1. Note Values and Rests | 音符与休止符时值

Know the basic note tree for WJEC rhythmic dictation and notation questions. A semibreve lasts four crotchet beats, a minim lasts two, a crotchet lasts one, a quaver lasts half a crotchet beat, and a semiquaver lasts one quarter of a crotchet beat.

掌握 WJEC 节奏听写与记谱题中的基本音符时值。全音符等于四个四分音符，二分音符等于两个四分音符，四分音符为一拍，八分音符为半拍，十六分音符为四分之一拍。

A dot after a note adds half of its original value. A tie joins two notes of the same pitch and adds their values without re-striking the second note. Rests use the same proportional values: semibreve rest, minim rest, crotchet rest, quaver rest and semiquaver rest.

附点音符增加原时值的一半。延音线连接两个同音高的音符，将时值相加且第二个音不重新发声。休止符按相同比例划分：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。
