Group 3: identifying three single omitted rests in either simple or compound time
Activity 1
a.
crotchet rest/quaver rest/dotted crotchet rest
b.
crotchet rest/crotchet rest/crotchet rest
c.
quaver rest/quaver rest/dotted crotchet rest
The correct answer is a.
Answer
Since the first and third beats in the first bar consist of two dotted crotchets, the two missing rests need to add up to a dotted crotchet – a crotchet rest plus a quaver rest – thereby completing the bar in 9/8. The second bar also consists of time values that total two dotted crotchets and therefore a dotted crotchet rest is needed to make up the bar.
Activity 2
a.
crotchet rest/crotchet rest/minim rest
b.
quaver rest/quaver rest/dotted minim rest
c.
quaver rest/crotchet rest/dotted minim rest
The correct answer is c.
Answer
Since the beat is a dotted crotchet in 12/8, the first beat needs a quaver rest to complete it, and the fourth beat a crotchet rest. (Notice how in the first bar the two quavers are not beamed together. Therefore the second quaver marks the beginning of the fourth beat.) A dotted minim rest, which lasts for two dotted crotchet beats, is required to complete the second bar, which already includes a dotted minim extending across the first two dotted crotchet beats in the bar.
Activity 3
a.
semiquaver rest/quaver rest/quaver rest
b.
semiquaver rest/semiquaver rest/quaver rest
c.
quaver rest/semiquaver rest/crotchet rest
The correct answer is b.
Answer
Since the first beat in the first bar begins and ends with a semiquaver, two semiquaver rests are needed to make up the first crotchet. (Remember the guideline: where rests totalling less than a beat are included, group in half-beats.) And since the first beat in the second bar begins with a quaver, a quaver rest is needed to make up the crotchet beat.
