The tricky part now is to start
this beat at the same time as first beat of the bar of the currently
playing track. If you do this correctly the beats should overlap
as both tracks play. Dropping a cue track in time with the track
playing out is not easy and does require some practice to get
the hang of.
This diagram shows two tracks (one above and one below) that
start in time but slowly go out of time because they have a
different tempo.
The black marks are the beats.
The short one at the start is the kick drum and the long one
is the snare. The bottom track is faster and you can see how
the beats start to arrive earlier. So if the bottom track is
coming out of your headphones you will start to hear the kick
drum or snare slightly before they hit in the track playing
out. These rhythmical sounds will become muddied and the mix
will sound messy or cluttered. Remember, tracks that have different
tempos once started will drift out of time with the beats getting
less crisp. This means that when you are starting out take your
time ... listen carefully ... did you hear the kick or snare
in your headphone first ... or was it slightly behind? Imagine
the diagram above and get a mental picture of how the beats
relate to one another
