## Explanation of 4/2 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 like this:

That is to say that there are 4 half notes (minims ) per measure and the unit of time is the half note (a beat corresponds to one half note):

1 half note (minim ) equals 1 beat.
2 quarter notes (crotchets ) equals 1 beat.
4 eighth notes (quavers ) equals 1 beat.
and so on...
