Duple - 2 beatsTriple - 3 beatsQuadruple - 4 beats

What happens in simple and compound time?

Simple time - the beat is always undotted and the beat can be divided by/into 2Compound time - the beat is always dotted and each beat is divided into 3 sub beats e.g 6/8, 9/8, 12/8

what time signature is compound triple?

9/8

what time signature is compound quadruple?

12/8

what are complex or irregular time signatures?

all time signatures that aren't duple, triple or quadruple. they can be any number of beats per bar e.g 5/4 and 5/8 (quintuple)Their beats are divided into combos of groups e.g 7/8 = 3+2+2, 4+3, 2+3+2

What time period is irregular time signature used?

in the 20th century music, contemporary and folk music

what do these symbols mean in early music time signatures?1) circle2) C3) C - with line through it

1)triple time 2) quadruple time3) duple timeC and C-with line through it- in early times were considered imperfect time

what are notes smaller than a crochet grouper in?

usually grouped together in one beat

when notes are smaller than a crochet but in 2/4, 3/4, 3/8 or 4/8, and there is a whole bar of quavers, what are they grouped in?

all the quavers in the bar are grouped together

what about semiquavers in 3/8? how are they grouped when a full bar of them is played

all the semiquavers in the bar are grouped together

In 4/4 time, how are quavers beamed?

into groups of 4, but never across the middle of the bar (beats 2 and 3)

in 4/4 what are semiquavers grouped into?

one crochet beat

what are semiquavers and quavers beamed into when in 2/2, 3/2 or 4/2

they are beamed together in groups so that they make up one minim (3/2) beat

what happens in compound time?

each beat is a dotted note, and notes are grouped to show the beat.

when should ties not be used?

within a bar if a single or dotted note can be used instead

when must a tie be used?

between the beats if one of the notes is a semiquaver, therefore notes are grouped to show the beat

when is a semibreeve rest used?

any time except 4/2, when a breeve rest is used

what is the general rule for rests?

that each beat should have its own rest. A separate rest should be used for each silent beat

how is a half bar silence at the beginning or end of the bar in quadruple time shown? what timing does this rule also apply to?

by a single rest, but a single rest is never used across beats 2 and 34/2

when should dotted crochet rests be used?

only in compound time signatures, such as 6/8, and 9/8

in compound time, when parts of the beat has rests, what is the difference between the first 2/3 of the beat and the second?

the first 2/3 may be shown by one restthe second 2/3 must be shown separately
