We will use several examples to illustrate these two concepts.
Beats - in each example you can hear a series of steady clicks, each one being a beat or a pulsation.
Measures - the beats or pulsations are grouped in numbers of two, three and four. A measure is such a pattern of a group of beats. It is very common to find measures having groups of two, three or four beats.
