3/8 time signature example
Explanation of 3/8 time signature
In the article time signature, this is explained that:
- the top number indicates the number of time units in a measure (bar
- the bottom number determines the unit of time.
We can visually translate
That is to say that there are 3 eighth notes
But, what is not indicated in the time signature is that
- Simple meter (or simple time) is a meter where each beat in a measure can be subdivided by two.
- Compound meter (or compound time) is a meter where each beat in a measure can be subdivided by three.
A beat with 3/8 time signature can be divided by two or three, it depends on the context.
Here are the beats for a simple meter
In that case (simple meter):
- 1 eighth note
- 2 sixteenth
- 1 dotted quarter note
- and so on...
Here are the beats for a compound meter
- 1 dotted quarter note
- 3 eighth note
- 6 sixteenth
- and so on...
In the vast majority of cases, a 3/8 bar is a 1 beat compound measure, where each beat equals a dotted quarter note
