手法使用两调共有的和弦。半音转调与突然转调则制造戏剧效果。
7. Texture and Instrumental Techniques | 织体与乐器技法
Monophonic texture is a single unaccompanied line; homophonic texture features a melody with chordal accompaniment (melody and accompaniment) or block chords moving together. Polyphonic texture intertwines two or more independent melodies (contrapuntal). Heterophonic texture presents varied versions of the same melody simultaneously. Antiphonal effects exchange phrases between groups.
单声部织体是一条无伴奏的单旋律；主调织体是旋律加和弦伴奏（旋律与伴奏）或块状和弦一起移动。复调织体交织两条或更多独立旋律（对位）。支声织体同时演奏同一旋律的不同变体。应答效果在两组演奏者间交替乐句。
Common instrumental techniques: strings use arco (bowed), pizzicato (plucked), tremolo, double stopping, harmonics; woodwind use flutter‑tonguing, trills; brass use glissando, mute; percussion includes tuned (timpani, xylophone) and unpitched (snare drum, cymbals). The orchestra is
