# Group 3: identifying three single omitted rests in either simple or compound time

## Activity 1

Which single rest is required at each of the places marked with asterisks?

a.

crotchet rest/quaver rest/dotted crotchet rest

b.

crotchet rest/crotchet rest/crotchet rest

c.

quaver rest/quaver rest/dotted crotchet rest

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

Which single rest is required at each of the places marked with asterisks?

a.

crotchet rest/crotchet rest/minim rest

b.

quaver rest/quaver rest/dotted minim rest

c.

quaver rest/crotchet rest/dotted minim rest

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

Which single rest is required at each of the places marked with asterisks?

a.

semiquaver rest/quaver rest/quaver rest

b.

semiquaver rest/semiquaver rest/quaver rest

c.

quaver rest/semiquaver rest/crotchet rest

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.
