📚 Year 7 Cambridge Music: Formula & Theorem Quick Reference Handbook | 剑桥7年级音乐:公式定理速查手册

This handbook provides a concise collection of essential music theory formulas, rules and reference tables for Year 7 Cambridge Music students. Use it to quickly revise note values, scales, intervals, chords and more — all presented as easy‑to‑remember “formulas”.

本手册为剑桥7年级音乐学生整理了一份必备音乐理论公式、规则与速查表合集。内容涵盖音符时值、音阶、音程、和弦等,均以易记的“公式”形式呈现,方便快速复习。


1. Note Values and Rest Durations | 音符与休止符时值公式

A semibreve (whole note) lasts 4 beats in 4/4 time.

全音符在4/4拍中持续4拍。

A minim (half note) lasts 2 beats.

二分音符持续2拍。

A crotchet (quarter note) lasts 1 beat.

四分音符持续1拍。

A quaver (eighth note) lasts ½ beat.

八分音符持续½拍。

A semiquaver (sixteenth note) lasts ¼ beat.

十六分音符持续¼拍。

Dotted notes: a dot increases the note’s duration by half. Formula: dotted value = original value × 1.5.

附点音符:附点增加原音符时值的一半。公式:附点音符时值 = 原时值 × 1.5。

Rests have equivalent durations: semibreve rest, minim rest, crotchet rest, quaver rest and semiquaver rest.

休止符的时值与音符一一对应:全休止符、二分休止符、四分休止符、八分休止符、十六分休止符。


2. Time Signatures | 拍号公式

The top number tells how many beats are in a bar; the bottom number tells which note value gets one beat.

拍号上方数字表示每小节有几拍;下方数字表示以几分音符为一拍。

4/4 (common time, often written as C): 4 crotchet beats per bar.

4/4拍(常用拍号,常写作C):每小节4个四分音符拍。

3/4: 3 crotchet beats per bar — gives a waltz feel.

3/4拍:每小节3个四分音符拍,具有圆舞曲风格。

2/4: 2 crotchet beats per bar — typical march rhythm.

2/4拍:每小节2个四分音符拍,典型进行曲节奏。

6/8: compound duple metre, with two groups of three quavers per bar.

6/8拍:复二拍子,每小节由两组三连八分音符组成。


3. Major Scale Formula | 大调音阶公式

Every major scale follows the same pattern of whole tones (T or W) and semitones (S or H):

所有大调音阶都遵循相同的全音(T/W)与半音(S/H)模式:
