When a bell is ringing in the first place of a change it is said to be leading. It is not following a bell in the same way as the other bells are and striking it will require practice.
The gaps between the bells should all sound even except for the handstroke lead. When ringing, the backstroke change follows on immediately after the handstroke change. However before the treble leads again at handstroke there is a gap or space of one blow. This is known as the handstroke gap or lead.
This short video on the right demonstrates and discusses the various skills required to ring rounds successfully.
The bell that is leading cannot look at and follow the bell in front of it in the change. Instead it must lead by following the last rope to come down on the opposite stroke. When leading at handstroke the bell follows the backstroke of the last rope down and when leading at backstroke the bell follows the handstroke of the last rope down. To start with your teacher will usually ensure that this is the tenor.
You can learn about leading from watching and listening to the treble in rounds:
You can also try ringing hand bells or clapping the rhythm. A word or an action may give you the idea of the one beat pause. Here the word sniff is used!
