Time signatures with an 8 at the bottom are called compound time signatures.

What is a compound time signature. By that i mean a dotted quarter note divides into three eighth notes and three eighth notes divide into six sixteenth notes as shown below. Compound time signatures share the same bottom number so that means we re counting 8th beats instead of quarter beats like we do when there s a 4 representing a quarter note as the bottom number. Bottom number in time signature.

When it subdivides into three it is compound time. Gives the number of beats per measure. A mid score time signature usually immediately following a barline indicates a change of meter.

The top number is evenly divisible by 3 with the exception of time signatures where the top number is 3. If the number is greater than 3 and is also divisible by 3 the time signature is probably compound. Also each beat is divided into three components creating a one two three pulse.

Another way to group time signatures is into either simple or compound. Indicates the type of note that gets the beat. The most common compound time signatures are 6 8 9 8 12 8.

However 3 4 and 3 8 aren t compound time signatures because the top number is 3 they re simple time signatures. The most common compound time signatures are 6 8 9 8 and 12 8. Top number in time signature.

Compound time signatures differ from simple time signatures in that the beat is divided into three equal parts rather than two. In 6 8 we have 6 quavers in each bar but we could also have 6 quavers in a bar of 3 4 so what is the difference. In compound time signatures the beat is broken down into three part rhythms.

Three eighth notes are beamed together as are six sixteenth notes. Each beat is divided into three components. A simple time signature has a top number that s either a 2 3 or a 4.

There are various types of time signatures depending on whether the music follows regular or symmetrical beat patterns including simple e g 3 4 and 4 4 and compound e g 9 8 and 12 8. These are ones where we count quavers. The top number of the time signature is 2 3 or 4 depending on how many main beats per bar there are.

There is an easy way to remember the difference. In compound time signatures the beat occurs on a dotted note and is divisible by three. Dividing the number by 3 gives the number of beats per measure.

A compound time signature has a top number that s either a 6 9 or 12. The top number of the time signature is 6 2 beats 9 3 beats or 12 4 beats. The top number of compound time signatures is commonly 6 9 or 12 multiples of 3 and the most common time signatures you will see are 6 8 9 8 and 12 8.
